Jeffrey Preston Bezos is an American technology entrepreneur, investor, and philanthropist. He is the founder, chairman, CEO, and president of Amazon.

Bezos was born in Albuquerque, New Mexico, and raised in Houston, Texas. He graduated from Princeton University in 1986 with degrees in electrical engineering and computer science. He worked on Wall Street in a variety of related fields from 1986 to early 1994. He founded Amazon in late 1994 on a cross-country road trip from New York City to Seattle. The company began as an online bookstore and has expanded to a variety of products and services, including video and audio streaming. It is currently the world's largest online sales company, as well as the world's largest provider of cloud infrastructure services via its Amazon Web Services arm.

Bezos added to his business interests when he founded aerospace company Blue Origin in 2000. A Blue Origin test flight successfully first reached space in 2015, and Blue has plans to begin commercial suborbital human spaceflight in 2019. He purchased The Washington Post in 2013 for US$250 million in cash. Bezos manages other business investments through his venture capital fund, Bezos Expeditions.

On July 27, 2017, he became the world's wealthiest person when his estimated net worth increased to just over $90 billion. Bezos's wealth surpassed $100 billion for the first time on November 24, 2017, and he was formally designated the wealthiest person in the world by Forbes on March 6, 2018, with a net worth of $112 billion. The first centi-billionaire on the Forbes wealth index, he was named the "richest man in modern history" after his net worth increased to $150 billion in July 2018.

Early life

Bezos was born Jeffrey Preston Jorgensen on January 12, 1964, in Albuquerque, New Mexico, the son of Jacklyn Gise Jorgensen and Chicago, Illinois, native Ted Jorgensen. At the time of his birth, his mother was a 17-year-old high school student, and his father was a bike shop owner. After Jacklyn divorced Ted, she married Cuban immigrant Miguel "Mike" Bezos in April 1968. Shortly after the wedding, Mike adopted four-year-old Jorgensen, whose surname was then changed to Bezos. The family moved to Houston, Texas, where Mike worked as an engineer for Exxon after he received a degree from the University of New Mexico. Bezos attended River Oaks Elementary School in Houston from fourth to sixth grade.

Bezos is the maternal grandson of Lawrence Preston Gise, a regional director of the U.S. Atomic Energy Commission (AEC) in Albuquerque. Gise retired early to his family's ranch near Cotulla, Texas, where Bezos would spend many summers in his youth. Bezos would later purchase this ranch and grow it from 25,000 acres (10,117 ha) to 300,000 acres (121,406 ha). His maternal grandmother was Mattie Louise Gise (née Strait), through whom he is a cousin of country singer George Strait. Bezos often displayed scientific interests and technological proficiency; he once rigged an electric alarm to keep his younger siblings out of his room.

The family moved to Miami, Florida, where Bezos attended Miami Palmetto High School. While Bezos was in high school, he worked at McDonald's as a short-order line cook during the breakfast shift. He attended the Student Science Training Program at the University of Florida. He was high school valedictorian, a National Merit Scholar, and a Silver Knight Award winner in 1982. In 1986, he graduated from Princeton University with a 4.2 grade point average and Bachelor of Science degrees in electrical engineering and computer science and was a member of Phi Beta Kappa. While at Princeton, he was also elected to Tau Beta Pi and was the president of the Princeton chapter of the Students for the Exploration and Development of Space.

Business career

Early career

After Bezos graduated from Princeton in 1986, he was offered jobs at Intel, Bell Labs, and Andersen Consulting, among others. He first worked at Fitel, a fintech telecommunications start-up, where he was tasked with building a network for international trade. Bezos was promoted to head of development and director of customer service thereafter. He transitioned into the banking industry when he became a product manager at Bankers Trust; he worked there from 1988 to 1990. He then joined D. E. Shaw & Co, a newly founded hedge fund, in 1990 and worked there until 1994. Bezos became D. E. Shaw's fourth senior vice-president at the age of 30.

In late 1993, Bezos decided to start an online bookstore. He left his job at D. E. Shaw and founded Amazon in his garage on July 5, 1994, after writing its business plan on a trip from New York to Seattle. Bezos initially named his new company Cadabra but later changed the name to Amazon after the Amazon River in South America, in part because the name begins with the letter A, which is at the beginning of the alphabet. He accepted an estimated $300,000 from his parents and invested in Amazon. He warned many early investors that there was a 70% chance that Amazon would fail or go bankrupt. Although Amazon was originally an online bookstore, Bezos had always planned to expand to other products. Three years after Bezos founded Amazon, he took it public with an initial public offering (IPO). In response to critical reports from Fortune and Barron's, Bezos maintained that the growth of the Internet would overtake competition from larger book retailers such as Borders and Barnes & Noble.

In 1998, Bezos diversified into the online sale of music and video; by the end of the year, he had also expanded the company's products to include a variety of consumer goods. Bezos used the $54 million raised during the company's 1997 equity offering to finance aggressive acquisition of smaller competitors. In 2002, Bezos led Amazon to launch Amazon Web Services, which compiled data from weather channels and website traffic. In late 2002, rapid spending from Amazon caused it financial distress when revenues stagnated. In 2000, Bezos borrowed $2 billion from banks, as its cash balances dipped to only $350 million. After the company nearly went bankrupt, he closed distribution centers and laid off 14% of the Amazon workforce. In 2003, Amazon rebounded from financial instability and turned a profit of $400 million. In November 2007, Bezos launched the Amazon Kindle. According to a 2008 Time profile, Bezos wished to create the same flow state found in video game simulations in books; he wished readers would fully engage with books. In 2013, Bezos secured a $600 million contract with the Central Intelligence Agency (CIA) on behalf of Amazon Web Services. In October that year, Amazon was recognized as the largest online shopping retailer in the world.

In May 2016, Bezos sold slightly more than one million shares of his holdings in the company for $671 million, the largest sum he had ever raised from selling some of his Amazon stock. On August 4, 2016, Bezos sold another million of his shares for $756.7 million. A year later, Bezos took on 130,000 new employees when he ramped up hiring at company distribution centers. By January 19, 2018, his Amazon stock holdings had appreciated to slightly over $109 billion; months later he began to sell stock to raise cash for other enterprises, in particular, Blue Origin. On January 29, 2018, he was featured in Amazon's Super Bowl commercial. On February 1, 2018, Amazon reported its highest ever profit with quarterly earnings of $2 billion. Due to the growth of Alibaba in China, Bezos has often expressed interest in expanding Amazon into India.

In March 2018, Bezos dispatched Amit Agarwal, Amazon's global senior vice president, to India with $5.5 billion to localize operations throughout the company's supply chain routes. Later in the month, U.S. President Donald Trump accused Amazon–and Bezos, specifically–of sales tax avoidance, misusing postal routes, and anti-competitive business practices. Amazon's share price fell by 9% in response to the President's negative comments; this reduced Bezos's personal wealth by $10.7 billion. Weeks later, Bezos recouped his losses when academic reports out of Stanford University indicated that Trump could do little to regulate Amazon in any meaningful way. During July 2018, a number of members of the U.S. Congress called on Bezos to detail the applications of Amazon's face recognition software, Rekognition. Additionally, statements by the Trump administration, in favor of overturning the antitrust law known as the Paramount Decree, have been predicted to help Amazon acquire the Landmark Theaters chain.

Criticism of Amazon's business practices continued in September 2018 when Senator Bernie Sanders introduced the Stop Bad Employers by Zeroing Out Subsidies (Stop BEZOS) Act and accused Amazon of receiving corporate welfare. This followed revelations by the non-profit group New Food Economy which found that one third of Amazon workers in Arizona, and one tenth of Amazon workers in Pennsylvania and Ohio, relied on food stamps. While preparing to introduce the bill, Sanders opined: "Instead of attempting to explore Mars or go to the moon, how about Jeff Bezos pays his workers a living wage?" He later said: "Bezos could play a profound role. If he said today, nobody who is employed at Amazon will receive less than a living wage, it would send a message to every corporation in America." Sanders's efforts elicited a response from Amazon which pointed to the 130,000 jobs it created in 2017 and called the $28,446 figure for its median salary "misleading" as it included part-time workers. However, Sanders countered that the companies targeted by his proposal have placed an increased focus on part-time workers to escape benefit obligations. On October 2, 2018, Bezos announced a company-wide wage increase, which Sanders applauded. The American workers who were being paid the minimum wage had this increased to $15 per hour — a decision that was interpreted as support for the Fight for $15 movement.

Blue Origin

In September 2000, Bezos founded Blue Origin, a human spaceflight startup company. Bezos has long expressed an interest in space travel and the development of human life in the solar system. He was the valedictorian when he graduated from high school in 1982. His speech was followed up with a Miami Herald interview in which he expressed an interest to build and develop hotels, amusement parks, and colonies for human beings who were in orbit. The 18-year-old Bezos stated that he wanted to preserve Earth from overuse through resource depletion.

After its founding, Blue Origin maintained a low profile until 2006, when it purchased a large tract of land in West Texas for a launch and test facility. After the company gained the public's attention during the late 2000s, Bezos additionally indicated his interest in reducing the cost of space travel for humans while also increasing the safety of extraterrestrial travel. In September 2011, one of the company's unmanned prototype vehicles crashed during a short-hop test flight. Although the crash was viewed as a setback, news outlets noted how far the company went from its founding-to-date in advancing spaceflight. In May 2013, Bezos met with Richard Branson, chairman of Virgin Galactic, to discuss commercial spaceflight opportunities and strategies. He has been compared to Branson and Elon Musk as all three are billionaires who prioritize spaceflight among their business interests.

In 2015, Bezos announced that a new orbital launch vehicle was under development and would make its first flight in the late-2010s. Later in November, Blue Origin's New Shepard space vehicle successfully rocketed into space and reached its planned test altitude of 329,839 feet (100.5 kilometers) before executing a vertical landing back at the launch site in West Texas. In 2016, Bezos allowed select journalists to visit, tour, and photograph his facility. He has repeatedly called for increased inter-space energy and industrial manufacturing to decrease the negative costs associated with business-related pollution.

In December 2017, New Shepard successfully flew and landed dummy passengers, amending and pushing its human space travel start date into late 2018. To execute this program, Blue Origin built six of the vehicles to support all phases of testing and operations: no-passenger test flights, flights with test passengers, and commercial-passenger weekly operations. Since 2016, Bezos has spoken more freely about his hopes to colonize the solar system, and has been selling $1 billion in Amazon stock each year to capitalize Blue Origin in an effort to support this endeavor. In May 2018, Bezos maintained that the primary goal of Blue Origin is to preserve the natural resources of Earth by making the human species multi-planetary. He announced that New Shepard would begin transporting humans into sub-orbital space by November 2018. In July 2018, it was announced that Bezos had priced commercial spaceflight tickets from $200,000 to $300,000 per person.

The Washington Post

On August 5, 2013, Bezos announced his purchase of The Washington Post for $250 million in cash. To execute the sale, he established Nash Holdings, a limited liability holding company that legally owns the paper. The sale closed on October 1, 2013, and Nash Holdings took control. In March 2014, Bezos made his first significant change at The Washington Post and lifted the online paywall for subscribers of a number of U.S. local newspapers in Texas, Hawaii, and Minnesota. In January 2016, Bezos set out to reinvent the newspaper as a media and technology company by reconstructing its digital media, mobile platforms, and analytics software. Throughout the early years of ownership, Bezos was accused of having a potential conflict of interest with the paper. Bezos and the newspaper's editorial board have dismissed accusations that he unfairly controlled the paper's content and Bezos maintains the paper's independence. After a surge in online readership in 2016, the paper was profitable for the first time since Bezos made the purchase in 2013.

Bezos Expeditions

Bezos makes personal investments through his venture capital vehicle, Bezos Expeditions. He was one of the first shareholders in Google, when he invested $250,000 in 1998. That $250,000 investment resulted in 3.3 million shares of Google stock, worth about $3.1 billion in 2017. He also invested in Unity Biotechnology, a life-extension research firm hoping to slow or stop the process of aging. Bezos is involved in the healthcare sector, which includes investments in Unity Biotechnology, Grail, Juno Therapeutics, and ZocDoc. In January 2018, an announcement was made concerning Bezos's role within a new, unnamed healthcare company. This venture, later named Haven, is expected to be a partnership between Amazon, JPMorgan, and Berkshire Hathaway.

Public image

Journalist Nellie Bowles of The New York Times has described the public persona and personality of Bezos as that of "a brilliant but mysterious and coldblooded corporate titan". During the 1990s, Bezos earned a reputation for relentlessly pushing Amazon forward, often at the expense of public charity and social welfare. His business practices projected a public image of prudence and parsimony with his own wealth and that of Amazon. Bezos was a multi-billionaire who hung his clothes on a rack in his Amazon headquarters office and drove a 1996 Honda Accord. Throughout the early 2000s, he was perceived to be geeky or nerdy, often wearing ill-fitting clothing and making a variety of social missteps.

Bezos was seen by the public as needlessly quantitative and data-driven. This perception was detailed by Alan Deutschman who described him as "talking in lists" and "[enumerating] the criteria, in order of importance, for every decision he has made." Select accounts of his persona have drawn controversy and public attention. Notably, journalist Brad Stone wrote an unauthorized book that described Bezos as a demanding boss as well as hyper-competitive. Bezos has been stereotyped as a notoriously opportunistic CEO who operates with little concern for obstacles and externalities. This depiction has been challenged by Bezos himself, his wife, Amazon employees, and the public as a mischaracterization.

During the early 2010s, Bezos solidified his reputation for aggressive business practices, and his public image began to shift. Bezos started to wear tailored clothing; he weight trained, pursued a regimented diet and began to freely spend his money. His physical transformation has been compared to the transformation of Amazon; he is often referred to as the metonym of the company. His physical appearance increased the public's perception of him as a symbolically dominant figure in business and in popular culture, wherein he has been parodied as an enterprising super villain. Since 2017, he has been portrayed by Kyle Mooney and Steve Carrell on Saturday Night Live, usually as an undercutting, domineering figure. Bezos eats exotic foods, such as octopus and roasted iguana. In May 2014, the International Trade Union Confederation named Bezos the "World's Worst Boss", with its general secretary Sharan Burrow saying: "Jeff Bezos represents the inhumanity of employers who are promoting the North American corporate model." During the late 2010s, Bezos reversed his reputation for being reluctant to spend money on non-business-related expenses. His relative lack of philanthropy compared to other billionaires has drawn a negative response from the public since 2016. Bezos has been known to publicly contest claims made in critical articles, as exemplified in 2015 when he sent a memo to employees denouncing a New York Times piece.

Leadership style

"Day 1" Management Philosophy
Day 1: start up
Day 2: stasis
Day 3: irrelevance
Day 4: "excruciating, painful decline"
Day 5: death
Bezos has stated "it is always Day 1" to describe his growth mindset.

Bezos used what he called a "regret-minimization framework" while he worked at D. E. Shaw and again during the early years of Amazon. He described this life philosophy by stating: "When I'm 80, am I going to regret leaving Wall Street? No. Will I regret missing the beginning of the Internet? Yes." During the 1990s and early 2000s at Amazon, he was characterized as trying to quantify all aspects of running the company, often listing employees on spreadsheets and basing executive decisions on data. To push Amazon forward, Bezos developed the mantra "Get Big Fast", which spoke to the company's need to scale its operations and establish market dominance. He favored diverting Amazon profits back into the company in lieu of allocating it amongst shareholders in the form of dividends.

Bezos uses the term "work–life harmony" instead of the more standard work–life balance because he believes balance implies that you can have one and not the other. He believes that work and home life are interconnected, informing and calibrating each other. Journalist Walt Mossberg dubbed the idea that someone who cannot tolerate criticism or critique shouldn't do anything new or interesting, "The Bezos Principle". Bezos does not schedule early morning meetings and enforces a two-pizza rule–a preference for meetings to be small enough to where two pizzas can feed everyone in the board room. When interviewing candidates for jobs at Amazon he has stated he considers three inquiries: can he admire the person, can the person raise the common standard, and under what circumstances could the person become exemplary.

He meets with Amazon investors for a total of only six hours a year. Instead of using PowerPoints, Bezos requires high-level employees to present information with six-page narratives. Starting in 1998, Bezos publishes an annual letter for Amazon shareholders wherein he frequently refers to five principles: focus on customers not competitors, take risks for market leadership, facilitate staff morale, build a company culture, and empower people. Bezos maintains the email address "jeff@amazon.com" as an outlet for customers to reach out to him and the company. Although he does not respond to the emails, he forwards some of them with a question mark in the subject line to executives who attempt to address the issues. Bezos has cited Warren Buffett (of Berkshire Hathaway), Jamie Dimon (of JPMorgan Chase), and Bob Iger (of Walt Disney) as major influences on his leadership style.

Recognition

In 1999, Bezos received his first major award when Time named him Person of the Year. In 2008, he was selected by U.S. News & World Report as one of America's best leaders. Bezos was awarded an honorary doctorate in science and technology from Carnegie Mellon University in 2008. In 2011, The Economist gave Bezos and Gregg Zehr an Innovation Award for the Amazon Kindle. In 2012, Bezos was named Businessperson of the Year by Fortune. He is also a member of the Bilderberg Group and attended the 2011 Bilderberg conference in St. Moritz, Switzerland, and the 2013 conference in Watford, Hertfordshire, England. He was a member of the Executive Committee of The Business Council for 2011 and 2012. In 2014, he was ranked the best-performing CEO in the world by Harvard Business Review.

He has also figured in Fortune's list of 50 great leaders of the world for three straight years, topping the list in 2015. In September 2016, Bezos received a $250,000 prize for winning the Heinlein Prize for Advances in Space Commercialization, which he donated to the Students for the Exploration and Development of Space. In February 2018, Bezos was elected to the National Academy of Engineering for "leadership and innovation in space exploration, autonomous systems, and building a commercial pathway for human space flight". In March 2018, at the Explorers Club annual dinner, he was awarded the Buzz Aldrin Space Exploration Award in recognition of his work with Blue Origin. He received Germany's 2018 Axel Springer Award for Business Innovation and Social Responsibility. Time magazine named him one of the 100 most influential people in the world in their 2018 listing.

Additional reference(s): Bloomberg Billionaires Index

Bezos first became a millionaire in 1997 after raising $54 million through Amazon's initial public offering (IPO). He was first included on Forbes The World's Billionaires list in 1999 with a registered net worth of $10.1 billion. His net worth decreased to $6.1 billion a year later, a 40.5% drop. His wealth plummeted even more the following year, dropping 66.6% to $2.0 billion. He lost $500 million the following year, which brought his net worth down to $1.5 billion. The following year, his net worth increased by 104% to $2.5 billion. From 2005 to 2007, he quadrupled his net worth to $8.7 billion. After the financial crisis and succeeding economic recession, his net worth would erode to $6.8 billion—a 17.7% drop. His wealth rose by 85.2% in 2010, leaving him with $12.6 billion. This percentage increase ascended him to the 43rd spot on the ranking from 68th.

After a rumor broke out that Amazon was developing a smartphone, Bezos's net worth rose to $30.5 billion in 2014. A year later, Bezos entered the top ten when he increased his net worth to a total of $50.3 billion. Bezos rose to be the 5th richest person in the world hours before market close; he gained $7 billion in one hour. By the time the Forbes list was calculated in March 2016, his net worth was registered at $45.2 billion. However, just months later in October 2016, his wealth increased by $16.2 billion to $66.5 billion unofficially ranking him the third richest person in the world behind Warren Buffett. After sporadic jumps in Amazon's share price, in July 2017 he briefly unseated Microsoft cofounder Bill Gates as the wealthiest person in the world.

The net worth of Jeff Bezos from 1999 to 2018 as estimated by Forbes magazine, in the nominal U.S. dollar. His net worth is calculated in the billions by March of each year.
 
Bezos would continue to sporadically surpass Gates throughout the month of October 2017 after Amazon's share price fluctuated. His net worth surpassed $100 billion for the first time on November 24, 2017, after Amazon's share price increased by more than 2.5%. When the 2017 list was issued, Bezos's net worth was registered at $72.8 billion, adding $27.6 billion from the previous year. Bezos was officially ranked as the third wealthiest person in the world up from the 5th spot in 2016. His wealth's rapid growth from 2016 to 2017 sparked a variety of assessments about how much money Bezos earned on a controlled, reduced time scale. On October 10, 2017, he made an estimated $6.24 billion in 5 minutes, slightly less than the annual Gross Domestic Product of Kyrgyzstan.

On March 6, 2018, Bezos was officially designated the wealthiest person in the world with a registered net worth of $112 billion. He unseated Bill Gates ($90 billion) who was $6 billion ahead of Warren Buffett ($84 billion), ranked third. He is considered the first registered centi-billionaire (not adjusted for inflation).

His wealth, in 2017–18 terms, equaled that of 2.7 million Americans. Bezos's net worth increased by $33.6 billion from January 2017 to January 2018. This increase outstripped the economic development (in GDP terms) of more than 96 countries around the world. During March 9, Bezos earned $230,000 every 60 seconds. The Motley Fool estimated that if Bezos had not sold any of his shares from its original public offering in 1997, his net worth would sit at $181 billion in 2018. According to Quartz, his net worth of $150 billion in July 2018 was enough to purchase the entire stock markets of Nigeria, Hungary, Egypt, Luxembourg, and Iran. Following the report by Quartz, Amazon workers in Poland, Germany, and Spain participated in demonstrations and labor strikes to draw attention to his growing wealth and the lack of compensation, labor rights, and satisfactory working conditions of select Amazon workers. On July 17, 2018 he was designated the "wealthiest person in modern history" by the Bloomberg Billionaires Index, Fortune, MarketWatch, The Wall Street Journal, and Forbes.

Bezos's wealth may be considerably reduced by his divorce with wife MacKenzie Bezos. According to Forbes, if the Washington state common law applies for their divorce without a prenuptial agreement Bezos's wealth will be split 50–50 with his ex-wife. In this case, she would become the wealthiest woman in the world.

Personal life

In 1992, Bezos was working for D. E. Shaw in Manhattan, New York City, when he met novelist MacKenzie Tuttle, who was a research associate at the firm; the couple married a year later. In 1994, they moved across the country to Seattle, Washington, where Bezos founded Amazon. He and his wife are the parents of four children: three sons, and one daughter adopted from China.

In March 2003, Bezos was one of three passengers in a helicopter that crashed in West Texas after the craft's tail boom hit a tree. Bezos sustained minor injuries and was discharged from a local hospital the same day.

In 2016, Bezos played a Starfleet official in the movie Star Trek Beyond, and joined the cast and crew at a San Diego Comic-Con screening.

On January 9, 2019, Bezos and his wife of 25 years, MacKenzie, announced on Twitter their intent to divorce after a "long period" of separation. On April 4, 2019, the divorce was finalized, with Bezos keeping 75% of the couple's Amazon stock and MacKenzie getting the remaining 25% ($35.6 billion) in Amazon stock. However, Bezos would keep all of the couple's voting rights.

On February 7, 2019, Bezos published an online essay in which he accused American Media, Inc. owner David Pecker of "extortion and blackmail" for threatening to publish intimate photos of Bezos and Lauren Sánchez, if he did not stop his investigation into how his text messages and other photos had been leaked to the National Enquirer.

Politics

According to public campaign finance records, Bezos supported the electoral campaigns of Patty Murray and Maria Cantwell, two Democratic U.S. Senators from Washington. He has also supported U.S. representative John Conyers, as well as Patrick Leahy and Spencer Abraham, U.S. Senators serving on committees dealing with Internet-related issues. Bezos and his wife support the legalization of same-sex marriage, and in 2012 contributed $2.5 million to Washington United for Marriage, a group supporting a yes vote on Washington Referendum 74, which affirmed a same-sex marriage law enacted in the state. Bezos donated $100,000 towards a movement against a higher Washington state income tax in 2010. In 2012, he donated to Amazon's political action committee (PAC), which has given $56,000 and $74,500 to Democrats and Republicans, respectively.

After the 2016 presidential election, Bezos was invited to join Donald Trump's Defense Innovation Advisory Board, an advisory council to improve the technology used by the Defense Department. Bezos declined the offer without further comment. Trump has repeatedly attacked Bezos via Twitter, accused Bezos of avoiding corporate taxes, gaining undue political influence, and undermining his presidency by spreading "fake news." Bezos has repeatedly joked about using his rocket company to send Donald Trump into outer space.

In 2014, Amazon won a bid for a cloud computing contract with the CIA valued at $600 million. A 2018, $10 billion contract known as the Joint Enterprise Defense Infrastructure (JEDI) project, this time with the Pentagon, was allegedly written up in a way that favors Amazon. Controversy over this was raised when General James Mattis accepted a headquarters tour invitation from Bezos and co-ordinated the deal through Sally Donnelly, a lobbyist who previously worked for Amazon. Despite Bezos's support for an open borders policy towards immigrants, Amazon has actively marketed facial recognition software to the ICE.

In March 2018, Bezos met in Seattle with Mohammad bin Salman, the crown prince and de facto ruler of Saudi Arabia, to discuss investment opportunities for Saudi Vision 2030.

Philanthropy

Bezos funded the retrieval of this F-1 engine from the bottom of the Atlantic Ocean in 2015, eventually donating it to the Seattle Museum of Flight.
 
Bezos supports philanthropic efforts through direct donations and non-profit projects funded by Bezos Expeditions. Bezos used Bezos Expeditions to fund several philanthropic projects, including an Innovation center at the Seattle Museum of History and Industry and the Bezos Center for Neural Circuit Dynamics at Princeton Neuroscience Institute. Bezos donated to the Fred Hutchinson Cancer Research Center several times between 2009 and 2017. In 2013, he pledged $500,000 to Worldreader, a non-profit founded by a former Amazon employee. Also in 2013, Bezos funded the recovery of two Saturn V first-stage Rocketdyne F-1 engines from the floor of the Atlantic Ocean. They were positively identified as belonging to the Apollo 11 mission's S-1C stage from July 1969.[219][220] The engine is currently on display at the Seattle Museum of Flight. His philanthropic efforts have been negatively compared to those of Bill Gates and Warren Buffett.

On May 23, 2017, Bezos gave $1 million to the Reporters Committee for Freedom of the Press, which provides pro bono legal services for American journalists. On June 15, 2017, he posted a message on Twitter asking for ideas for philanthropy: "I'm thinking about a philanthropy strategy that is the opposite of how I mostly spend my time—working on the long term". At the time of the post, Bezos's lifetime spending on charitable causes was estimated to be $100 million. Multiple journalists responded by asking Bezos to pay higher wages to Amazon warehouse workers. A year later in June, he tweeted that he would announce two philanthropic foci by the end of summer 2018. Bezos announced in September 2018 that he would commit approximately $2 billion to a fund to deal with American homelessness and establish a network of non-profit preschools for low income communities. As part of this announcement, he committed to establishing the "Day 1 Families Fund" to finance "night shelters and day care centers for homeless families" and the "Day 1 Academies Fund" for early childhood education.

In January 2018, Bezos made a $33 million donation to TheDream.US, a college scholarship fund for undocumented immigrants brought to the United States as minors. In June 2018, Bezos donated to Breakthrough Energy Ventures, a private philanthropic fund founded by Bill Gates aimed at promoting emissions-free energy. In September 2018, Bezos donated $10 million to With Honor, a nonpartisan organization that works to increase the number of veterans in political office.

Orbital hybridisation

From Wikipedia, the free encyclopedia

In chemistry, orbital hybridisation (or hybridization) is the concept of mixing atomic orbitals into new hybrid orbitals (with different energies, shapes, etc., than the component atomic orbitals) suitable for the pairing of electrons to form chemical bonds in valence bond theory. Hybrid orbitals are very useful in the explanation of molecular geometry and atomic bonding properties and are symmetrically disposed in space. Although sometimes taught together with the valence shell electron-pair repulsion (VSEPR) theory, valence bond and hybridisation are in fact not related to the VSEPR model.

History and uses

Chemist Linus Pauling first developed the hybridisation theory in 1931 to explain the structure of simple molecules such as methane (CH4) using atomic orbitals. Pauling pointed out that a carbon atom forms four bonds by using one s and three p orbitals, so that "it might be inferred" that a carbon atom would form three bonds at right angles (using p orbitals) and a fourth weaker bond using the s orbital in some arbitrary direction. In reality, methane has four bonds of equivalent strength separated by the tetrahedral bond angle of 109.5°. Pauling explained this by supposing that in the presence of four hydrogen atoms, the s and p orbitals form four equivalent combinations or hybrid orbitals, each denoted by sp3 to indicate its composition, which are directed along the four C-H bonds. This concept was developed for such simple chemical systems, but the approach was later applied more widely, and today it is considered an effective heuristic for rationalising the structures of organic compounds. It gives a simple orbital picture equivalent to Lewis structures

Hybridisation theory is an integral part of organic chemistry, one of the most compelling examples being Baldwin's rules. For drawing reaction mechanisms sometimes a classical bonding picture is needed with two atoms sharing two electrons. Hybridisation theory explains bonding in alkenes and methane. The amount of p character or s character, which is decided mainly by orbital hybridisation, can be used to reliably predict molecular properties such as acidity or basicity.

Overview

Orbitals are a model representation of the behaviour of electrons within molecules. In the case of simple hybridisation, this approximation is based on atomic orbitals, similar to those obtained for the hydrogen atom, the only neutral atom for which the Schrödinger equation can be solved exactly. In heavier atoms, such as carbon, nitrogen, and oxygen, the atomic orbitals used are the 2s and 2p orbitals, similar to excited state orbitals for hydrogen.

Hybrid orbitals are assumed to be mixtures of atomic orbitals, superimposed on each other in various proportions. For example, in methane, the C hybrid orbital which forms each carbonhydrogen bond consists of 25% s character and 75% p character and is thus described as sp3 (read as s-p-three) hybridised. Quantum mechanics describes this hybrid as an sp3 wavefunction of the form N(s + 3pσ), where N is a normalisation constant (here 1/2) and pσ is a p orbital directed along the C-H axis to form a sigma bond. The ratio of coefficients (denoted λ in general) is 3 in this example. Since the electron density associated with an orbital is proportional to the square of the wavefunction, the ratio of p-character to s-character is λ2 = 3. The p character or the weight of the p component is N2λ2 = 3/4.

Types of hybridisation

sp3

Four sp3 orbitals.

Hybridisation describes the bonding atoms from an atom's point of view. For a tetrahedrally coordinated carbon (e.g., methane CH4), the carbon should have 4 orbitals with the correct symmetry to bond to the 4 hydrogen atoms.

Carbon's ground state configuration is 1s2 2s2 2p2 or more easily read: 

C ↑↓ ↑↓  
1s 2s 2p 2p 2p

The carbon atom can use its two singly occupied p-type orbitals, to form two covalent bonds with two hydrogen atoms, yielding the singlet methylene CH2, the simplest carbene. The carbon atom can also bond to four hydrogen atoms by an excitation (or promotion) of an electron from the doubly occupied 2s orbital to the empty 2p orbital, producing four singly occupied orbitals. 

C* ↑↓
1s 2s 2p 2p 2p

The energy released by formation of two additional bonds more than compensates for the excitation energy required, energetically favouring the formation of four C-H bonds.

Quantum mechanically, the lowest energy is obtained if the four bonds are equivalent, which requires that they are formed from equivalent orbitals on the carbon. A set of four equivalent orbitals can be obtained that are linear combinations of the valence-shell (core orbitals are almost never involved in bonding) s and p wave functions, which are the four sp3 hybrids. 

C* ↑↓
1s sp3 sp3 sp3 sp3

In CH4, four sp3 hybrid orbitals are overlapped by hydrogen 1s orbitals, yielding four σ (sigma) bonds (that is, four single covalent bonds) of equal length and strength.

sp2

Three sp2 orbitals.
 
Ethene structure
 
Other carbon compounds and other molecules may be explained in a similar way. For example, ethene (C2H4) has a double bond between the carbons. 

For this molecule, carbon sp2 hybridises, because one π (pi) bond is required for the double bond between the carbons and only three σ bonds are formed per carbon atom. In sp2 hybridisation the 2s orbital is mixed with only two of the three available 2p orbitals, 

C* ↑↓
1s sp2 sp2 sp2 2p

forming a total of three sp2 orbitals with one remaining p orbital. In ethylene (ethene) the two carbon atoms form a σ bond by overlapping one sp2 orbital from each carbon atom. The π bond between the carbon atoms perpendicular to the molecular plane is formed by 2p–2p overlap. Each carbon atom forms covalent C–H bonds with two hydrogens by s–sp2 overlap, all with 120° bond angles. The hydrogen–carbon bonds are all of equal strength and length, in agreement with experimental data.

sp

Two sp orbitals
 
The chemical bonding in compounds such as alkynes with triple bonds is explained by sp hybridisation. In this model, the 2s orbital is mixed with only one of the three p orbitals, 

C* ↑↓
1s sp sp 2p 2p

resulting in two sp orbitals and two remaining p orbitals. The chemical bonding in acetylene (ethyne) (C2H2) consists of sp–sp overlap between the two carbon atoms forming a σ bond and two additional π bonds formed by p–p overlap. Each carbon also bonds to hydrogen in a σ s–sp overlap at 180° angles.

Hybridisation and molecule shape

Hybridisation helps to explain molecule shape, since the angles between bonds are (approximately) equal to the angles between hybrid orbitals, as explained above for the tetrahedral geometry of methane. As another example, the three sp2 hybrid orbitals are at angles of 120° to each other, so this hybridisation favours trigonal planar molecular geometry with bond angles of 120°. Other examples are given in the table below. 

Classification Main group Transition metal
AX2
  • Linear (180°)
  • sp hybridisation
  • E.g., CO2
  • Bent (90°)
  • sd hybridisation
  • E.g., VO2+
AX3
AX4
AX6

For two equivalent spx hybrids, the bond angle between them is given by , while for two equivalent sdx hybrids, the bond angle between them is given by . There are no shapes with ideal bond angles corresponding to sd4 hybridisation as there is no regular 10-vertex polyhedron. Nonetheless, molecules such as Ta(CH3)5 with sd4 hybridisation adopt a square pyramidal shape.

Hybridisation of hypervalent molecules

Valence shell expansion

Hybridisation is often presented for main group AX5 and above, as well as for many transition metal complexes, using the hybridisation scheme first proposed by Pauling. 

Classification Main group
AX5
AX6
AX7
Classification Transition metal
AX4 (d8)
AX6 (d6)
  • Octahedral (90°)
  • d2sp3 hybridisation
  • E.g., Mo(CO)6
Note: AX5 and AX7 have variable molecular shapes

In this notation, d orbitals of main group atoms are listed after the s and p orbitals since they have the same principal quantum number (n), while d orbitals of transition metals are listed first since the s and p orbitals have a higher n. Thus for AX6 molecules, sp3d2 hybridisation in the S atom involves 3s, 3p and 3d orbitals, while d2sp3 for Mo involves 4d, 5s and 5p orbitals.

Contrary evidence

In 1990, Magnusson published a seminal work definitively excluding the role of d-orbital hybridisation in bonding in hypervalent compounds of second-row (period 3) elements, ending a point of contention and confusion. Part of the confusion originates from the fact that d-functions are essential in the basis sets used to describe these compounds (or else unreasonably high energies and distorted geometries result). Also, the contribution of the d-function to the molecular wavefunction is large. These facts were incorrectly interpreted to mean that d-orbitals must be involved in bonding.

For transition metal centres, the d and s orbitals are the primary valence orbitals, which are only weakly supplemented by the p orbitals. The question of whether the p orbitals actually participate in bonding has not been definitively resolved, but all studies indicate they play a minor role.

Resonance

In light of computational chemistry, a better treatment would be to invoke sigma bond resonance in addition to hybridisation, which implies that each resonance structure has its own hybridisation scheme. For main group compounds, all resonance structures must obey the octet (8-electron) rule. For transition metal compounds, the resonance structures that obey the duodectet (12-electron) rule suffice to describe bonding, with optional inclusion of dmspn resonance structures.

Isovalent hybridisation

Although ideal hybrid orbitals can be useful, in reality most bonds require orbitals of intermediate character. This requires an extension to include flexible weightings of atomic orbitals of each type (s, p, d) and allows for a quantitative depiction of bond formation when the molecular geometry deviates from ideal bond angles. The amount of p-character is not restricted to integer values; i.e., hybridisations like sp2.5 are also readily described.

The hybridisation of bond orbitals is determined by Bent's rule: "Atomic s character concentrates in orbitals directed towards electropositive substituents".

Molecules with lone pairs

For molecules with lone pairs, the bonding orbitals are isovalent spx hybrids. For example, the two bond-forming hybrid orbitals of oxygen in water can be described as sp4.0 to give the interorbital angle of 104.5°. This means that they have 20% s character and 80% p character and does not imply that a hybrid orbital is formed from one s and four p orbitals on oxygen since the 2p subshell of oxygen only contains three p orbitals. The shapes of molecules with lone pairs are:
  • Trigonal pyramidal (>90°)
    • Three spx bond hybrids
    • E.g., NH3
  • Bent (>90°)
    • Two spx bond hybrids
    • E.g., SO2, H2O
In such cases, there are two mathematically equivalent ways of representing lone pairs. They can be represented by orbitals of sigma and pi symmetry similar to molecular orbital theory or by equivalent orbitals similar to VSEPR theory.

Hypervalent molecules

For hypervalent molecules with lone pairs, the bonding scheme can be split into a hypervalent component and a component consisting of isovalent spx bond hybrids. The hypervalent component consists of resonant bonds using p orbitals. The table below shows how each shape is related to the two components and their respective descriptions.

Hybridisation defects

Hybridisation of s and p orbitals to form effective spx hybrids requires that they have comparable radial extent. While 2p orbitals are on average less than 10% larger than 2s, in part attributable to the lack of a radial node in 2p orbitals, 3p orbitals which have one radial node, exceed the 3s orbitals by 20–33%. The difference in extent of s and p orbitals increases further down a group. The hybridisation of atoms in chemical bonds can be analysed by considering localised molecular orbitals, for example using natural localised molecular orbitals in a natural bond orbital (NBO) scheme. In methane, CH4, the calculated p/s ratio is approximately 3 consistent with "ideal" sp3 hybridisation, whereas for silane, SiH4, the p/s ratio is closer to 2. A similar trend is seen for the other 2p elements. Substitution of fluorine for hydrogen further decreases the p/s ratio. The 2p elements exhibit near ideal hybridisation with orthogonal hybrid orbitals. For heavier p block elements this assumption of orthogonality cannot be justified. These deviations from the ideal hybridisation were termed hybridisation defects by Kutzelnigg.

Photoelectron spectra

One misconception concerning orbital hybridisation is that it incorrectly predicts the ultraviolet photoelectron spectra of many molecules. While this is true if Koopmans' theorem is applied to localised hybrids, quantum mechanics requires that the (in this case ionised) wavefunction obey the symmetry of the molecule which implies resonance in valence bond theory. For example, in methane, the ionised states (CH4+) can be constructed out of four resonance structures attributing the ejected electron to each of the four sp3 orbitals. A linear combination of these four structures, conserving the number of structures, leads to a triply degenerate T2 state and a A1 state. The difference in energy between each ionised state and the ground state would be an ionisation energy, which yields two values in agreement with experiment.

Localized MOs vs canonical MOs

Bonding orbitals formed from hybrid atomic orbitals may be considered as localized molecular orbitals, which can be formed from the delocalised orbitals of molecular orbital theory by an appropriate mathematical transformation. For molecules in the ground state, this transformation of the orbitals leaves the total many-electron wave function unchanged. The hybrid orbital description of the ground state is therefore equivalent to the delocalised orbital description for ground state total energy and electron density, as well as the molecular geometry that corresponds to the minimum total energy value.

Two localized representations

Molecules with multiple bonds or multiple lone pairs can have orbitals represented in terms of sigma and pi symmetry or equivalent orbitals. Different valence bond methods use either of the two representations, which have mathematically equivalent total many-electron wave functions and are related by a unitary transformation of the set of occupied molecular orbitals. 

For multiple bonds, the sigma-pi representation is the predominant one compared to the equivalent orbital (bent bond) representation. In contrast, for multiple lone pairs, most textbooks use the equivalent orbital representation. However, the sigma-pi representation is also used, such as by Weinhold and Landis within the context of natural bond orbitals, a localized orbital theory containing modernized analogs of classical (valence bond/Lewis structure) bonding pairs and lone pairs. For the hydrogen fluoride molecule, for example, two F lone pairs are essentially unhybridized p orbitals, while the other is an spx hydrid orbital. An analogous consideration applies to water (one O lone pair is in a pure p orbital, another is in an spx hybrid orbital).
