William Henry "Bill" Gates III (born October 28, 1955)
[4] is an American 
business magnateand philanthropist. Gates is the former chief executive and current chairman of 
Microsoft, the world’s largest personal-computer 
software company, which he co-founded with 
Paul Allen. He is consistently ranked among the 
world's wealthiest people[5] and was the wealthiest overall from 1995 to 2009, excluding 2008, when he was ranked third;
[6] in 2011 he was the wealthiest American and the second wealthiest person.
[7][8] During his career at Microsoft, Gates held the positions of CEO and 
chief software architect, and remains the largest individual shareholder, with 6.4 percent of the 
common stock.
[9] He has also authored or co-authored several books.
 
Gates stepped down as chief executive officer of Microsoft in January 2000. He remained as chairman and created the position of chief software architect. In June 2006, Gates announced that he would be transitioning from full-time work at Microsoft to part-time work, and full-time work at the Bill & Melinda Gates Foundation. He gradually transferred his duties to 
Ray Ozzie, chief software architect, and 
Craig Mundie, chief research and 
Early life
Gates was born in 
Seattle, Washington, to 
William H. Gates, Sr. and 
Mary Maxwell Gates. His parents are of English, 
German, and Scots-Irish descent.
[13][14] His father was a prominent lawyer, and his mother served on the board of directors for 
First Interstate BancSystem and the 
United Way. Gates's maternal grandfather was J. W. Maxwell, a 
national bank president. Gates has one elder sister, Kristi (Kristianne), and one younger sister, Libby. He was the fourth of his name in his family, but was known as William Gates III or "Trey" because his father had the "II" suffix.
[15] Early on in his life, Gates's parents had a law career in mind for him.
[16] When Gates was young, his family regularly attended a 
Congregational church.
[17][18][19]
At 13 he enrolled in the 
Lakeside School, an exclusive preparatory school.
[20] When he was in the eighth grade, the Mothers Club at the school used proceeds from Lakeside School's 
rummage sale to buy a 
Teletype Model 33 ASR terminal and a block of computer time on a
General Electric (GE) computer for the school's students.
[21] Gates took an interest in programming the GE system in 
BASIC, and was excused from math classes to pursue his interest. He wrote his first computer program on this machine: an implementation of 
tic-tac-toethat allowed users to play games against the computer. Gates was fascinated by the machine and how it would always execute software code perfectly. When he reflected back on that moment, he said, "There was just something neat about the machine."
[22] After the Mothers Club donation was exhausted, he and other students sought time on systems including 
DEC PDP minicomputers. One of these systems was a 
PDP-10 belonging to Computer Center Corporation (CCC), which banned four Lakeside students—Gates, 
Paul Allen, 
Ric Weiland, and Kent Evans—for the summer after it caught them exploiting bugs in the 
operating system to obtain free computer time.
[23]
At the end of the ban, the four students offered to find bugs in CCC's software in exchange for computer time. Rather than use the system via Teletype, Gates went to CCC's offices and studied 
source code for various programs that ran on the system, including programs in
FORTRAN, 
LISP, and 
machine language. The arrangement with CCC continued until 1970, when the company went out of business. The following year, Information Sciences, Inc. hired the four Lakeside students to write a payroll program in 
COBOL, providing them computer time and royalties. After his administrators became aware of his programming abilities, Gates wrote the school's computer program to schedule students in classes. He modified the code so that he was placed in classes with mostly female students. He later stated that "it was hard to tear myself away from a machine at which I could so unambiguously demonstrate success."
[22] At age 17, Gates formed a venture with Allen, called 
Traf-O-Data, to make 
traffic counters based on the 
Intel 8008 processor.
[24] In early 1973, Bill Gates served as a congressional page in the U.S. House of Representatives.
[25]
Gates graduated from Lakeside School in 1973. He scored 1590 out of 1600 on the 
SAT[26] and enrolled at 
Harvard College in the autumn of 1973.
[27] While at Harvard, he met 
Steve Ballmer, who later succeeded Gates as CEO of Microsoft.
In his sophomore year, Gates devised an algorithm for 
pancake sorting as a solution to one of a series of unsolved problems
[28] presented in a 
combinatorics class by 
Harry Lewis, one of his professors. Gates's solution held the record as the fastest version for over thirty years;
[28][29] its successor is faster by only one percent.
[28] His solution was later formalized in a published paper in collaboration with Harvard computer scientist 
Christos Papadimitriou.
[30]
Gates did not have a definite study plan while a student at Harvard
[31] and spent a lot of time using the school's computers. Gates remained in contact with Paul Allen, and he joined him at Honeywell during the summer of 1974.
[32] The following year saw the release of the 
MITS Altair 8800 based on the 
Intel 8080 CPU, and Gates and Allen saw this as the opportunity to start their own computer software company.
[33] Gates dropped out of Harvard at this time.
[34] He had talked this decision over with his parents, who were supportive of him after seeing how much Gates wanted to start a company.
[31]

After reading the January 1975 issue of 
Popular Electronics that demonstrated the 
Altair 8800, Gates contacted 
Micro Instrumentation and Telemetry Systems (MITS), the creators of the new microcomputer, to inform them that he and others were working on a 
BASIC interpreter for the platform.
[35] In reality, Gates and Allen did not have an Altair and had not written code for it; they merely wanted to gauge MITS's interest. MITS president 
Ed Roberts agreed to meet them for a demo, and over the course of a few weeks they developed an Altair 
emulator that ran on a minicomputer, and then the BASIC interpreter. The demonstration, held at MITS's offices in
Albuquerque was a success and resulted in a deal with MITS to distribute the interpreter as
Altair BASIC. Paul Allen was hired into MITS,
[36] and Gates took a leave of absence from Harvard to work with Allen at MITS in Albuquerque in November 1975. They named their partnership "Micro-Soft" and had their first office located in Albuquerque.
[36] Within a year, the hyphen was dropped, and on November 26, 1976, the trade name "Microsoft" was registered with the Office of the Secretary of the 
State of New Mexico.
[36] Gates never returned to Harvard to complete his studies.
Microsoft's BASIC was popular with computer hobbyists, but Gates discovered that a pre-market copy had leaked into the community and was being widely copied and distributed. In February 1976, Gates wrote an 
Open Letter to Hobbyists in the MITS newsletter saying that MITS could not continue to produce, distribute, and maintain high-quality software without payment.
[37] This letter was unpopular with many computer hobbyists, but Gates persisted in his belief that software developers should be able to demand payment. Microsoft became independent of MITS in late 1976, and it continued to develop programming language software for various systems.
[36] The company moved from Albuquerque to its new home in 
Bellevue, Washington on January 1, 1979, after the former rejected his loan application.
[35]
During Microsoft's early years, all employees had broad responsibility for the company's business. Gates oversaw the business details, but continued to write code as well. In the first five years, Gates personally reviewed every line of code the company shipped, and often rewrote parts of it as he saw fit.
[38]
IBM partnership
IBM approached Microsoft in July 1980 regarding its upcoming personal computer, the 
IBM PC.
[39] The computer company first proposed that Microsoft write the BASIC interpreter. When IBM's representatives mentioned that they needed an operating system, Gates referred them to 
Digital Research (DRI), makers of the widely used 
CP/M operating system.
[40] IBM's discussions with Digital Research went poorly, and they did not reach a licensing agreement. IBM representative Jack Sams mentioned the licensing difficulties during a subsequent meeting with Gates and told him to get an acceptable operating system. A few weeks later Gates proposed using 
86-DOS(QDOS), an operating system similar to CP/M that 
Tim Paterson of 
Seattle Computer Products (SCP) had made for hardware similar to the PC. Microsoft made a deal with SCP to become the exclusive licensing agent, and later the full owner, of 86-DOS. After adapting the operating system for the PC, Microsoft delivered it to IBM as 
PC-DOS in exchange for a one-time fee of $50,000.
[41] 
Gates did not offer to transfer the 
copyright on the operating system, because he believed that other hardware vendors would clone IBM's system.
[41] They did, and the sales of 
MS-DOS made Microsoft a major player in the industry.
[42] Despite IBM's name on the operating system the press quickly identified Microsoft as being very influential on the new computer, with 
PC Magazine asking if Gates were "The Man Behind The Machine?"
[39] He oversaw Microsoft's company restructuring on June 25, 1981, which re-incorporated the company in Washington state and made Gates President of Microsoft and the Chairman of the Board.
[35]
Windows
Microsoft launched its first retail version of 
Microsoft Windows on November 20, 1985, and in August, the company struck a deal with 
IBMto develop a separate operating system called 
OS/2. Although the two companies successfully developed the first version of the new system, mounting creative differences caused the partnership to deteriorate. It ended in 1991, when Gates led Microsoft to develop a version of OS/2 independently from IBM.
[43]
Management style
From Microsoft's founding in 1975 until 2006, Gates had primary responsibility for the company's product strategy. He aggressively broadened the company's range of products, and wherever Microsoft achieved a dominant position he vigorously defended it. He gained a reputation for being distant to others; as early as 1981 an industry executive complained in public that "Gates is notorious for not being reachable by phone and for not returning phone calls."
[44]
As an executive, Gates met regularly with Microsoft's senior managers and program managers. Firsthand accounts of these meetings describe him as verbally combative, berating managers for perceived holes in their business strategies or proposals that placed the company's long-term interests at risk.
[45][46] He often interrupted presentations with such comments as, "That's the stupidest thing I've ever heard!"
[47] and, "Why don't you just give up your 
options and join the 
Peace Corps?"
[48] The target of his outburst then had to defend the proposal in detail until, hopefully, Gates was fully convinced.
[47] When subordinates appeared to be procrastinating, he was known to remark sarcastically, "I'll do it over the weekend."
[49][50][51]
Gates's role at Microsoft for most of its history was primarily a management and executive role. However, he was an active software developer in the early years, particularly on the company's 
programming language products. He has not officially been on a development team since working on the 
TRS-80 Model 100,
[52] but wrote code as late as 1989 that shipped in the company's products.
[50] On June 15, 2006, Gates announced that he would transition out of his day-to-day role over the next two years to dedicate more time to philanthropy. He divided his responsibilities between two successors, placing 
Ray Ozzie in charge of day-to-day management and 
Craig Mundie in charge of long-term product strategy.
[53]
Antitrust litigation

Many decisions that led to 
antitrust litigation over Microsoft's business practices have had Gates's approval. In the 1998 
United States v. Microsoft case, Gates gave deposition testimony that several journalists characterized as evasive. He argued with examiner 
David Boies over the contextual meaning of words such as, "compete", "concerned", and "we".
[54] BusinessWeekreported:
Early rounds of his deposition show him offering obfuscatory answers and saying 'I don't recall,' so many times that even the presiding judge had to chuckle. Worse, many of the technology chief's denials and pleas of ignorance were directly refuted by prosecutors with snippets of e-mail that Gates both sent and received.
[55]
Gates later said he had simply resisted attempts by Boies to mischaracterize his words and actions. As to his demeanor during the deposition, he said, "Did I fence with Boies? ... I plead guilty. Whatever that penalty is should be levied against me: rudeness to Boies in the first degree."
[56] Despite Gates's denials, the judge ruled that Microsoft had committed
monopolization and 
tying, and blocking competition, both in violation of the 
Sherman Antitrust Act.
[56]
Appearance in ads
Gates appeared in a series of ads to promote Microsoft in 2008. The first commercial, co-starring 
Jerry Seinfeld, is a 90-second talk between strangers as Seinfeld walks up on a discount shoe store (Shoe Circus) in a mall and notices Gates buying shoes inside. The salesman is trying to sell Mr. Gates shoes that are a size too big. As Gates is buying the shoes, he holds up his discount card, which uses a slightly altered version of his own mugshot of his arrest in 
New Mexico in 1977 for a traffic violation.
[57] As they are walking out of the mall, Seinfeld asks Gates if he has melded his mind to other developers, after getting a yes, he then asks if they are working on a way to make computers edible, again getting a yes. Some say that this is an homage to Seinfeld's own show about "nothing" (
Seinfeld).
[58] In a second commercial in the series, Gates and Seinfeld are at the home of an average family trying to fit in with normal people.
Post-Microsoft
Personal life
Gates married Melinda French on January 1, 1994. They have three children: daughters 
Jennifer Katharine (born 1996) and Phoebe Adele (born 2002) and son Rory John (born 1999).
His 66,000 sq ft (6,100 m
2) estate has a 60-foot (18 m) swimming pool with an underwater music system, as well as a 2,500 sq ft (230 m
2) gym and a 1,000 sq ft (93 m
2) dining room.
[64]
Also among Gates's private acquisitions is the 
Codex Leicester, a collection of writings by
Leonardo da Vinci, which Gates bought for $30.8 million at an auction in 1994.
[65] Gates is also known as an avid reader, and the ceiling of his large home library is engraved with a quotation from 
The Great Gatsby.
[66] He also enjoys playing bridge, tennis, and golf.
[67][68]
Gates was number one on the 
Forbes 400 list from 1993 through to 2007 and number one on 
Forbes list of 
The World's Richest Peoplefrom 1995 to 2007 and 2009. In 1999, his wealth briefly surpassed $101 billion, causing the media to call Gates a "centibillionaire".
[69]Despite his wealth and extensive business travel Gates usually flew 
coach until 1997, when he bought a private jet.
[70] Since 2000, the nominal value of his Microsoft holdings has declined due to a fall in Microsoft's stock price after the 
dot-com bubble burst and the multi-billion dollar donations he has made to his charitable foundations. In a May 2006 interview, Gates commented that he wished that he were not the richest man in the world because he disliked the attention it brought.
[71] Gates has several investments outside Microsoft, which in 2006 paid him a salary of $616,667 and $350,000 bonus totalling $966,667.
[72] He founded 
Corbis, a digital imaging company, in 1989. In 2004 he became a director of 
Berkshire Hathaway, the investment company headed by long-time friend 
Warren Buffett.
[73] In March 2010 Bill Gates was bumped down to the second wealthiest man behind 
Carlos Slim.
Philanthropy
Gates began to appreciate the expectations others had of him when public opinion mounted suggesting that he could give more of his wealth to charity. Gates studied the work of 
Andrew Carnegie and 
John D. Rockefeller, and in 1994 sold some of his Microsoft stock to create the William H. Gates Foundation. In 2000, Gates and his wife combined three family foundations into one to create the charitable 
Bill & Melinda Gates Foundation, which is the largest transparently operated charitable foundation in the world.
[74] The foundation allows benefactors access to information regarding how its money is being spent, unlike other major charitable organizations such as the 
Wellcome Trust.
[75][76] The generosity and extensive philanthropy of 
David Rockefeller has been credited as a major influence. Gates and his father met with Rockefeller several times, and modeled their giving in part on the 
Rockefeller family's philanthropic focus, namely those global problems that are ignored by governments and other organizations.
[77] As of 2007, Bill and Melinda Gates were the second-most generous philanthropists in America, having given over $28 billion to charity.
[78] They plan to eventually give 95% of their wealth to charity.
[79]
The foundation was at the same time criticized because it invests assets that it has not yet distributed with the exclusive goal of maximizing 
return on investment. As a result, its investments include companies that have been charged with worsening poverty in the same developing countries where the Foundation is attempting to relieve poverty. These include companies that pollute heavily, and pharmaceutical companies that do not sell into the developing world.
[80] In response to press criticism, the foundation announced in 2007 a review of its investments, to assess social responsibility.
[81] It subsequently canceled the review and stood by its policy of investing for maximum return, while using voting rights to influence company practices.
[82] The Gates Millennium Scholars program has been criticized for its exclusion of 
Caucasian students.
[83][84]
Gates's wife urged people to learn a lesson from the philanthropic efforts of the Salwen family, which had sold its home and given away half of its value, as detailed in 
The Power of Half.
[85] Gates and his wife invited Joan Salwen to Seattle to speak about what the family had done, and on December 9, 2010, Gates, investor 
Warren Buffett, and 
Mark Zuckerberg (Facebook's CEO) signed a promise they called the "Gates-Buffet 
Giving Pledge", in which they promised to donate to charity at least half of their wealth over the course of time.
[86][87][88]
Recognition
In 1987, Gates was listed as a billionaire in the pages of Forbes' 400 Richest People in America issue, just days before his 32nd birthday. As the world's youngest self-made billionaire, he was worth $1.25 billion, over $900 million more than he'd been worth the year before, when he'd debuted on the list.

[101]
In November 2006, he and his wife were awarded the 
Order of the Aztec Eagle for their philanthropic work around the world in the areas of health and education, particularly in Mexico, and specifically in the program "
Un paĆs de lectores".
[102] In October 2009, it was announced that Gates will be awarded the 
2010 Bower Award for Business Leadership of 
The Franklin Institute for his achievements in business and for his philanthropic work. In 2010 he was honored with the 
Silver Buffalo Award by the 
Boy Scouts of America, its highest award for adults, for his service to youth.

Books and films
To date, Bill Gates has authored two books. 
The Road Ahead, written with Microsoft executive 
Nathan Myhrvold and journalist 
Peter Rinearson, was published in November 1995, and it summarized the implications of the personal computing revolution and described a future profoundly changed by the arrival of a global 
information superhighway. 
Business @ the Speed of Thought was published in 1999, and discusses how business and technology are integrated, and shows how digital infrastructures and information networks can help getting an edge on the competition.
Gates was prominently featured in 
Pirates of Silicon Valley, a 1999 film which chronicles the rise of 
Apple and Microsoft from the early 1970s to 1997. He was portrayed by 
Anthony Michael Hall. officer. Gates's last full-time day at Microsoft was June 27, 2008. He remains at Microsoft as non-executive chairman.
