Bill Gates, in full William Henry Gates III, (born October 28, 1955, Seattle, Washington, U.S.), American computer programmer and entrepreneur who cofounded Microsoft Corporation, the world’s largest personal-computer software company. Gates wrote his first software program at the age of 13. In high school he helped form a group of programmers who computerized their school’s payroll system and founded Traf-O-Data, a company that sold traffic-counting systems to local governments. In 1975 Gates, then a sophomore at Harvard University, joined his hometown friend Paul G. Allen to develop software for the first microcomputers. They began by adapting BASIC, a popular programming language used on large computers, for use on microcomputers. With the success of this project, Gates left Harvard during his junior year and, with Allen, formed Microsoft. Gates’s sway over the infant microcomputer industry greatly increased when Microsoft licensed an operating system called MS-DOS to International Business Machines Corporation—then the world’s biggest computer supplier and industry pacesetter—for use on its first microcomputer, the IBM PC (personal computer). After the machine’s release in 1981, IBM quickly set the technical standard for the PC industry, and MS-DOS likewise pushed out competing operating systems. While Microsoft’s independence strained relations with IBM, Gates deftly manipulated the larger company so that it became permanently dependent on him for crucial software. Makers of IBM-compatible PCs, or clones, also turned to Microsoft for their basic software. By the start of the 1990s he had become the PC industry’s ultimate kingmaker.

Early Life & Family

Bill Gates was born in Seattle, Washington on October 28, 1955. He is the son of William H. Gates Sr.[b] (1925–2020) and Mary Maxwell Gates (1929–1994). His ancestry includes English, German, and Irish/Scots-Irish. His father was a prominent lawyer, and his mother served on the board of directors for First Interstate BancSystem and the United Way of America. Gates's maternal grandfather was J. W. Maxwell, a national bank president. Gates has an older sister Kristi (Kristianne) and a younger sister Libby. He is the fourth of his name in his family but is known as William Gates III or "Trey" (i.e., three) because his father had the "II" suffix. The family lived in the Sand Point area of Seattle in a home that was damaged by a rare tornado when Gates was seven years old.

Hobbies & Interests

While president and chief software architect at Microsoft, Bill Gates would spend one entire week reading as many papers as he could in a secret cabin in the Pacific Northwest. “I would literally take boxes out to a beach place and sit there for a week reading them day and night and scribbling on them to putting it entirely online,” Gates explained during Microsoft’s CEO Summit a few years back.

Education & Career

With an IQ of 160, Gates is classified as a genius. It's not a surprise to find out he scored 1590 out of 1600 in his college SATs. He dropped out of Harvard University aged 20 and returned over 30 years later to be awarded an honorary Doctor of Laws degree in 2007.

Personal Life

Gates is an avid reader, and the ceiling of his large home library is engraved with a quotation from The Great Gatsby. He also enjoys bridge, tennis and golf. His days are planned for him on a minute-by-minute basis, similarly to the U.S. president's schedule. Despite his wealth and extensive business travel, Gates flew coach (economy class) in commercial aircraft until 1997, when he bought a private jet.

It's hard to imagine what to do with that amount of money, but Gates knows how to make the most of it. While he has some indulgences - like a Washington estate worth $125 million, a private airplane, and a luxury car collection - they only make up a fraction of his massive fortune.
