Gates III was born on October 28, 1955, shortly after 9:00 p. He lived in Seattle with his two sisters and father, William H. Gates II, who was a Seattle attorney, and the late Mary Gates, who was a schoolteacher. She was also the chairwoman of the United Way International and a University of Washington regent. While his father was a prominent lawyer, his great-grandfather was a mayor, state legislator, and president of a national bank. .
As a young boy, Bill attended a public elementary school before attending the private Lakeside School in Northern Seattle. It was there where Bill fell in love with computers, and at the age of 13 he began his career in programming computers and personal computer software. The reason why Bill was later transferred to Lakeside was because he was born into a family with a history of business, politics, and community service, so it was no surprise that Bill inherited all those qualities which made it easier for him to quickly surpass all of his peer's in all subjects, including science and math. So it was there at Lakeside that Bill was able to concentrate on computers, which benefited him greatly down the road. Back in the 1960's, computers were too large and costly for Lakeside prep to purchase its own, so instead they raised the money through a fundraiser and bought computer time on a mega computer owned by General Electric. It was there that Bill and his good friend, Paul Allen, and a few other Lakeside students became addicted to this computer. All day and night they would write programs, read computer literature, and do anything else that was computer related.
While they spent all this time working with this computer, problems started to arise with the faculty at Lakeside. They skipped classes, either turned in their homework late or not at all, and they also used up all of the school's computer time in just a short amount of time. But they caught a big break as the Computer Center Corporation opened for business in Seattle in 1968.
