Bill Gates- Biography.Pdf
William H. Gates Chairman Microsoft Corporation William (Bill) H. Gates is chairman of Microsoft Corporation, the worldwide leader in software, services and solutions that help people and businesses realize their full potential. Microsoft had revenues of US$39.79 billion for the fiscal year ending June 2005, and employs more than 61,000 people in 102 countries and regions. On June 15, 2006, Microsoft announced that effective July 2008 Gates will transition out of a day-to-day role in the company to spend more time on his global health and education work at the Bill & Melinda Gates Foundation. After July 2008 Gates will continue to serve as Microsoft’s chairman and an advisor on key development projects. The two-year transition process is to ensure that there is a smooth and orderly transfer of Gates’ daily responsibilities. Effective June 2006, Ray Ozzie has assumed Gates’ previous title as chief software architect and is working side by side with Gates on all technical architecture and product oversight responsibilities at Microsoft. Craig Mundie has assumed the new title of chief research and strategy officer at Microsoft and is working closely with Gates to assume his responsibility for the company’s research and incubation efforts. Born on Oct. 28, 1955, Gates grew up in Seattle with his two sisters. Their father, William H. Gates II, is a Seattle attorney. Their late mother, Mary Gates, was a schoolteacher, University of Washington regent, and chairwoman of United Way International. Gates attended public elementary school and the private Lakeside School. There, he discovered his interest in software and began programming computers at age 13. -
