Bill Gates was born in Seattle, Washington, in 28 October 1955. His full name is William Henry Gates III. His father was a lawyer. The multimillionaire studied in Harvard University (1973-77). With his friend Paul Allen created data processing programs that were sold to businesses. Even when in Harvard, Gates developed a version of the programming language BASIC for the first microcomputer - the MITS Altair. In 1976 he founded in Albuquerque, New Mexico his own business producing data processing software, Microsoft Corporation. His business consisted in creating programs adapted to the needs of the new microcomputers and offering them to the manufacturing businesses, but cheaper than if they had to develop it themselves. In 1979 Microsoft changed its headquarters to Seattle. In 1980 it arrived at an agreement with IBM to supply him an operating system adapted to his new personal computers, the MS-DOS, that would be installed in all the computers of the mark since 1981. In 1983 Gates revolutionised the personal data processing with the introduction of the mouse and of a new graphical interface called to replace the DOS (the Windows). When, in 1986, Microsoft was on the the Market, the actions were quoted so high that Bill Gates became the richer man in the U.S. Microsoft received benefits of US$36,84 trillions in the fiscal year of June 2004, and employed more than 55,000 people in 85 nations. The mission of Microsoft, under the command of Gates, is to grow continuously and to optimise the technology of the software and to develop them more accessible to all the people. Gates is married with Melinda French Gates. They have three children. Gates likes a lot reading and playing golf.
