While attending Harvard University, Bill Gates developed a version of the programming language BASIC. Gates' version of BASIC was for MITS Altair, the first microcomputer. He did not write any other programming languages.
Gates started attending Harvard in 1973. He founded Microsoft two years later with his friend Paul Allen. During his junior year at Harvard, Gates decided to leave school behind and pursue his passion and his company. Microsoft's mission was always to provide an affordable way for individuals and families to enjoy personal technology. He knew at an early age that he liked computers, and he began programming at the age of 13.
