7. Read the biography of Bill Gates:

BILL GATES -THE FOUNDER OF MICROSOFT

William Henry Gates was born in Seattle, Washington, in 1955.

He is an American business executive, chairman and chief executive officer of the Microsoft Corporation. Gates was the founder of Microsoft in 1975 together with Paul Alien, his partner in computer language development. While attending Harvard in 1975, Gates together with Alien developed a version of the BASIC computer programming language for the first personal computer.

In the early 1980s, Gates led Microsoft's evolution from the developer of computer programming languages to a large computer software company. This transition began with the introduction of MS-DOS, the operating system for the new IBM Personal Computer in 1981. Gates also led Microsoft towards the introduction of application software such as the Microsoft Word processor.

Much of Gates' success is based on his ability to translate technical visions into market strategy. Although Gates has accumulated great wealth from his holdings of Microsoft stock, he has been known as a tough competitor who seems to value winning in a competitive environment over money. Gates still continues to work personally in product development at Microsoft.
