1. Bill Gates is a world-famous person who has done a lot to revolutionize the personal
computer. On Oct. 28. 1955 he was born into a family with rich history in business, politics and community service. When Gates was 31 years old, he became America's youngest billionaire and now his wealth is estimated at 62 billion dollars.
2. From his early school days, he was the school's best mathematician and he had a
photographic memory. His parents recognized his intelligence and decided to enroll him in Lakeside, a private school known for its intense academic environment. This decision had far-reaching effects on Bill Gate's life. For it was at Lakeside that Gates was first introduced to computer.
3. Gate's big break came when he was studying at Harvard University. He'd heard that a
computer company needed software to run its machine with. For six weeks he worked day and night with his colleague Paul Alien together creating \"BASIC\". It turned out to be a success.
4. It was accepted, and so Gates left Harvard and set up his company Microsoft. He then went
on to develop DOS and Windows. Today, four-fifths of the computers in the world run on either DOS or Windows.
5. Gate's company Microsoft now employs more than 48,000 people in 60 countries. Even so,
Gates still admits to getting as much excitement from the technology as he does from running the business side of things.
6. He says, \"I still love technology. I can sit and play with software all night long and read a
science magazine all night long.\"
