Michael Saul Dell (born February 23, 1965) is an American business magnate and the founder and chief executive officer of Dell Inc. He is one of the richest people in the world, with a net worth of US$14 billion in 2010.
The son of an orthodontist and a stockbroker, Dell attended Herod Elementary School in Houston, Texas. In a bid to enter business early, he applied to take a high school equivalency exam at age eight. In his early teens, he invested his earnings from part-time jobs in stocks and precious metals.
Dell purchased his first calculator at age seven and encountered his first teletype machine in junior high, which he programmed after school. At age 15, after playing with computers at Radio Shack, he got his first computer, an Apple II, which he promptly disassembled to see how it worked. Dell attended Memorial High School in Houston, selling subscriptions to the Houston Post in the summer. While making cold calls, Dell observed that newlyweds and people moving into new homes were most likely to buy a subscription. He targeted this demographic group by collecting names from marriage and mortgage applications. Dell earned $18,000 that year, exceeding the annual income of his history and economics teacher.
