Steven Paul Jobs (1955-) and Apple Computer are names that have long gone together.

Born in the United States to an unknown Egyptian-Arab father, Jobs was adopted soon after birth. After graduating high school, he enrolled in Reed College, dropping out after one semester.

In 1976, 21-year-old Jobs and 26-year-old Steve Wozniak founded Apple Computer Co in the family garage. Jobs revolutionised the industry by popularising the concept of home computers.

By 1984, the Macintosh was introduced. He had an influential role in the building of the World Wide Web. He is also the former CEO of Pixar Animation Studios.

Today, with the iPod and the iPhone, Apple is bigger than ever. Incidentally, Jobs worked for several years at an annual salary of $1. It got him a listing in the Guinness Book as 'Lowest Paid CEO.' He was once gifted a $90 million jet by the company though. And his net worth? More than $5.4 billion.
