American computer designer and entrepreneur Steve Jobs founded Apple Computers with Steve Wozniak, setting up shop in his parents' garage. One of the most successful college drop-outs ever, Jobs changed the world of technology forever. Because of personality clashes, Steve Jobs left Apple to set up another company and also became the major investor in Pixar, later becoming its CEO. Jobs' stock in Pixar, a maker of computer-generated full-length animated movies, has enabled him to join the Billionaire Club. In 1997, Jobs rejoined Apple as its interim CEO. At that point, the company was in free fall, with many predicting its imminent demise. Jobs is credited with singlehandedly reviving Apple. The highly successful I-Mac and innovative I-Books were developed under his direction.
