AppleCorporation founder, dumped in the late 80's, founded NeXT which produced a great cubical computer called the NeXTBox and an OS called NeXTStep. The window manager AfterStep is heavily based on NeXT. NeXT went bust, Apple almost went the same way, so they hired Jobs again who turned the company around completely with the releases of things like the iMac and MacOSX.

From the Apple website:

Steve Jobs is the CEO of Apple, a leader in personal computers which he co-founded in 1976, and Pixar, the Academy-Award-winning animation studios which he co-founded in 1986.

Apple ignited the personal computer revolution in the 1970s with the Apple II, and reinvented the personal computer in the 1980s with the Macintosh. Today, Apple remains committed to creating the best personal computers in the world, and its hardware and software products are widely regarded as being the most innovative in the industry.

Pixar has created three of the most successful and beloved animated films of all time: Toy Story (1995), A Bug's Life (1998), Toy Story 2 (1999) and Monsters Inc. (2001). Pixar's four films have together earned more than $1.5 billion box office receipts worldwide. Pixar's next film, Finding Nemo, will be released in summer 2003.

Steve grew up in the apricot orchards which later became known as Silicon Valley, and still lives there with his wife and three of his four children.
