Shocking news just received on my Iphone 4 courtesy of the AP app. I am shocked because I thought he was taking time off to fully recover and come back. 
Steven Paul “Steve” Jobs (February 24, 1955 – October 5, 2011) was an American entrepreneur and inventor. He was co-founder, chairman, and chief executive officer of Apple Inc. Jobs also previously served as chief executive of Pixar Animation Studios; he became a member of the board of directors of The Walt Disney Company in 2006, following the acquisition of Pixar by Disney. He was credited in Toy Story (1995) as an executive producer.
In the late 1970s, Jobs, with Apple co-founder Steve Wozniak, Mike Markkula, and others, designed, developed, and marketed one of the first commercially successful lines of personal computers, the Apple II series. In the early 1980s, Jobs was among the first to see the commercial potential of Xerox PARC’s mouse-driven graphical user interface, which led to the creation of the Macintosh. After losing a power struggle with the board of directors in 1985, Jobs resigned from Apple and founded NeXT, a computer platform development company specializing in the higher-education and business markets. Apple’s subsequent 1996 buyout of NeXT brought Jobs back to the company he co-founded, and he served as its CEO from 1997 until 2011. In 1986, he acquired the computer graphics division of Lucasfilm Ltd which was spun off as Pixar Animation Studios.[17] He remained CEO and majority shareholder at 50.1% until its acquisition by The Walt Disney company in 2006.[18] Consequently Jobs became Disney’s largest individual shareholder at 7% and a member of Disney’s Board of Directors.
