Steven Paul Jobs ( February 24, 1955 – October 5, 2011) was an American businessman and visionary widely recognized (along with his Apple business partner Steve Wozniak) as a charismatic pioneer of the personal computer revolution. He was co-founder, chairman, and chief executive officer of Apple Inc. Jobs was co-founder and 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.
In the late 1970s, Apple co-founder Steve Wozniak engineered one of the first commercially successful lines of personal computers, the Apple II series. Jobs directed its aesthetic design and marketing along with A.C. "Mike" Markkula, Jr. and others.
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 Apple Lisa (engineered by Ken Rothmuller and John Couch) and, one year later, of Apple employee Jef Raskin's Macintosh. After losing a power struggle with the board of directors in 1985, Jobs left Apple and founded NeXT, a computer platform development company specializing in the higher-education and business markets.
In 1986, he acquired the computer graphics division of Lucasfilm Ltd, which was spun off as Pixar Animation Studios. He was credited in Toy Story (1995) as an executive producer. He remained CEO and majority shareholder at 50.1 percent until its acquisition by The Walt Disney Company in 2006,making Jobs Disney's largest individual shareholder at seven percent and a member of Disney's Board of Directors. Apple's 1996 buyout of NeXT brought Jobs back to the company he co-founded, and he served as its interim CEO from 1997, then becoming permanent CEO from 2000, onwards, spearheading the advent of the iMac, iTunes, iPod, iPhone, and iPad. In buying NeXT, Apple also "acquire the operating system that became Mac OS X." From 2003, Jobs fought an eight-year battle with cancer, and eventually resigned as CEO in August 2011, while on his third medical leave. He was then elected chairman of Apple's board of directors.
On October 5, 2011, around 3:00 p.m., Jobs died at his home in Palo Alto, California, aged 56, six weeks after resigning as CEO of Apple. A copy of his death certificate indicated respiratory arrest as the immediate cause of death, with "metastatic pancreas neuroendocrine tumor" as the underlying cause. His occupation was listed as "entrepreneur" in the "high tech" business.
