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, creation 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.[6] 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,[7] making Jobs Disney's largest individual shareholder at seven percent and a member of Disney's Board of Directors.[8][9]In 1996, NeXT was acquired by Apple. The deal brought Jobs back to the company he co-founded, and provided Apple with the NeXTSTEP codebase, from which the Mac OS X was developed."[10] Jobs was named Apple advisor in 1996, interim CEO in 1997, and CEO from 2000 until his resignation. He oversaw the development of the iMac, iTunes, iPod, iPhone, and iPad and the company's Apple Retail Stores.[11]In 2003, Jobs was diagnosed with a rare form of pancreatic cancer. Though it was initially treated, Jobs reported of a hormone imbalance, underwent a liver transplant in 2009, and appeared progressively thinner as his health declined.[12] In August 2011, during his third medical leave, Jobs resigned as CEO, but continued to work for Apple as Chairman of the Board until his death.On October 5, 2011, he died in his Palo Alto home, aged 56. His death certificate listed 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.[13] Early life and educationSteven Paul Jobs was born in San Francisco on 24 February 1955, to two university students, Joanne Carole Schieble and Syrian born Abdulfattah "John" Jandali (Arabic: ), who were both unmarried at the time.[14] He was adopted at birth by Paul Reinhold Jobs (19221993) and Clara Jobs (19241986). Clara's maiden name was Hagopian.[15] When asked about his "adoptive parents," Jobs replied emphatically that Paul and Clara Jobs "were my parents."[16] He later stated in his authorized biography that they "were my parents 1,000%."[17] His biological parents subsequently married (December 1955), had a second child Mona Simpson in 1957, and divorced in 1962.[17]The Jobs family moved from San Francisco to Mountain View, California when Steve was five years old.[1][2] Paul and Clara later adopted a daughter, Patti.
