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 was among the first to see the commercialpotential of Xerox PARC's mouse-driven graphical user interface, which led to the creation of the Apple Lisa and, one year later, the Macintosh. By introducing the LaserWriter he enabled a revolution called desktop publishing.
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 thehigher-education and business markets.
In 1986, he acquired the computer graphics division of Lucasfilm, which was spun off as Pixar. He was credited in Toy Story (1995) as an executive producer. He served as CEO and 50.1% majority shareholder until Disney bought Pixar in 2006.  Jobs received 7% of Disney shares, and joined the Board of Directors as the largest individual shareholder.
By 1996, Apple had failed to deliver a new operating system, Copland. Gil Amelio turned to NeXT Computer, and the NeXTSTEP platform became the foundation for the Mac OS X.  Jobs returned to Apple as an advisor, and took control of the company as an interim CEO. Jobs brought Apple from near bankruptcy to profitability by 1998. 
As the new CEO of the company, Jobs oversaw thedevelopment of the iMac, iTunes, iPod, iPhone, and iPad, and on the services side, the company's Apple Retail Stores, iTunes Store and the App Store. The success of these products and services, provided several years of stable financial returns, and propelled Apple to become the world's most valuable publicly traded company in 2011. The reinvigoration of the company is regarded by manycommentators as one of the greatest turnarounds in business history.
In 2003, Jobs was diagnosed with a pancreas neuroendocrine tumor. Though it was initially treated, he reported a hormone imbalance, underwent a liver transplant in 2009, and appeared progressively thinner as his health declined. On medical leave for most of 2011, Jobs resigned in August that year, and was electedChairman of the Board. He died of respiratory arrest related to his metastatic tumor on October 5, 2011.
Jobs has received a number of honors and public recognition for his influence in the technology and music industries. He has widely been referred to as "legendary", a "futurist" or simply "visionary", and has been described as the "Father of the Digital Revolution", a"master of innovation", and a "design perfectionist".
Early life and education
Steven Paul Jobs was born in San Francisco on February 24, 1955 to two university students, Joanne Carole Schieble and Syrian-born Abdulfattah "John" Jandali (Arabic: عبدالفتاح جندلي), who were both unmarried at the time. Jandali, who was teaching in Wisconsin when Steve was born, said he had nochoice but to put the baby up for adoption because his girlfriend's family objected to their relationship.
The baby was adopted at birth by Paul Reinhold Jobs (1922–1993) and Clara Jobs (1924–1986), an Armenian American whose maiden name was Hagopian. According to Steve Jobs's commencement address at Stanford, Schieble wanted Jobs to be adopted only by a college-graduate couple....
