Early Interests

Steven Paul Jobs was born in San Francisco on Feb. 24, 1955, and put up for adoption by his biological parents, Joanne Carole Schieble and Abdulfattah Jandali, a graduate student from Syria who became a political science professor. He was adopted by Paul and Clara Jobs.

The elder Mr. Jobs, who worked in finance and real estate before returning to his original trade as a machinist, moved his family down the San Francisco Peninsula to Mountain View and then to Los Altos in the 1960s.

Mr. Jobs developed an early interest in electronics. He was mentored by a neighbor, an electronics hobbyist, who built Heathkit do-it-yourself electronics projects. He was brash from an early age. As an eighth grader, after discovering that a crucial part was missing from a frequency counter he was assembling, he telephoned William Hewlett, the co-founder of Hewlett-Packard. Mr. Hewlett spoke with the boy for 20 minutes, prepared a bag of parts for him to pick up and offered him a job as a summer intern.

Mr. Jobs met Mr. Wozniak while attending Homestead High School in neighboring Cupertino. The two took an introductory electronics class there.

The spark that ignited their partnership was provided by Mr. Wozniak’s mother. Mr. Wozniak had graduated from high school and enrolled at the University of California, Berkeley, when she sent him an article from the October 1971 issue of Esquire magazine. The article, “Secrets of the Little Blue Box,” by Ron Rosenbaum, detailed an underground hobbyist culture of young men known as phone phreaks who were illicitly exploring the nation’s phone system.

Mr. Wozniak shared the article with Mr. Jobs, and the two set out to track down an elusive figure identified in the article as Captain Crunch. The man had taken the name from his discovery that a whistle that came in boxes of Cap’n Crunch cereal was tuned to a frequency that made it possible to make free long-distance calls simply by blowing the whistle next to a phone handset.

Captain Crunch was John Draper, a former Air Force electronic technician, and finding him took several weeks. Learning that the two young hobbyists were searching for him, Mr. Draper appeared one day in Mr. Wozniak’s Berkeley dormitory room. Mr. Jobs, who was still in high school, had traveled to Berkeley for the meeting. When Mr. Draper arrived, he entered the room saying simply, “It is I!”

Based on information they gleaned from Mr. Draper, Mr. Wozniak and Mr. Jobs later collaborated on building and selling blue boxes, devices that were widely used for making free — and illegal — phone calls. They raised a total of $6,000 from the effort.

After enrolling at Reed College in 1972, Mr. Jobs left after one semester, but remained in Portland for another 18 months auditing classes. In a commencement address given at Stanford in 2005, he said he had decided to leave college because it was consuming all of his parents’ savings.

Leaving school, however, also freed his curiosity to follow his interests. “I didn’t have a dorm room,” he said in his Stanford speech, “so I slept on the floor in friends’ rooms, I returned Coke bottles for the 5-cent deposits to buy food with, and I would walk the seven miles across town every Sunday night to get one good meal a week at the Hare Krishna temple. I loved it. And much of what I stumbled into by following my curiosity and intuition turned out to be priceless later on.”

He returned to Silicon Valley in 1974 and took a job there as a technician at Atari, the video game manufacturer. Still searching for his calling, he left after several months and traveled to India with a college friend, Daniel Kottke, who would later become an early Apple employee. Mr. Jobs returned to Atari that fall. In 1975, he and Mr. Wozniak, then working as an engineer at H.P., began attending meetings of the Homebrew Computer Club, a hobbyist group that met at the Stanford Linear Accelerator Center in Menlo Park, Calif. Personal computing had been pioneered at research laboratories adjacent to Stanford, and it was spreading to the outside world.

“What I remember is how intense he looked,” said Lee Felsenstein, a computer designer who was a Homebrew member. “He was everywhere, and he seemed to be trying to hear everything people had to say.”

Mr. Wozniak designed the original Apple I computer simply to show it off to his friends at the Homebrew. It was Mr. Jobs who had the inspiration that it could be a commercial product.

In early 1976, he and Mr. Wozniak, using their own money, began Apple with an initial investment of $1,300; they later gained the backing of a former Intel executive, A. C. Markkula, who lent them $250,000. Mr. Wozniak would be the technical half and Mr. Jobs the marketing half of the original Apple I Computer. Starting out in the Jobs family garage in Los Altos, they moved the company to a small office in Cupertino shortly thereafter.

In April 1977, Mr. Jobs and Mr. Wozniak introduced Apple II at the West Coast Computer Faire in San Francisco. It created a sensation. Faced with a gaggle of small and large competitors in the emerging computer market, Apple, with its Apple II, had figured out a way to straddle the business and consumer markets by building a computer that could be customized for specific applications.

Sales skyrocketed, from $2 million in 1977 to $600 million in 1981, the year the company went public. By 1983 Apple was in the Fortune 500. No company had ever joined the list so quickly.

The Apple III, introduced in May 1980, was intended to dominate the desktop computer market. I.B.M. would not introduce its original personal computer until 1981. But the Apple III had a host of technical problems, and Mr. Jobs shifted his focus to a new and ultimately short-lived project, an office workstation computer code-named Lisa.

An Apocalyptic Moment

By then Mr. Jobs had made his much-chronicled 1979 visit to Xerox’s research center in Palo Alto, where he saw the Alto, an experimental personal computer system that foreshadowed modern desktop computing. The Alto, controlled by a mouse pointing device, was one of the first computers to employ a graphical video display, which presented the user with a view of documents and programs, adopting the metaphor of an office desktop.

“It was one of those sort of apocalyptic moments,” Mr. Jobs said of his visit in a 1995 oral history interview for the Smithsonian Institution. “I remember within 10 minutes of seeing the graphical user interface stuff, just knowing that every computer would work this way someday. It was so obvious once you saw it. It didn’t require tremendous intellect. It was so clear.”

In 1981 he joined a small group of Apple engineers pursuing a separate project, a lower-cost system code-named Macintosh. The machine was introduced in January 1984 and trumpeted during the Super Bowl telecast by a 60-second commercial, directed by Ridley Scott, that linked I.B.M., by then the dominant PC maker, with Orwell’s Big Brother.

A year earlier Mr. Jobs had lured Mr. Sculley to Apple to be its chief executive. A former Pepsi-Cola chief executive, Mr. Sculley was impressed by Mr. Jobs’s pitch: “Do you want to spend the rest of your life selling sugared water, or do you want a chance to change the world?”

He went on to help Mr. Jobs introduce a number of new computer models, including an advanced version of the Apple II and later the Lisa and Macintosh desktop computers. Through them Mr. Jobs popularized the graphical user interface, which, based on a mouse pointing device, would become the standard way to control computers.

But when the Lisa failed commercially and early Macintosh sales proved disappointing, the two men became estranged and a power struggle ensued, and Mr. Jobs lost control of the Lisa project. The board ultimately stripped him of his operational role, taking control of the Lisa project away from, and 1,200 Apple employees were laid off. He left Apple in 1985.

“I don’t wear the right kind of pants to run this company,” he told a small gathering of Apple employees before he left, according to a member of the original Macintosh development team. He was barefoot as he spoke, and wearing blue jeans.

That September he announced a new venture, NeXT Inc. The aim was to build a workstation computer for the higher-education market. The next year, the Texas industrialist H. Ross Perot invested $20 million in the effort. But it did not achieve Mr. Jobs’s goals.

Mr. Jobs also established a personal philanthropic foundation after leaving Apple but soon had a change of heart, deciding instead to spend much of his fortune — $10 million — on acquiring Pixar, a struggling graphics supercomputing company owned by the filmmaker George Lucas.

The purchase was a significant gamble; there was little market at the time for computer-animated movies. But that changed in 1995, when the company, with Walt Disney Pictures, released “Toy Story.” That film’s box-office receipts ultimately reached $362 million, and when Pixar went public in a record-breaking offering, Mr. Jobs emerged a billionaire. In 2006, the Walt Disney Company agreed to purchase Pixar for $7.4 billion. The sale made Mr. Jobs Disney’s largest single shareholder, with about 7 percent of the company’s stock.

His personal life also became more public. He had a number of well-publicized romantic relationships, including one with the folk singer Joan Baez, before marrying Laurene Powell. In 1996, a sister, the novelist Mona Simpson, threw a spotlight on her relationship with Mr. Jobs in the novel “A Regular Guy.” The two did not meet until they were adults. The novel centered on a Silicon Valley entrepreneur who bore a close resemblance to Mr. Jobs. It was not an entirely flattering portrait. Mr. Jobs said about a quarter of it was accurate.

“We’re family,” he said of Ms. Simpson in an interview with The New York Times Magazine. “She’s one of my best friends in the world. I call her and talk to her every couple of days.”

His wife and Ms. Simpson survive him, as do his three children with Ms. Powell, his daughters Eve Jobs and Erin Sienna Jobs and a son, Reed; another daughter, Lisa Brennan-Jobs, from a relationship with Chrisann Brennan; and another sister, Patti Jobs.
