The following timeline details the reports about Apple Inc. Chief Executive Officer Steve Jobs’s health since his cancer diagnosis in 2003. Jobs took another leave of absence today to focus on his health, ceding day-to-day operations to Chief Operating Officer Tim Cook.
October 2003: Jobs is diagnosed with cancer in his pancreas and tries to treat the illness by switching to a special diet to avoid surgery, according to a 2008 article in Fortune magazine citing people familiar with the matter. Apple decides not to tell investors after consulting lawyers, the magazine said.
Aug. 1, 2004: Jobs, then 49, discloses the cancer for the first time, saying he had successful surgery to extract the tumor. The operation removed the cancer in time and he won’t require chemotherapy or radiation, Jobs says. Cook runs the company until Jobs returns to work in September.
June 12, 2005: Jobs talks about his fight with cancer during a commencement speech at Stanford University. He says he was diagnosed about a year earlier and that doctors told him he wouldn’t live longer than six months. The cancer turned out to be treatable with surgery “and I’m fine now,” he says.
June 9, 2008: Jobs, while introducing the iPhone 3G at Apple’s developers’ conference, appears thinner and frail. The company blames a “common bug.”
July 21, 2008: Responding to concerns about Jobs’s appearance, Apple says he has no plans to leave the company and that his health is a private matter. Investors aren’t reassured, and the shares fall 10 percent.
July 23, 2008: The New York Times reports that Jobs has been telling associates and Apple’s board he is cancer-free. Jobs had a surgical procedure earlier in the year to address a problem that contributed to his weight loss, the newspaper reports, citing unnamed people close to the executive.
Sept. 9, 2008: Jobs, introducing new iPod media players at an event in San Francisco, still looks thin. “Reports of my death are greatly exaggerated,” Jobs jokes.
Dec. 16, 2008: Apple says Jobs won’t give his usual speech at the Macworld conference. Jobs had used the forum to introduce new products for 11 straight years.
Jan. 5, 2009: Jobs says he has a hormone imbalance, causing him to lose weight. Jobs vows to remain CEO during treatment. “The remedy for this nutritional problem is relatively simple and straightforward,” Jobs says in an open letter.
Jan. 14, 2009: Jobs gives up day-to-day operations to Cook until June, saying his health problems are more complex than originally thought. Jobs says he will remain involved in major strategic decisions. “I look forward to seeing all of you this summer,” he says in a letter to employees.
June 23: Methodist University Hospital Transplant Institute in Memphis, Tennessee, confirms in a statement that Jobs had a liver transplant and has “an excellent prognosis.”
June 29, 2009: Apple announces Jobs’s return to work. During his absence, Apple share rose 66 percent.
Sept. 9, 2009: Jobs makes his first public appearance since his return to work, introducing new iPod models in San Francisco. He says he was the recipient of a liver transplanted from a young adult who had died in a car crash. “I am back at Apple and loving every minute of it,” he says.
Oct. 20, 2010: Jobs appears on stage to unveil a lighter MacBook Air laptop and a version of the Macintosh operating system called Lion.
Jan. 17, 2011: Jobs, 55, takes another medical leave, telling employees in an e-mail that “I love Apple so much and hope to be back as soon as I can.” Cook, who received total compensation of $59.1 million in fiscal 2010 because of bonuses for filling in for Jobs, is left in charge.
