CUPERTINO, Calif. — Steve Jobs, the Apple founder and former CEO who invented and masterfully marketed ever-sleeker gadgets that transformed everyday technology, from the personal computer to the iPod and iPhone, has died. He was 56.
Apple announced his death without giving a specific cause.
“We are deeply saddened to announce that Steve Jobs passed away today,” the company said Wednesday in a brief statement.
Mr. Jobs had battled cancer in 2004 and underwent a liver transplant in 2009 after taking a leave of absence for unspecified health problems. He took another leave of absence in January, his third since his health problems began and officially resigned in August.
His family issued a statement in response to his death:
“In his public life, Steve was known as a visionary; in his private life, he cherished his family. We are thankful to the many people who have shared their wishes and prayers during the last year of Steve’s illness; a website will be provided for those who wish to offer tributes and memories.
“We are grateful for the support and kindness of those who share our feelings for Steve. We know many of you will mourn with us, and we ask that you respect our privacy during our time of grief.”
Mr. Jobs started Apple with a high school friend in a Silicon Valley, Calif., garage in 1976, was forced out a decade later and returned in 1997 to rescue the company. During his second stint, it grew into the most valuable technology company in the world.
Cultivating Apple’s countercultural sensibility and a minimalist design ethic, Mr. Jobs rolled out one sensational product after another, even in the face of the late-2000s recession and his own failing health.
He helped change computers from a geeky hobbyist’s obsession to a necessity of modern life at work and home, and in the process he upended not just personal technology but the cellphone and music industries. For transformation of American industry, he has few rivals.
Perhaps most influentially, Mr. Jobs in 2001 launched the iPod, which offered “1,000 songs in your pocket.” Over the next 10 years, its white earphones and thumb-dial control seemed to become more ubiquitous than the wristwatch.
In 2007 came the touch-screen iPhone, joined a year later by Apple’s App Store, where developers could sell iPhone “apps” which made the phone a device not just for making calls but also for managing money, editing photos, playing games and social networking. And in 2010, Jobs introduced the iPad, a tablet-sized, all-touch computer that took off even though market analysts said no one really needed one.
By 2011, Apple had become the second-largest company of any kind in the United States by market value. In August, it briefly surpassed Exxon Mobil as the most valuable company.
President Obama said in a statement Wednesday night that Mr. Jobs was brave enough to think differently, bold enough to believe he could change the world, and talented enough to do it.
“There may be no greater tribute to Steve’s success than the fact that much of the world learned of his passing on a device he invented.”
