STEVE JOBS

Steven P. Jobs, the visionary co-founder of Apple who helped usher in the era of personal computers and then led a cultural transformation in the way music, movies and mobile communications were experienced in the digital age, died Wednesday. He was 56.
                The death was announced by Apple, the company Mr. Jobs and his high school friend Stephen Wozniak started in 1976 in a suburban California garage. A friend of the family said the cause was complications of pancreatic cancer.

Mr. Jobs had waged a long and public struggle with the disease, remaining the face of the company even as he underwent treatment, introducing new products for a global market in his trademark blue jeans even as he grew gaunt and frail.

He underwent surgery in 2004, received a liver transplant in 2009 and took three medical leaves of absence as Apple’s chief executive before stepping down in August and turning over the helm to Timothy D. Cook, the chief operating officer. When he left, he was still engaged in the company’s affairs, negotiating with another Silicon Valley executive only weeks earlier.
