and apple has confirmed this as well https://www.apple.com/stevejobs/
Apple co-founder and Chairman Steve Jobs died today, Apple said. He was 56.
Jobs had been suffering from various health issues following the seven-year anniversary of his surgery for a rare form of pancreatic cancer in August 2004. Apple announced in January that he would be taking an indeterminate medical leave of absence, with Jobs then stepping down from his role as CEO in late August.
