Young Steve Jobs

Apple co-founder Steve Jobs died on October 5, 2011, of pancreatic cancer at the age of 56. In a statement released then, Apple said Jobs' "brilliance, passion and energy were the source of countless innovations that enrich and improve our lives. The world is immeasurably better because of Steve."

Jobs co-founded Apple with Steve Wozniak in 1976 but left the company in 1985, according to the Library of Congress. Jobs returned in 1996 and served as Apple CEO until 2011, when he resigned two months before his death.
