Steve Jobs, the co-founder of US technology giant Apple, has died at the age of 56.
Jobs died at home in Palo Alto, California surrounded by his family.
His passing comes after a long battle with pancreatic cancer, although no specific cause of death was given.
Jobs is survived by his wife of 20 years, Laurene, and his four children.
Apple fans laid flowers and left candles outside the company’s headquarters in Silicon Valley.
Jobs’ health had been the subject of much speculation in recent years; he had a liver transplant in 2009.
He took medical leave for a third time in January and returned six months later, only to resign as chief executive in August.
Jobs’ personal wealth is estimated at 5.3 billion euros, according to Forbes magazine. It is as yet unclear how his estate will be handled.
Apple said it had “lost a visionary genius” and that “the world has lost an amazing human being”.
The news Apple fans had been dreading came the day after Apple unveiled its updated iPhone, the latest in a procession of devices that shaped technology while Jobs was running the company.
