Steve Jobs died on Wednesday at the age of 56. Jobs had been battling pancreatic cancer for some years and, in August, left is job at Apple, knowing no doubt that the end was nigh.
Jobs twice put Apple on the computing map. His influence on the development of the Macintosh was mighty enough but, after having been sacked from Apple and later reinstated, Jobs oversaw the development of first the iPod, then the iPhone and latterly the iPad - the success of these products has made Apple the most valuable technology company in the world.
In a statement, U.S. President Barack Obama said: "The world has lost a visionary. And 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."
Jobs was born in San Francisco, California, on February 24 1955. His parents toook one look at hm and had him adopted, a development that no-doubt fostered Jobs' rebelliousness.
He started Apple Computer with friend Steve Wozniak in his adoptive parents' garage in 1976.
He once said: "Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose. You are already naked. There is no reason not to follow your heart."
Jobs died at home in Palo Alto, California, surrounded by his family.
The Guardian has published the full text of a speech Jobs gave at Stanford University in 2005. It says a lot more about the man that all the other sloppy obits you'll read elsewhere today. Give it a go.
