We know he was driven, ambitious, demanding and a technical genius. But what was Steve Jobs like as a man?
How did his temper stack up to his sense of humour? Was he fair-minded or judgemental? Did he make friends easily and did he keep them?

We do know that, outside of his corporate duties, he was an intensely private man.
Jobs had a complex personality and to dismiss it as arrogance appears to be selling him short. Rick Lucas, managing partner with Lucas Design in the 1980s, described him as soft-spoken and gracious.
"In my entire experience with Steve I found him to be soft-spoken and gracious to the point of being deferential," Lucas, who worked alongside Jobs for several months, recalled.
"What others have characterised as bluntness struck me as simply an efficiency of words. Each word spoken by Steve furthered an objective."
Estranged father hoped for just a coffee with Jobs
Born in San Francisco on February 24, 1955, Jobs was adopted soon after birth by accountant Clara and machinist Paul Jobs. It was only later in life that he discovered the identities of his estranged parents - graduate student Joanne Simpson and Syrian Muslim Abdulfattah John Jandali, who left the US at age 18 but is now the vice president of a casino in Reno, Nevada.

Jobs never met his biological father, despite Jandali telling The Sun in a rare interview after Jobs stepped down as Apple CEO in August that "I live in hope that before it is too late he will reach out to me".
"Even to have just one coffee with him just once would make me a very happy man," said Jandali, who bears a striking resemblance to his son.
