On the list of biological parents who gave up children who went on to become famous is Abdulfattah John Jandali, the biological father of Apple genius Steve Jobs.

Like his son, Jandali is a workaholic.

He is vice-president of a Reno casino and has no interest in retirement, according to New York Post writer Georgina Dickinson.

He is 80. And he would love to see Jobs before one of them dies.

"This might sound strange, though, but I am not prepared, even if either of us was on our deathbeds, to pick up the phone to call him," Jandali told Dickenson. "Steve will have to do that, as the Syrian pride in me does not want him ever to think I am after his fortune."
