In an interview with “60 Minutes” that aired Sunday evening, Steve Jobs’ biographer Walter Isaacson revealed that the Apple founder had actually met his biological father face-to-face once – even though neither man had known at the time.  The extremely private Jobs sought out his biological mother and sister in the mid 1980s, saying that he felt something was missing from his life.  He became very close with his biological sister, novelist Mona Simpson.  But, after learning a bit about his father, Abdulfattah Jandali, who had left his mother when Mona was still young, he decided against it.  “I learned a little bit about him, and I didn’t like what I learned,” Jobs says in new audio recordings released by Isaacson.  “I asked her to not tell him that we’d ever met and not tell him anything about me.”  But, as it turns out they had already met, even though neither man realized it.  When Mona Simpson tracked down Jandali, he told her about a restaurant he used to manage in Silicon Valley that was very popular.  “Everybody used to come there… even Steve Jobs used to come there,” he told her.  “He was a great tipper.”  Simpson was shocked, but didn’t reveal that Jobs was Jandali’s son.  “I remember meeting the owner who was from Syria, and it was most certainly him, and I shook his hand and he shook my hand and that’s all,” Jobs told Isaacson.  Jandali, now 80, said he sent Jobs’ birthday emails after he found out he was his father, and claims that one time he received a response that just said “Thank you.”
