A new biography of former Apple (NASDAQ: AAPL) CEO Steve Jobs was released this week and, according to The San Francisco Chronicle, is more accurate of Jobs’ personality than his original biographer Walter Isaacson. The new biography, “Becoming Steve Jobs,” was written by Wall Street Journal and Fortune reporter Brent Schlender, according to The San Francisco Chronicle, who reported on Jobs for many years. “I thought the Isaacson book did him a tremendous disservice,” Apple CEO Tim Cook says in “Becoming Steve Jobs,” according to The San Francisco Chronicle. “It was just a rehash of a bunch of stuff that had already been written, and focused on small parts of his personality. You get the feeling that (Steve’s) a greedy, selfish egomaniac. It didn’t capture the person.” Representatives from Apple have said this biography holds truer to Jobs’ personality than the former, with many endorsing its release and providing positive feedback. “Yes, he was very passionate about things, and he wanted things to be perfect,” Cook says about Jobs in the book, according to The San Francisco Chronicle. “And that was what was great about him. A lot of people mistook that passion for arrogance. He wasn’t a saint. I’m not saying that. None of us are. But it’s emphatically untrue that he wasn’t a great human being, and that is totally not understood.”
