Steve Jobs, Isaacson’s biography makes clear, was a complicated and exhausting man. “There are parts of his life and personality that are extremely messy, and that’s the truth,” Powell tells Isaacson. “You shouldn’t whitewash it.” Isaacson, to his credit, does not. He talks to everyone in Job’s career, meticulously recording conversations and encounters dating back twenty and thirty years. Jobs, we learn, was a bully. “He had the uncanny capacity to know exactly what your weak point is, know what will make you feel small, to make you cringe,” a friend of his tells Isaacson.

Jobs gets his girlfriend pregnant, and then denies that the child is his. He parks in handicapped spaces. He screams at subordinates. He cries like a small child when he does not get his way. He gets stopped for driving a hundred miles an hour, honks angrily at the officer for taking too long to write up the ticket, and then resumes his journey at a hundred miles an hour. He sits in a restaurant and sends his food back three times. He arrives at his hotel suite in New York for press interviews and decides, at 10 P.M., that the piano needs to be repositioned, the strawberries are inadequate, and the flowers are all wrong: he wanted calla lilies. (When his public-relations assistant returns, at midnight, with the right flowers, he tells her that her suit is “disgusting.”) “Machines and robots were painted and repainted as he compulsively revised his color scheme,” Isaacson writes, of the factory Jobs built, after founding NeXT, in the late nineteen-eighties. “The walls were museum white, as they had been at the Macintosh factory, and there were $20,000 black leather chairs and a custom-made staircase... He insisted that the machinery on the 165-foot assembly line be configured to move the circuit boards from right to left as they got built, so that the process would look better to visitors who watched from the viewing gallery.”
