Tim Cook and Steve Jobs couldn’t have been more different, according to the Apple cofounder’s biographer Walter Isaacson.

Jobs was a creative genius who spearheaded the development of Apple’s signature products including the Mac, iPhone, and iPod. But he was also a hothead, known for pushing people to their limits and sometimes creating conflict on purpose in meetings to see if it would yield a better outcome, according to Isaacson.
