Who's who at Apple

Tim Cook (CEO)

Who is he?
At the fairly ripe old age of 51, Steve Jobs' successor is a fitness nut and reportedly sends emails at 4:30 in the morning, presumably after a long run to gear himself up for another day in charge of the world's most coveted tech company.

Why he matters
Cook single-handedly pulled Apple out of a manufacturing slump in the late 90s and helped Apple reduce inventory levels and streamline its supply chain. The result? A company that can announce a new iPhone one day and deliver it to your hands in a matter of weeks – an Apple tradition.
