Tim Cook.

CEO of Apple. Tim Cook represents the second generation of leadership in innovative businesses such as Apple and computers in general. After visionaries such as Steve Jobs created a reality to match their visions, people such as Cook—managers and nuts-and-bolts businesspeople—transformed the somewhat unstable corporation into a stable venture able to adapt to changing circumstances while holding on to what made the founder's era so distinct. If Jobs and Steve Wozniak were Apple's prophets, Cook became the discipled leader who preserved the legend.
