Number 34: Birth of the iPod... and more.As an MIT doctoral student in the early 1950s, Robert Noyce was known as Rapid Robert for his quick mind. As a cofounder of Intel Corp., he was known as the Mayor of Silicon Valley. A mentor to Apples Steve Jobs, Noyce is one of those credited as the inventor of the first practical integrated circuit, a.k.a. the microchip which made modern-day computers possible. Without that, no iPod.
