Robert Noyce was a co-inventor of integrated circuit along with Jack Kilby. He is also a co-founder of Fairchild Semiconductor and Intel.
Here, he talks about the first times of the integrated circuits. First, there were transistors on germanium semiconductor, then on silicon semiconductor. After that, they put more transistors on a piece of wafer. There apeared problems like impurity at the surface of semiconductor, power dissipation, costs and so on, but by solving these problems, the number of transistors per silicon chip increased considerably. Here appeared again the notion of tyranny of numbers. Then, they made unique circuits that could apply for a wide variety of applications. Controllers and processors appeared.
Below, there is a video clip with Robert Noyce talking about these things:
And here you can find a videoclip about more of his life:
