in 1948, john bardeen, Walter brattain, William schockley jointly invented transistors at bell labs in USA.
Integrated circuits (in many microprocessor integrated circuits) containing many billions of transistors each.
758 Million transistors.
Fourth Generation Computers (which are Microprocessors) were invented through the development of Transistors. Transistors were created by William Shockley, John Bardeen and Walter Brarttain. Therefore, it is hard to tell a specific inventor of the Microprocessor.
There were no transistors in 1947, they weren't invented until 1949.

ICs have been built with as few as two to as many as hundreds of billions of transistors. I believe the first germanium prototype IC built by Kilby may have had only one transistor (it was an integrated circuit not for having many transistors, but because it integrated both resistors and transistors into a single germanium crystal).

millions and more
About 5000.

A modern micro processor has atleast 100 million transistors. The Core i7 920 (D0 stepping) has approximately 781 million transistors.
