John Bardeen, William B. Shockley, and Walter H. Brattain are collectively known as the fathers of the second generation of computers.

They invented the transistor in 1947, which led to the development of smaller, faster, and more efficient computers.

The fathers of each generation of computers:

1. First generation (Vacuum Tubes): John Atanasoff (invented the first electronic computer, ABC)
2. Second generation (Transistors): John Bardeen, William B. Shockley, and Walter H. Brattain (invented the transistor)
3. Third generation (Integrated Circuits): Jack Kilby (developed the first integrated circuit)
4. Fourth generation (Microprocessors): Ted Hoff and Stanley Mazor (developed the first microprocessor, Intel 4004)
