The answer is a little fuzzy, so let's start with the beginning:
Charles Babbage was the first person to fully design a general-purpose
computing machine. Even though he never built his machine, called the
Analytical Engine, he is considered to be the father of the modern
computer.
After Babbage, there were many calculating machines created for special
purposes, but they weren't really computers because they couldn't be
programmed. The first true computer, called ENIAC, was created by the
United States Military.
The ENIAC was a mainframe computer and was the size of a room. Later,
minicomputers were created. These computers were about the size of a car.
By this time, there were many people working on computers:
- William Shockley invented the transistor, and
- Robert Noyce built the first integrated circuit out of many
transistors.
- Ted Hoff designed the first microprocessor, a general-purpose
integrated
circuit.
- Intel Corporation sold a few generations of microprocessors.
- MITS built the Altair, a microcomputer using Intel's 8080
microprocessor, but the Altair didn't have a programming language until
- Bill Gates and Paul Allen wrote a version of BASIC for it.
- After the Altair, several companies started selling microcomputers.
So, no one person invented the microcomputer. If you would like more
information, here is a timeline
of microcomputer history, and another, more
detailed timeline. I found some of the facts above in this very useful
history of microcomputers.
