Fascinating facts about Ted Hoff inventor of the microprocessor in 1968.

M.E. "Ted" Hoff
AT A GLANCE:

Ted Hoff's knowledge of computers (then still very large machines) allowed him to design the computer-on-a-chip microprocessor (1968), which came on the market as the Intel 4004 (1971), starting the microcomputer industry.

The Story:
Dr. Marcian Edward "Ted" Hoff, Jr. was born October 28, 1937 at Rochester, New York. He received a BEE (1958) from Rensselear Polytechnic Institute in Troy, NY. During the summers away from college he worked for General Railway Signal Company in Rochester where he made developments that produced his first two patents. He attended Stanford as a National Science Foundation Fellow and received a MS (1959) and Ph.D. (1962) in electrical engineering. He joined Intel in 1968.

As a researcher for the Intel Co, who were developing an integrated circuit for a Japanese manufacturer of desk-top calculators. With a knowledge of computers (then still very large machines) he designed the computer-on-a-chip microprocessor (1968), which came on the market as the Intel 4004 (1971), starting the microcomputer industry.

In 1980, he was named the first Intel Fellow, the highest technical position in the company. He spent a brief time as VP for Technology with Atari in the early 1980s and is currently VP and Chief Technical Officer with Teklicon, Inc. Other honors include the Stuart Ballantine Medal from the Franklin Institute. Inducted into National Inventors Hall of Fame in 1996 for his invention of the Microprocessor Concept and Architecture.
