Achievement

Co-invented the Intel 4004 "computer" on a chip: Intel 4004

Biography

At age 15, he won a trip to Washington, D.C., and a $400 scholarship from the Westinghouse Science Talent Search.

During the summers away from college he worked for General Railway Signal Company in Rochester where he designed two circuits that produced his first two patents.(4) One circuit detected trains through the audio frequencies transmitted along the railway track. Another absorbed energy to protect against lightning.(6)

Entered Stanford as a National Science Foundation Fellow in 1955

Between September 1968 and April 1969, Ted Hoff started to develop a family of chips for a Japanese calculator company. These chips were intended for a calculator that would come out under a brand called Busicom.

When he suggested to the japanese engineers to make better use of the memory by simplifying the functions the Japanese were not interested in making changes. But Bob Noyce told him and Stan Mazur to go ahead and what resulted was a general purpose computer. Ted Hoff also developed the instruction set for that computer what essentially became the instruction set for 4004 microprocessor. Since neither Hoff nor Mazur knew much of CMOS technology it was Federico Faggin to get the chip on silicon in 1971.

The chip had as much power as the ENIAC, which filled 3,000 cubic feet with 18,000 vacuum tubes.

When a headhunter contacted him in early 1983, he was ready for a change and joined Atari as vice president of technology. "Atari was doing some interesting things at the time, like looking at the role computers could play in the home and special graphics kinds of things," he says. But Atari's consumer product, video games, began to slip rapidly about a year after he joined. Warner, which owned Atari, sold it in mid-'84. Hoff was offered a position with the new owner, Commodore, a consumer electronics company that was trying to expand its product line. But he wasn't sure where he would fit in, so he went off on his own.
Gary Summers, who knew Hoff from Atari, offered to work with him. Summers had founded a company called Teklicon, a consulting firm that specializes in supplying technical experts to attorneys dealing in intellectual-property litigation. Hoff started as a consultant but is now a vice president and the chief technologist.
Today, Hoff works on his new house, where he has an electronics lab and a small machine shop, complete with a milling machine and a small metal lathe for turning out prototypes of things.(7)
