Company Overview Visit teradyne.com website

Teradyne is a supplier of automatic test equipment. The company develops all types of semiconductors from memory to microprocessors. Teradyne was founded in 1960 by Peter Teravainen and three associates in Massachusetts, USA, along with additional funds contributed by venture capitalist Georges Doriot who had helped start the Boston Venture Company (later known as American Research and Development Corporation).

Teradyne can trace its roots to Automatic Radio Manufacturing, which it purchased after ten years of ownership under ARD. This company later became Peregrine Electronics.

By 1970, revenues had increased sixfold; employee numbers had risen from 100 to over 1000 people; and there were offices in Paris (France), MunichGermany), Singapore and Sydney (Australia).

In 1974, Teradyne went public on the New York Stock Exchange. In 1977, it established a European subsidiary in Munich and another in Singapore.

In 1983, Teradyne released a semiconductor memory testing machine called "Jaws", which was capable of testing 16-bit memory devices, a major advance over existing testers designed for 8-bit devices.

In 1984, Teradyne diversified by purchasing Dataproducts Corporation (DCP), a large developer and manufacturer of automated test equipment. During fiscal 1985 revenues from DCP were $52 million -- 33% of total company revenues that year. In 1990 this contribution was 82%.

The name changed from Peregrine to Teradyne in 1986.
