Erwin Tomash

Born and raised in Saint Paul, Minnesota, Erwin Tomash graduated from the University of Minnesota with his electrical engineering degree in 1943.[2]

Upon graduating from the University of Minnesota, Tomash joined the U.S. Army Signal Corps,[3] where he worked with radar, and was awarded the Bronze Star for his wartime activities. Following his time with the Army Signal Corps, Tomash served at the Naval Ordnance Laboratory briefly, before joining the Engineering Research Associates. As a research associate, he worked on developing electronic computers, including the ERA 1103 or UNIVAC Scientific. In 1956, he joined Telemeter Magnetic in Los Angeles where he became the company's president. He then oversaw Telemeter Magnetics' design of core memories for computers and in 1962 left Telemeter Magnetic, and co-founded Dataproducts Corporation.[2]

Dataproducts Corporation was co-founded by Erwin Tomash in 1962, and specialized in computer peripherals, with a focus on printers. In 1966, core memory was added to the product line, and due to its resulting expansion, the company relocated to Woodland Hills, Los Angeles, California in 1968.[4] The company acquired Staff Dynamics, a personnel agency, and Uptime, a manufacturer of card readers; it also served as an incubator for Informatics, an early software company. By 1970 the company had become the world's leading independent printer manufacturer. In 1980 Tomash retired and Graham Tyson, already chief operating officer and president, succeeded him as chairman.[5]

In 1987 Erwin Tomash was honored by the IEEE Computer Society, and received the Computer Entrepreneur Award in recognition of his early pioneering work with computer peripherals.[6]

Erwin and his wife Adelle Tomash were instrumental in establishing the Charles Babbage Institute, which honorably named a highly regarded library, archives, and a fellowship program after them, as well as the CBI Tomash computer history reprint series.[7][8]

Erwin and Adelle Tomash, as well as the Tomash Family Foundation, were recognized in a 2009-2010 philanthropy report by the University of California, Santa Cruz (UCSC) as having contributed a gift of $1,000 or more to specific programs at the university.[9]

• Oral history interview with Erwin Tomash. Oral history interview by Robina Mapstone, 14 March and 5 April 1973, Woodland Hills, Calif. Charles Babbage Institute, University of Minnesota. Tomash discusses his work with Engineering Research Associates (ERA), including the firm's management, the roles of William Norris, Frank Mullaney, and Arnold Cohen in ERA, Tomash's development of West Coast marketing for ERA after it became a part of Remington Rand, competition with International Business Machines, the development of Williams tube storage devices and core memory, and the ERA 1103 computer. He also recounts his move to Telemeter Magnetics, later Ampex Computer Products, the formation of Dataproducts Corporation and its subsidiary, Informatics Inc., headed by Walter F. Bauer.
• Oral history interview with Erwin Tomash. Oral history interview by Arthur L. Norberg, 15 May 1983, Los Angeles, California. Charles Babbage Institute, University of Minnesota, Minneapolis. Tomash discusses his career, including employment at Engineering Research Associates (ERA) and the founding of Dataproducts. He begins with his electrical engineering education at the University of Minnesota in the early 1940s and his subsequent entry into the Army Signal Corps as a radar specialist. Tomash recalls his departure in 1956 from Remington Rand to Telemeter Magnetics, where he soon became president. This company manufactured core memory systems and one of the first successful transistor memory systems. Tomash explains how he used the organization he and others had assembled from Telemeter Magnetics to found Dataproducts Corporation in 1962.
