Biographical Notes

Heinz W. Ruegg was born in Zurich, Switzerland, in 1935. He received the Diploma in Electrical Engineering from the Swiss Federal Institute of Technology, Zurich (1959), the M.S. degree from the California Institute of Technology in Pasadena (1961) and the Ph.D. degree from Stanford University in Stanford, California (1966). From 1960 to 1961 he was a Graduate Research Assistant at the California Institute of Technology, working on thin magnetic films. In 1961 he joined Fairchild Semiconductor in Palo Alto, California, and worked on the characterization of Micrologic. With R.H. Beeson he co-authored the 1962 ISSCC paper “New forms of all-transistor logic” that included one of the first published diagrams of the Transistor Transistor Logic (TTL) circuit that formed the workhorse digital IC family of the 1970s. In 1962 he led the development of linear integrated circuits and performed exploratory research on solid-state microwave devices. A 1966 organization chart shows him as a Member of the Technical Staff in the Exploratory Devices Section of the Solid State Physics Department reporting to C. Bittmann. He joined Faselec AG in Zurich, Switzerland, to work on low power circuits for watches in 1967.
