Biographical Notes

Dov Frohman-Bentchkowsky was born to Polish Jewish refugees in Amsterdam, Holland, in 1939. He was raised in hiding during the war and emigrated to Israel in 1949. He received a B.Sc. degree in electrical engineering in 1963 from the Israeli Institute of Technology, Haifa, and an M.S. and Ph.D. from University of California, Berkeley. Frohman joined the Fairchild Semiconductor, R&D Laboratory, located in Palo Alto in 1965. A 1966 organization chart lists him as an Engineer B reporting to R. Fogelsong, head of the Circuits and Development Technology Section of the Digital Integrated Electronics Department, led by R. Seeds. In 1968 he reported to L. Vadasz in a new MOS Circuit and Device Technology Dept. He joined Intel Corporation in 1969 where he developed Intel’s first EPROM in 1970. He returned to Israel in 1974 where he established a design center and taught at Hebrew University. In 1985 Frohman was appointed general manger of Intel Israel and remained until his retirement in 2001.
