TitleVadász patent notebook (#416)
AuthorVadász, Leslie L.
Biographical NotesLeslie L. Vadász was born in Budapest, Hungary, in 1936. He received a B.S.E.E. from McGill University in 1961 and completed the Harvard University Advanced Management Program in 1990. He moved to the United States in 1961 where he joined Transitron Corporation, located in Wakefield, Massachusetts. He served on the technical staff of Fairchild from 1964 to 1968 where he was a Senior Engineer in the Circuits and Development Technology Section reporting to R. Foglesong in 1966. In 1968 he was head of the MOS Circuit and Device Technology Section reporting to R. Seeds, Manager of the Digital Integrated Electronics Department where he worked on silicon-gate MOS technology. He joined Intel as the fourth employee in 1968 and remained with the company until retiring in 2003. His roles at Intel included Director of Engineering, General Manager, Microcomputer Components Division, Executive Vice President and member of the Board of Directors.
