David Fullagar earned a MSEE from Cambridge University, England in 1963. He worked for Ferranti in Edinburg, Scotland and in 1965 emigrated to the US to join Transitron. After moving to the Fairchild Semiconductor R&D Laboratory in Palo Alto in 1966 to develop linear (analog) integrated circuits, he designed what became the industry's best selling linear IC, the µA741 operational amplifier. Recruited by Jean Hoerni to Intersil in 1969 as the company's first linear designer, Fullagar went on to manage the European operation and later became vice president of R&D. Together with Jack Gifford and Fred Beck, he co-founded Maxim Integrated Products in 1983 where he served as vice president of R&D and Applications until his retirement in 1999.
