Lawrence J. Giacoletto

Lawrence Joseph Giacoletto (November 14, 1916, in Clinton, Indiana – October 4, 2004, in Okemos, Michigan) was an American electrical engineer and inventor. He was known among others for his work in the field of semiconductor circuit technology, in particular by the eponymous Giacoletto equivalent circuit for transistors [1][2][3][4][5] (also known as Hybrid-pi model).

Life

Giacoletto studied first at the Rose-Hulman Institute of Technology in Terre Haute. In 1952 he received his doctorate in electrical engineering from the University of Michigan.[6] After his discharge from military service in 1946 Giacoletto began as a development engineer at the RCA Laboratories in Princeton, New Jersey. In 1956 he joined the Ford Motor Company in Dearborn, Michigan, where he served as manager of the Electronics Department of Scientific Labs. Coinciding with this change, he founded the Cooperative Research Institute (CORES).[7] Here he continued his research in the field of vehicle electronics and developed ideas for improving a variety of products. In the late 50s he also worked in the field of home-production of solar energy.[8]

Works

He worked in the development of the RCA color television system,[5] developed the equivalent circuit for transistors[1][2][3][4][5] and invented the homopolar alternator, a device able to convert mechanical energy into electrical energy.[7][9]

He authored or co-authored the following books:

Awards

Giacoletto contributed by the awards Fellow of the IEEE and a Fellow of the American Association for the Advancement of Science. He was a member of the American Physical Society and Sigma Xi and a number of boards. In 2011 it was honored by the Rose-Hulman Institute of Technology with the establishment of an endowed faculty chair in electrical engineering.[7]
