James M. Fosgate (born c. 1945 in Indianapolis, Indiana) is an American inventor, engineer and businessman. The self-taught son of a television and radio repairman, Fosgate invented the first car amplifier in 1973 and founded Fosgate Electronics, now called Rockford Fosgate. Since his departure from Rockford Fosgate in 1981, Fosgate has remained active in the audio world, running Fosgate Laboratories and leading the team that created Dolby Pro Logic II.[1] He received a special Emmy for that invention.[2][3][4][5] Fosgate was also the developer of one of the finest quadraphonic decoders, the TATE II 101A (see the SQ section of the article pointed to by the previous link, for details), in collaboration with Peter Scheiber and Martin Willcocks, which was superseded by his 3601 decoder.
