Lawrence P. Fisher was the Fisher brother most closely involved with Cadillac in its early years. In 1916, he joined the Fisher Body Company, which had been formed by two of his brothers in 1908. Larry (as people knew him) was one of four of the seven Fisher brothers who brought Fisher Body Corporation under the General Motors umbrella in 1919. In May 1925, Alfred P. Sloan, then the head of General Motors, appointed Fisher as Cadillac General Manager, an office he retained through 1934. Fisher immediately went to work adding exclusive, custom bodies to the Cadillac range. Thus he oversaw the purchase of the Fleetwood Metal Body Company by the Fisher Body Corporation in September 1925.
