Philip T. Clark

Clark was hired by a General Motors exec to work on the 1964 Futurama cars for the New York World Show. Working in GM Special Designs, he had a hand in the designs that Larry Shinoda made for the Chevrolet Corvair show cars.

Clark had been conceptualizing the Mustang design in varied forms for years before the final car was produced. His drawing of the Mustang Coupe, or Fastback can be seen signed by him, in the Spring 1963 MotorBook Magazine. The Mustang name was kept under wraps with the code name "Allegro" assigned to the entire project. Allegro was a musical term and Clark and all of the designers he worked with were involved with various musical instruments. This gave the young group who originally were with GM a way to speak about the Mustang project in a code that no one to this day can decipher except for the original designers.

After being released from GM in March 1962, Clark joined Ford in late-April 1962 to work on special projects. Clark's important design role was in creating the mid-engine designs for the Mustang I concept car that later made it up to the executives and met their approval.

Philip Thomas Clark (1935–1968) was an American automotive designer who worked for both General Motors and Ford, and was responsible for ground-breaking designs such as the Ford Mustang and the Ford Capri.

Born in October 27, 1935 in Iowa, Clark and his family moved to Nashville Tennessee in 1942. He was interested in music early in life, and later received a scholarship to Vanderbilt University to begin a medical career, which he abandoned due to the extreme hours required and the worsening of an unknown illness. Clark was apprenticed in aerodynamics with Avco Aviation where his father was the Vice President of Avco and his father-in-law was also a machinist. Clark had been training as an engineer for Avco before he became ill with urological issues and decided that transportation design would be a better fit for his health. Joining Sears, Clark turned to art and advertising, teaching himself using the art course offered by mail.
