Harley Earl, American businessman (b. 1893)
Harley Jarvis Earl (November 22, 1893 – April 10, 1969) was an American automotive designer and business executive. He was the initial designated head of design at General Motors, later becoming vice president, the first top executive ever appointed in design of a major corporation in American history. He was an industrial designer and a pioneer of modern transportation design. A coachbuilder by trade, Earl pioneered the use of freeform sketching and hand sculpted clay models as automotive design techniques. He subsequently introduced the "concept car" as both a tool for the design process and a clever marketing device.

Earl's Buick Y-Job was the first concept car. He started "Project Opel", which eventually became the Chevrolet Corvette, and he authorized the introduction of the tailfin to automotive styling. During World War II, he was an active contributor to the Allies' research and development program in advancing the effectiveness of camouflage.
