The Tale of Two Fins

GM designers were serious in their pursuit of provocative styling to woo war-weary customers. To diminish the visual bulk of Cadillac’s pre-war designs, Earl insisted that both the front and rear fenders be separated from the main body to mimic the muscularity of a crouching animal. (Earl, a talker and hand waver, never placed pen to paper.) To finish the 1948 Cadillac’s long flowing side sweeps, Hershey topped rear fenders with fillips containing taillamps. Inevitably, they were nicknamed tailfins.

Earl later told a newspaper reporter, “When I saw the P-38 rudders sticking up, it gave me an idea for use after the war. But when we introduced fins, we almost started a war within the corporation.”

In fact, Earl, along with other GM heads, had mixed emotions about the fins and he instructed Hershey to pare them off the clay models. But when GM president Charles Wilson, Cadillac chief engineer Ed Cole, general manager John Gordon, and design chief Bill Mitchell all voiced support, Earl reluctantly joined the yea team. When they finally reached the street, fins were deemed a stroke of genius and accessory shops all over the country invented ways to add Cadillac’s tail blips to Chevies and Oldsmobiles.
