Cadillac
Cadillac is among the first automobile brands in the world, second in the United States only to fellow GM marque Buick. The firm was founded from the remnants of the Henry Ford Company in 1902. It was named after Antoine de la Mothe Cadillac, who founded Detroit, Michigan. The Cadillac crest is based on his coat of arms.
Chuck Jordan (automobile designer)
One of his first projects was the Aerotrain, completed when he was 28 years old. He rose to director of design for Cadillac in 1957, being chief designer of the 1959 Cadillac, an epitome of fin design (although it was well underway when he arrived.) He also spent time with GM Europe as head of design for Opel. 
He was vice president of design for General Motors from 1986 to 1992. Only six people, including Harley Earl and Ed Welburn have held the position in GM's history.
