Cadillac
Cadillac was formed from the remnants of the Henry Ford Company. After a dispute between Henry Ford and his investors, Ford left the company along with several of his key partners in March 1902. Ford's financial backers William Murphy and Lemuel Bowen called in engineer Henry M. Leland of Leland & Faulconer Manufacturing Company to appraise the plant and equipment in preparation for liquidating the company's assets. Instead, Leland persuaded the pair to continue manufacturing automobiles using Leland's proven single-cylinder engine. A new company called the Cadillac Automobile Company was established on 22 August 1902, re-purposing the Henry Ford Company factory at Cass Street and Amsterdam Avenue. It was named after French explorer Antoine Laumet de La Mothe, sieur de Cadillac, who had founded Detroit in 1701.
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.
