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.
Henry Ford
With the help of C. Harold Wills, Ford designed, built, and successfully raced a 26-horsepower automobile in October 1901. With this success, Murphy and other stockholders in the Detroit Automobile Company formed the Henry Ford Company on November 30, 1901, with Ford as chief engineer. In 1902, Murphy brought in Henry M. Leland as a consultant; Ford, in response, left the company bearing his name. With Ford gone, Murphy renamed the company the Cadillac Automobile Company.
