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.
Owen Nacker
He was recruited in 1926 by Cadillac general manager Lawrence P. Fisher (October 19, 1888 in Norwalk, Ohio – September 3, 1961 in Detroit, Michigan) to work at the Cadillac Division of General Motors Corporation (GM). Nacker became head of engine development. He designed a 45 degree Overhead valve V-8 with an aluminum crankcase, five main bearings, counterweighted crankshaft with a front vibration damper and timing chain driving the generator. Cylinder blocks included cast nickel-iron liners extending into the crankcase with cast iron heads. This was the engine for Cadillac Division's new 1927 LaSalle companion model.
