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.
Cadillac Ranch
The group claims to have been given a list of eccentric millionaires in 1972 in San Francisco, identifying Stanley Marsh 3 of Amarillo amongst those who might be able to fund one of their projects and submitted it to him. Marsh's response began "It's going to take me awhile to get used to the idea of the Cadillac Ranch. I'll answer you by April Fool's Day. It's such an irrelevant and silly proposition that I want to give it all my time and attention so I can make a casual judgment of it."
