General Motors was originally formed by joining several independent companies: the Olds Motor Vehicle Company, owned by Ransom E. Olds, (maker of the [[Oldsmobile]]); Cadillac Automobile Company owned by Henry M. Leland; Buick Motor Company, founded by David Dunbar Buick, and the Oakland Motor Car Co, the original maker of the Pontiac.
One former head of General Motors, John Z. DeLorean, went on to start his own car company, Delorean Motors, and manufactured the [[DeLorean]] car, famed for it's its role in the move "Back to the Future"
