Interesting tangential fact: Ford Motor Company was not Henry Ford's first automotive company. He previously started the (less descriptive) Henry Ford Company (his second automotive venture) which was bought and turned into the Cadillac brand.[1] Cadillac would eventually become General Motors.

Combine that with the split between the Dodge brother investors, and all the Detroit "Big Three" manufacturers can be traced to Henry Ford. [2]
