EtymologyNamed after Horace H. Rackham (1858-1933), a Detroit lawyer who invested $5,000 in Henry Ford's new venture to build "horseless carriages." Ford bought out minority shareholders (1919), and Rackham's $5,000 turned into $12.5 million on top of the $2 million in dividends he had already been paid.
