Charles Oscar Finley (February 22 1918 - February 19 1996), born in Ensley, Alabama, was an American businessman who is best remembered for his tenure as the flamboyant owner of the Oakland Athletics Major League Baseball team. Finley was a semi-pro baseball player in Indiana who had his career cut short in 1946 by a bout with tuberculosis that nearly killed him. Finley then made his fortune in the insurance business, being among the first to write group medical insurance policies for those in the medical profession.
