Few realize that a woman once was a co-owner of the Dodgers with Walter O'Malley. Her name was Mae Smith and by the late 50's she owned about one-quarter of team. Her husband John L. Smith, a famed executive responsible for the mass production of Penicillin at Pfizer, joined the Dodger ownership den in 1944 when the Ebbets family decided they wanted out. In 1950 he passed away and his shares naturally transferred to his wife.
The photo above captures Mrs. Smith with Walt Alston, Carl Erskine and Walter O'Malley on February 25, 1956 in Vero Beach. It is an Associated Press photo that I saw on eBay.
