From the 2007 Kentucky Derby site:

Women have become commonplace on the Oaks scene as owner and breeders of not only runner, but also winners. In fact, three of the last ten winners were owned by women.

Besides the role of owner, Mary Keim also trained the 1965 winner, her own Amerivan; she is the only woman to have trained an Oaks winner.
