Florence Edith Wolf Dreyfuss (March 31,1872 – May 12, 1950) was an executive in Major League Baseball who owned the Pittsburgh Pirates franchise from 1932 to 1946.

Florence Edith Wolf, a native of Louisville, Kentucky, met Barney Dreyfuss on a train to Cincinnati in 1892.

[1] in the late 19th century, Barney bought into the Louisville Colonels baseball team, eventually moving into ownership of Pittsburgh.

Florence, now majority owner of the Pirates, urged her son-in-law, William Benswanger, to take over as president and operating head of the franchise.

Benswanger ran the team until it was sold in 1946, ending the Dreyfuss-Benswanger family's half-century in baseball.
