Florence Meyer Blumenthal (1875–1930) was an American philanthropist who founded the Fondation franco-américaine Florence Blumenthal (Franco-American Florence Blumenthal Foundation), which awarded the Prix Blumenthal from 1919-1954 to painters, sculptors, decorators, engravers, writers, and musicians — to promote Franco- American relations. For their altruism, Florence Blumenthal and her husband George Blumenthal received the French Legion of Honor in 1929. Both a street as well as a public square in Paris are named in her honor.
