Florence Dreyfous (October 25, 1868 – September 11, 1950) was an American painter who studied and spent most of her life in New York City.^[1]

Florence Dreyfous was born in New York City on October 25, 1868 to Alida Gomez Dreyfous (1833–1907) and her husband Joseph A. Dreyfous (1832–1891), both of Sephardic Jewish ancestry.^[2] The family would also include daughters—Adele (1859–1879) and Gertrude (1862–1949)—and son Walter (1861–1924). Through their mother, the family would become involved in litigation against a distant relative, Horatio Gomez, who administered a family estate beginning in 1865, but never gave other family members and accounting and also entered into various below-market long-term leases, so a court appointed a referee to investigate his administration in 1891.^[3]

Dreyfous studied at the Chase School of Art and with Robert Henri at the Henri School of Art, as well as with contemporary miniaturist Theodora W. Thayer(1868–1905).^[4]

In 1903 and 1904, Dreyfous exhibited at the Pennsylvania Academy of the Fine Arts.^[4] She also exhibited two of her watercolors, A boy and Mildred, at the landmark 1913 International Exhibition of Modern Art.^[5] Between 1916 and 1932, Dreyfous exhibited at the MacDowell Club, Society of Independent Artists, Morton Gallery in New York, Salons of America and the Opportunity Gallery, all in New York.^[4] In November and December 1921, a watercolor exhibition at the Brooklyn Museum of Art also included her work.^[6]

Dreyfous died September 11, 1950, and is buried with her parents and siblings at historic Beth Olom cemetery^[7] in Queens County, New York.
