Mintzer, Ethel Dummer, 1895-1938
During the Depression, Ethel Sturges Dummer helped finance several other private studies of adolescents. She and her daughter, Ethel Dummer Mintzer, director of the Francis W. Parker School in San Diego, worked together closely in the promotion of "Boole Blocks," a mathematical teaching aid developed by Mintzer and named after Mary Everest Boole, whose ideas about unconscious behavior are discussed in Ethel Sturges Dummer's Mary E. Boole: A Pioneer Student of the Unconscious (1945).
