An African American singer, Marian Anderson found more success and fame in Europe than America until in 1939 the DAR (Daughters of the American Revolution) refused to allow her to sing in their Constitution Hall in Washington, DC. In part because of the public attention brought by this incident, Marian Anderson became one of the best-known African American women of the 20th century.
