to vote. 2021: Anderson's life and the 1939 Constitution Hall controversy and her subsequent concert at the Lincoln Memorial were the subject of a documentary, Voice of Freedom, that aired as an episode of American Experience on PBS. Marian Anderson Award The Marian Anderson Award was established in 1943 by Anderson after she was awarded the $25,000 from The Philadelphia Award in 1940 by the city of Philadelphia. Anderson used the award money to establish a singing competition to help support young singers. The prize fund was exhausted in due course and disbanded in 1976. In 1990, the award was re-established and has dispensed $25,000 annually. In 1998, the Marian Anderson Award prize money was restructured to be given to an established artist, not necessarily a singer, who exhibits leadership in a humanitarian area.
