"ONCE IN A HUNDRED YEARS" refers to the quote of the great conductor Arturo Toscanini who once told Marian Anderson: "A voice like yours is heard once in a hundred years." Marian Anderson's story continues to inspire people from very different backgrounds and her achievements in overcoming bigotry have secured her a place as a true pioneer internationally and in her home town of Philadelphia, the city of brotherly love. We walk the streets where she lived; talk to the people who knew her, knew her family, and someone she babysat; see where she was educated and went to church; and marvel at how she was able to transcend humble beginnings to sing for tens of thousands of people, and for Presidents and queens on the world's stages.
