Only a handful of artists can claim that they have influenced generations of performers, as well as having fought in the Civil Rights movement, and fighting to break down the barriers of racism against black artists in America even before that movement started: Lena Horne is one of those artists. She died on Sunday in New York-Presbyterian Hospital.
