Helen Kane is, if known at all, is best known for her influence in the creation of an international animation superstar. Caricaturing her likeness, along with Clara Bow, Fleischer animator Grim Natwick created Betty Boop. However, she was an incredible singer and entertainer during the heyday of the flappers. She was on top of the world until the Great Depression. After that, she was relegated to playing in nightclubs until her death in 1966. During the early thirties, Helen Kane sued the Fleischer's for the unfair competition, and I believe copyright infringement, but the judge ruled against her, saying Kane couldn't prove she invented her style of singing. Enjoy.
