Helen Kane
The woman best-known as the inspiration for the cartoon character Betty Boop was also a star in her own right. The tiny, plump Brooklynite was playing vaudeville with the Marx Brothers by the early 1920s, and skyrocketed to stardom in 1928 while singing at the Paramount in Times Square. Interpolating the scat lyrics "Boop-Boop-a-Doop" into the song "I Want to Be Loved By You," Kane invented a whole new style of baby-voiced singing which epitomized the endearing silliness of the Roaring 20s.
