It’s up to you to decide where the story of Baby Esther’s erasure begins. In 1930, Betty Boop appeared in the cartoon Dizzy Dishes as an anthropomorphic French poodle. Betty didn’t become human until 1932 when her floppy ears turned into hoop earrings.
It was during this trial that the real Betty Boop was exposed. Theatrical Manager Lou Walton testified that Helen Kane had seen Baby Esther’s act in April, 1928. An act in which Baby Esther sang the song “I Wanna Be Loved By You” with phrases like “boop-boop-a-doop” sung throughout the performance. Just a few weeks later Kane began to “boop” like Baby Esther.
Lou Walton also testified that in 1925 he had personally taught a young Baby Esther her signature scat style. Helen Kane's plan was unraveling.
By the time the trial had taken place, Baby Esther had already passed — the jazz singer had nothing to gain from the revelation. However, Helen Kane’s career was on the decline, and this was an easy way to get back in the public eye.
