Real name: Doris Mary Ann Von Kapplehoff. Was dubbed Doris Day when a song
she sang became popular
yet she remained relatively obscure
, so people only remembered her first name and the fact that the song had the word "day" in the title.
She dreamed of being a professional dancer, but injuries she suffered in a car accident made that impossible. She turned to singing and had a flourishing career as a big band singer before she got into motion pictures.
