How Doris became Doris Day
Doris Kappelhoff was a teenage band singer when bandleader Barney Rapp suggested a new name in 1939. He thought her surname was too long to fit on a marquee.
The replacement came from her own act: Rapp admired the way she sang "Day After Day", so she became Doris Day. She kept her real first name.
