Barney Rapp was the orchestra leader of Barney Rapp and His New Englanders in Cincinnati. It was on these local radio stations that Doris Day got her start in the entertainment business. Rapp eventually hired her to be a part of his ensemble after a talent scout recommended her, despite the fact that she was only a teenager (via American Israelite). Antique Trader explains that Rapp was the one who suggested that Day change her name. He felt her last name, Kappelhoff, was and unappealing. Rapp convinced her to change her name to Day after one of the songs in her playlist, “Day by Day.”
There was more to Rapp’s issue with the name Kappelhoff. He wanted to start advertising her performances, but Kappelhoff was too long for the marque. Day herself did not agree with the name change, but she always credited it and her subsequent opportunities to perform with other artists like Les Brown (via American Israelite). Though she is well-known for her film roles, Doris Day Magic states her career took off from this time as a vocalist. If it weren’t for her beginnings in music, perhaps she may have not been influenced to make the switch to that household name that became recognizable.
