Vaughn De Leath was an American female singer who gained popularity in the 1920s, earning the sobriquets "The Original Radio Girl" and the "First Lady of Radio." Although very popular in the 1920s, De Leath is obscure in modern times.

A crooner is a singer that performs with a smooth, intimate style that originated in the 1920s. The style was made possible by better microphones which picked up quieter sounds and a wider range of frequencies, allowing the singer to access a more dynamic range. This suggestion of intimacy was supposedly wildly attractive to women, especially younger ones such as teenage girls, known at the time as "bobby soxers". The crooning style developed out of singers who performed with big bands, and reached its height in the 1940s to late 1960s.
