It is difficult to answer this question because you did not tell us which decade (or even which country). Assuming you are referring to the United States, there have been many popular jazz singers: they include Louis Armstrong, Al Jolson, Belle Baker, Nat "King" Cole, Ethel Waters, and Billie Holiday. Some people would also say that Frank Sinatra sang some jazz songs, even though he is more identified with big band music and later, with middle-of-the-road vocal music.
From the movie of that name? Eddie Cantor.

There are many well known, world famous jazz singers, however one of the most famous is Louis Armstrong. Best known for his trumpet playing he was also a talented jazz singer. His voice delighted audiences, as did his often-humorous scat singing. Armstrong is considered the father of modern jazz.
She was an Amazing Jazz and Blues singer who is highly underrated!
