Although deemed a one-trick pony by some critics, Helen Morgan enjoyed a long career as a dancer, singer and actor, performing on stage, on radio and in Hollywood. In his new biography, Christopher S. Connelly finds Morgan everywhere he looks in American popular culture from the 1920s through her death in 1941. She often presented herself as a torch singer but offstage, he writes, “she was a delight, giggling through life with a sly glance and an outrageous pun.”
