Of course, Joan Alexander would be more than the voice of Lois Lane on radio and in theatrical animated shorts. She was the original voice of Della Street on the radio show Perry Mason; she would be followed by Jan Miner and Gertrude Warner in the role. She also played detective Philo Vance's secretary Ellen Deering on the 1948-1950 radio show Philo Vance, and appeared on soap operas such as Against the Storm, Light of the World, Lone Journey, and This is Nora Drake. She also guest starred on the science fiction radio show Dimension X.
In tribute to Miss Alexander on the occasion of the 100th anniversary of her birth, here she is playing her most famous role in the very first Fleischer Studios Superman cartoon, the Oscar nominated "Superman" (also known as "The Mad Scientist").
