Alexander played so many roles on radio it would be a Herculean task to name every program she was on but a few of the notable series include Bright Horizon, This is Your FBI, Studio One, Crime Club, The Falcon, The Big Story, Mr. President, The Shadow, Barry Craig, Confidential Investigator and X Minus One. Her most permanent radio gigs outside of Superman were as loyal secretary
Della Street on Perry Mason, and dependable gal Friday Ellen Deering on Philo Vance.
The only television venue that I remember Alexander actively participating in was the panel show The Name’s the Same (1952-55), a series that also featured some OTR vets in Robert Q. Lewis, Meredith Willson, Clifton Fadiman, Abe Burrows and Bill Stern. Same was at one time prominently featured on The Game Show Network’s black-and-white lineup but it looks as if that novelty has come to pass.
R.I.P, Joan. You will be missed.
