Richardson wrote Dark of the Moon with his cousin and frequent collaborator, William Berney.
With Richard Hart and Carol Stone heading the cast, Dark of the Moon opened on Broadway March 14, 1945 and ran for 318 performances.
In addition to two off-Broadway revivals, it became a perennial play with numerous college and high school productions in the decades that followed.
[2] Richardson's other plays include Design for a Stained Glass Window, about religious persecution, and Protective Custody, which had a short-lived 1956 New York production starring Faye Emerson.
In 1960, Richardson completed his doctorate at the University of Iowa and returned to Manhattan, where he lived at 207 Columbus Avenue.
