A writer and producer who turned radio drama into a serious art form during its 1930s and 40s golden age, using popular entertainment to take on social issues at a time when the medium mostly avoided them. Peers included Orson Welles, and his influence on later writers ran from Rod Serling and Gene Roddenberry to Norman Lear; he later headed special media programming for the United Nations and taught journalism at USC until age 97.
