Re radio script writing, Ruth Woodman wrote
Death Valley Days for both radio and television. She created the series in 1930 for radio, writing over 700 scripts during its run until 1945. When the show transitioned to television in 1952, Woodman continued writing all scripts for the first five years and later served as story editor until her retirement in 1970.
AND, she had never set foot in the west when she started writing. But she was a stickler for authenticity and traveled all over the west getting story ideas and interviewing people.
