The series was created by Irna Phillips, who based it on personal experiences. After giving birth to a still-born
baby at age 19, she found spiritual comfort listening to the radio sermons of Preston Bradley, a famous Chicago preacher and founder of the
People's Church, a church which promoted the brotherhood of man. These sermons originated the idea of the creation of The Guiding Light,
which began as a radio series. The original radio series was first broadcast as 15-minute episodes on NBC Radio, starting on January 25,
1937. The series was transferred to CBS Radio during 1947.
