Earl Nightingale (March 12, 1921 – March 28, 1989) was an American radio personality, writer, speaker, and author, dealing mostly on the subjects of human character development, motivation, excellence and meaningful existence; so named as the "Dean of Personal Development." He was the voice in the early 1950s of Sky King, the hero of a radio adventure series, and was a WGN radio show host from 1950 to 1956. Nightingale was the author of The Strangest Secret, which economist Terry Savage has called “…one of the great motivational books of all time“.
