Charles Edward Coughlin ( KOG-lin; October 25, 1891 – October 27, 1979), commonly known as Father Coughlin, was a Canadian-American Catholic priest based near Detroit. He was the founding priest of the National Shrine of the Little Flower. Dubbed "The Radio Priest " and considered a leading demagogue, he was one of the first political leaders to use radio to reach a mass audience. During the 1930s, when the U.S. population was about 120 million, an estimated 30 million listeners tuned in to his weekly broadcasts. Coughlin was born in Ontario to working-class Irish Catholic parents.
