Aimee Semple McPherson, commonly known as "Sister Aimee," was a Canadian-American Christian evangelist and founder of the Foursquare Church. She was born Aimee Elizabeth Kennedy on October 9, 1890, and died September 27, 1944. She was commonly called "Sister Aimee."
McPherson was a pioneer in the use of modern media, especially radio, and was the second woman to be granted a broadcast license. She used radio to draw on the growing appeal of popular entertainment in North America and incorporated other forms into her weekly sermons at Angelus Temple. McPherson's public faith-healing demonstrations before large crowds allegedly healed tens of thousands of people.
