In this episode of pplpod, we explore the life of Aimee Semple McPherson, the Canadian-born evangelist who built the template for the modern megachurch, pioneered religious broadcasting, and became one of the most famous and polarizing women in America. Born in Ontario in 1890 and raised around her mother's Salvation Army work, she learned early that faith could be public, active, and theatrical. She married the Pentecostal missionary Robert Semple, who died in Hong Kong in 1910, leaving her a widow with a newborn. After a second marriage to Harold McPherson, depression, and a near-death surgery in 1914, she accepted what she believed was a call to preach and took to the road in her "gospel car."

The episode follows McPherson to Los Angeles, where she founded the Foursquare Gospel and opened the 5,000-seat Angelus Temple in 1923. She used stage sets, orchestras, and spectacles like her motorcycle-cop sermon to compete with Hollywood, drew massive crowds to healing services, and became the first woman to preach by radio, later launching station KFSG. During the Great Depression her commissary fed an estimated 1.5 million people, and she worked to integrate her services. In 1926 her disappearance at Ocean Park Beach and reappearance in Mexico set off a media frenzy and a failed prosecution for conspiracy and perjury, followed by family lawsuits, breakdowns, and a stylish new public image. In World War II she dropped the church's pacifism and sold war bonds. She died in 1944 at 53 of an accidental overdose, leaving a legacy of showmanship, populism, and an enduring denomination.
