Evangelist Aimee Semple McPherson was one of the most famous people in the US in the 1920s and 1930s.
Known as "Sister Aimee", she pioneered the use of mass broadcast technologies such as radio to send her Pentecostal message to people around the country, and she drew tens of thousands of people to her faith healing events.
So when she disappeared on May 18, 1926, it caused a huge commotion.
McPherson vanished from Ocean Park Beach in Santa Monica, California, prompting fears she had drowned. However, a search was unable to find any sign of her.
On June 23, her church, Angelus Temple, held a memorial service for her - only for her mother Mildred Kennedy to receive a phone call from officials in Arizona to tell her that McPherson was alive and in hospital.
