Fred Francis Bosworth was an American evangelist, an early religious broadcaster, and a 1920s and Depression-era Pentecostal faith healer who was later a bridge to the mid-20th century healing revival. He was born on a farm near Utica, Nebraska and was raised in a Methodist home. His Methodist experiences also included salvation at the age of 16 or 17, and a spontaneous healing from major lung problems a couple of years later. Bosworth's life after that was one that followed Christian principles, though his church affiliation changed several times over the years. Several years after his healing he attended Alexander Dowie's church in Zion City, Illinois, then joined the Pentecostal movement and attended Pentecostal services. Most of his later ministry was associated with the Christian and Missionary Alliance church.

Faith healing is the practice of prayer and gestures that are believed by some to elicit divine intervention in spiritual and physical healing, especially the Christian practice. Believers assert that the healing of disease and disability can be brought about by religious faith through prayer or other rituals that, according to adherents, can stimulate a divine presence and power. Religious belief in divine intervention does not depend on empirical evidence of an evidence-based outcome achieved via faith healing. Virtually all scientists and philosophers dismiss faith healing as pseudoscience.
