F. F. (Fred Francis) Bosworth (1877-1958) strongly influenced many of the early healing evangelists, including Oral Roberts, T. L. Osborn, John G. Lake, and many others. Bosworth worked with John Alexander Dowie for a number of years before starting his own healing ministry. He embraced Pentecostalism as a result of being influenced by Charles Parham in 1906. He was also influenced by E. W. Kenyon and his teachings on divine healing. Bosworth's reputation spread rapidly throughout the 1920s as a result of a number of healing campaigns that he held throughout North America and Canada. He established The National Radio Revival Missionary Crusaders and began broadcasting in Chicago, with a tremendous response from the listeners. First published in 1924, his book Christ the Healer is a tremendous work on the principles of healing through the finished work of Christ on the cross at Calvary. Bosworth died in 1958, having been one of the pioneers of faith and divine healing.
