Historian Frank L. Anderson tells the story of Theophilus Riesinger, a Capuchin friar from Appleton, Wisconsin who became America’s foremost exorcist. Riesinger performed at least 22 exorcisms in his lifetime, but it was the harrowing case of demonic possession in 1928 that became the most publicized case of exorcism in American history.
The details, based on eyewitness accounts, were published in the early 1930s in a 48-page booklet called Begone Satan! by Rev. Carl Vogl. It was originally written in German, but when it was translated into English in 1935, the case garnered widespread attention in Catholic publications, newspapers, and even Time magazine.
