In the 1950s, psychic surgeon Zé Arigó (1918–1971) claimed to be operating as a channel for the spirit of a Dr. Adolf Fritz, a German doctor who had died in World War I. Arigó became famous in Brazil and abroad, and was the subject of documentaries and books.
After Arigó's death in a car accident, two brothers, Oscar and Edivaldo Wilde, claimed to channel the spirit of Dr. Fritz.
Their careers were cut short when both died in violent car crashes.
Queiroz treated hundreds of thousands of patients in the guise of Dr. Fritz, while further advancing the techniques of Arigó.
Exhaustive research has found no mention of a doctor with any of those names in German records.
