Zé Arigó, the 'surgeon with a rusty knife'
From about 1950 José Pedro de Freitas, known as Zé Arigó, treated thousands of people a day in Congonhas, Minas Gerais. He said a dead German doctor, 'Dr. Fritz', operated through him, sometimes with a kitchen knife and no anaesthetic.

The account
He was convicted of illegal practice of medicine in 1958 and again in 1964. The American researcher Andrija Puharich filmed him in 1963 and had a lipoma removed from his own arm. Arigó died in a car crash in 1971. Other mediums, among them Edson Queiroz in Recife, later claimed to channel 'Dr. Fritz'.
The sceptical view
There are no controlled follow-up studies of his patients. Some of his 'operations' were minor surface procedures, and the prescriptions he wrote were often for ordinary drugs.
The researched reading
A charismatic healer with a "spirit doctor" and rapid minor surgeries. Skill, suggestion and belief explain most of his fame; no controlled study shows anything more.
| Explanation | Weight | Why |
|---|---|---|
| Perception, memory or mind | 35% | Patients’ belief, shock and suggestion can reduce pain and produce reported improvement; many "cures" were never followed up. |
| A cultural story | 25% | Brazilian Spiritism, with its tradition of healing mediums and spirit doctors, framed Arigó’s work and drew believers. |
| A hoax or fabrication | 15% | Many operations were minor surface procedures that a skilled lay practitioner can do quickly; his prescriptions were often ordinary drugs. He was convicted of illegal practice of medicine twice. |
| Undetermined | 10% | The share the reading had given to fabrication on doubt rather than evidence: the record does not settle it either way. |
| Genuinely anomalous | 8% | Puharich filmed rapid operations without anaesthesia or infection, but there are no controlled studies of outcomes. |
| A known natural phenomenon | 5% | Lipoma removal and similar procedures heal normally; nothing unusual is required. |
| Something in the surroundings | 2% | Surroundings play no clear part in claimed psychic surgery. |
Official position: Brazilian courts convicted him of illegal practice of medicine; no medical body validated his results.
