Ryke Geerd Hamer

Hamer lived in voluntary exile in Spain until March 2007, when Spanish medical authorities held him responsible for dozens of preventable deaths. By 1997, Hamer owned clinics in Germany, Belgium, Italy, Austria, and the Netherlands, and resided in Norway until his death from a stroke on 2 July 2017, age 82.

After negotiations, including the intervention of the Austrian President Thomas Klestil, the parents were persuaded to return to Austria. By then, Pilhar's health had deteriorated. The tumor had grown very large, weighing four kilograms, filling most of her abdominal cavity and was pressing against her lungs. The lack of treatment had reduced the estimate of survival probability from 90% to 10%. After a court ordered conventional cancer treatment with surgery, chemotherapy and radiation therapy, Pilhar recovered completely and was still alive in 2010. Her parents received an eight-month suspended jail sentence in Austria.

Hamer purported that his method is a "Germanic" alternative to mainstream clinical medicine, which he claimed is part of a Jewish conspiracy to decimate non-Jews. In this, Hamer repeated the antisemitic claims of Nazi physician Gerhard Wagner. More precisely, Hamer asserted that chemotherapy and morphine are used to "mass murder" Western civilisation, while such treatment is not used in Israel. Hamer promoted the idea that most German oncologists are Jewish and that "no Jew is treated with chemotherapy in Germany." According to him, hypodermic needles are used during chemotherapy to implant "chips" containing "chambers of poison" that can be activated by satellite to specifically kill patients. He proposed that the swine flu vaccination campaign of 2009 was also used to mark people with those "chips" and denied the existence of HIV. Hamer also believed that the denial of recognition of his theories and the revocation of his practitioner's licence is due to a Jewish conspiracy.

In 2008, Hamer presented a document where one "Chief Rabbi" "Esra" Iwan Götz confirmed the existence of a conspiracy among Jewish oncologists to use the "torture" of chemotherapy on all non-Jewish patients, while Jewish patients were to receive the "correct" treatment of GNM. Götz, a German holocaust denier active in the German Reich revivalism scene, has been repeatedly convicted by German courts for fraud, defamation, misuse of academic titles (the title "Chief Rabbi" is not legally protected in Germany), and the falsification of documents, among others.

In 1995, Hamer was associated with the case of Olivia Pilhar, a six-year-old Austrian girl who suffered from a Wilms' tumor. Pilhar's parents were members of Fiat Lux, a new religious movement whose leader Uriella referred them to Hamer. He diagnosed the girl as having several "conflicts" rather than cancer. When the parents refused conventional medical therapy for Pilhar, the Austrian government removed their rights of care and control. The parents fled with their daughter to Spain, which was Hamer's place of residence at the time.

Hamer's license to practice medicine was revoked in 1986 by a court judgment, which was reconfirmed in 2003. As he continued to practice, Hamer was investigated several times over allegations of malpractice and causing the deaths of patients. He was jailed for twelve months in Germany from 1997 to 1998, and served a prison term from September 2004 to February 2006 in Fleury-Mérogis, France, on counts of fraud and unlicensed practice of medicine.

On 8 August 1978, Hamer's son, Dirk, was shot by the son of the last king of Italy, Vittorio Emanuele of Savoy, while asleep on a yacht off Cavallo and died on 7 December of that year. Sometime after Dirk's death, Hamer developed testicular cancer and thought there was a link between the two events, so he began to develop Germanic New Medicine (GNM), which can be summarized in its "five biological laws":

Hamer held a licence to practice medicine from 1963 until 1986, when it was revoked for malpractice. His system came to public attention in 1995, when the parents of a child suffering from cancer refused medical treatment (chemical therapy or chemotherapy) in favour of Hamer's methods. Hamer was charged with malpractice and imprisoned in several European countries.

Ryke Geerd Hamer (17 May 1935 – 2 July 2017) was a German ex-physician and the originator of Germanic New Medicine (GNM), also formerly known as German New Medicine and New Medicine, a system of pseudo-medicine that purports to be able to cure cancer. The Swiss Cancer League described Hamer's approach as "dangerous, especially as it lulls the patients into a false sense of security, so that they are deprived of other effective treatments."

Ryke Geerd Hamer was born in Mettmann, North Rhine-Westphalia, Germany, in 1935. He received his high school diploma at age 18 and started medical and theological studies in Tübingen, where he met Sigrid Oldenburg, a medical student who later became his wife. At age 20, Hamer passed the preliminary examination in medicine, and in April 1962 passed his medical state examination in Marburg, Hesse. He was granted a professional license as a doctor of medicine in 1963. After spending several years at the University Clinics of Tübingen and Heidelberg, Hamer completed his specialization in internal medicine in 1972. He also worked in several practices with his wife and patented several inventions.
