Max Gerson (October 18, 1881 – March 8, 1959) was a German-born American physician who developed the Gerson Therapy, a dietary-based alternative cancer treatment that he claimed could cure cancer and most chronic, degenerative diseases.
Gerson described his approach in the book A Cancer Therapy: Results of 50 Cases. The National Cancer Institute evaluated Gerson's claims and concluded that his data showed no benefit from his treatment. The therapy is both ineffective and dangerous.
Gerson was born in Wongrowitz, German Empire (Wągrowiec, now in Poland), on October 18, 1881. In 1909, he graduated from the Albert-Ludwigs-Universität Freiburg. He began practicing medicine at age 28 in Breslau (Wrocław, now in Poland), later specializing in internal medicine and nerve diseases in Bielefeld. By 1927, he was specializing in the treatment of tuberculosis, developing the Gerson-Sauerbruch-Hermannsdorfer diet, claiming it was a major advance in the treatment of tuberculosis. Initially, he used his therapy as a supposed treatment for migraine headaches and tuberculosis. In 1928, he began to use it as a claimed treatment for cancer. He left Germany in 1933 and emigrated first to Vienna, where he worked in the West End Sanatorium. Gerson spent two years in Vienna, then in 1935 he went to France, associating with a clinic near Paris before moving to London in 1936. Shortly after that, he moved to the United States where he settled in New York City.
Gerson emigrated to the United States in 1936, passed his medical board examination, and became a U.S. citizen in 1942.
In the U.S., Gerson applied his dietary therapy to several cancer patients, claiming good results, but other workers found his methodology and claims unconvincing. Proponents of the Gerson Therapy believe a conspiracy headed by the medical establishment prevented Gerson from publishing proof that his therapy worked. In 1958, Gerson published a book in which he claimed to have cured 50 terminal cancer patients: A Cancer Therapy: Results of 50 Cases. In 1953, Gerson's malpractice insurance was discontinued and, in 1958, his medical license in New York was suspended for two years. Gerson died March 8, 1959 of pneumonia.
