Dr. Donald Ewen Cameron was an infamous pioneer in "re-patterning" (or brainwashing) techniques, and his research has been used in the development of modern torture.
Donald Ewen Cameron (1901—1967) was born in Scotland in 1901 and graduated from the University of Glasgow in 1924. He began his career as resident surgeon at Glasgow Infirmary, but in 1929 moved to Canada to work in the Brandon Mental Hospital. In 1943 he founded McGill University's psychiatry department while working with the U.S. Office of Strategic Services. In 1945 Cameron was sent to Germany to determine whether Rudolf Hess was fit to stand trial at Nuremberg. After the war he developed his "re-patterning" techniques at Albany State Medical School. In 1957 Cameron was put in charge of the CIA's "mind-control" project, MK-ULTRA, at the Allan Memorial Institute in Montreal. He died in 1967.
