Demikhov's two-headed dog. Vladimir Petrovich Demikhov (left, 1916-1998) was a Soviet surgeon who was famous for his pioneering transplant surgery. His most famous experiments were his head transplants on dogs, resulting in two-headed dogs such as the one seen here. His first dog head transplants were performed in 1954. In each case, the transplanted head was eventually rejected by the recipient dog's immune system, and died around 2 to 6 days after the operation. Photographed in Russia, in November 1967. For a picture of a set of dogs before transplantation, see image G352/402.
