Far behind the Iron Curtain of cold war Russia Vladimir Demikhov was a pioneer in what he coined “transplantology”. He dealt in the transplants of organs and limbs in various animals. In 1954 he created his most notorious work. He grafted the head and forelegs of a puppy to the neck of an adult dog. With their windpipe and blood vessel’s connected this dog lived for 6 days with the puppy head displaying the behavior of a puppy and the adult dog displaying the behavior of an adult.
Christiaan Barnard who performed the world first human heart transplant cited Demikhov as one of his mentors.
