One of the famous and crazy scientists, yes he is Vladimir Petrovich Demikhov a Soviet scientist. And he's doing weird experiments with dog heads, keeping them alive apart from their bodies and transplanting into other dogs' bodies. Born in 1916, Demikhov became famous for experiments in organ transplants during the 30s and 50s, having run as a surgeon at the Red Army hospital during World War II. During the days of battle, sewing wounds and amputations, he has a very crazy idea: Could it be for human heart and lung human transplants?
