The Two-Headed Dog Surgeon

On 1954, soviet surgeon Vladimir Demikhov, revealed his masterpiece to the world: a two-headed dog. The head of a puppy had been grafted onto the neck of an adult German shepherd.

 The second head would lap at milk, even though it did not need nourishment and though the milk then dribbled down the neck from its disconnected oesophagus.

 Although both animals soon died because of tissue rejection, that did not stop Demikhov from creating 19 more over the next 15 years.
