Meet Vladimir Demikhov: Scientist who created a two-headed dog and changed medicine forever

In the 1950s, Soviet surgeon Vladimir Demikhov conducted controversial experiments, including creating two-headed dogs by surgically grafting heads onto other dogs. These procedures, though ethically troubling, aimed to understand organ transplantation and circulation. Demikhov's work laid crucial groundwork for modern transplant medicine, influencing pioneers like Christiaan Barnard.
