#7 Alexander Bogdanov

Alexander Bogdanov was a noted Russian physician who is better known as a pioneer in blood transfusion. He started the first blood bank in Moscow. His scientific experiments in blood transfusion revolve around the idea of attaining eternal youth. He believed that receiving blood from healthy people is the key to rejuvenation and he had successfully experimented the transfusion with many noted people including Lenin’s sister.

Bogdanov also conducted 11 successful blood transfusions in his own body. His colleague even wrote a letter to his wife "Bogdanov seems to have become 7, no, 10 years younger after the operation".

Everything was going fine till Bogdanov made his 12^th blood transfusion. One day injected himself with the blood of a student who was suffering from malaria and tuberculosis. It proved fatal and he died of the infections shortly after. But the student, injected with Bogdanov’s blood made a complete recovery.
