Alexander Bogdanov

Bogdanov, a Soviet physician, philosopher, activist, science fiction writer, and feminist, was certainly a unique thinker. He was a high-ranking officer during the Russian Revolution and invented tectology, the precursor to systems theory.  In 1924, Bogdanov founded theInstitute for Hematology and Blood Transfusion, stating  that he could achieve eternal youth by using human blood. 

Even Lenin's sister was on board, and Bogdanov ended up having no less than 11 transfusions himself. The last patient's blood was infected with malaria and tuberculosis, or perhaps was incompatible with Bogdanov's blood type, and Bogdanov died.Today, many scholars think that Bogdanov may have killed himself, because he had written a strange letter before his death, and also had a number of political enemies.
