Alexander Bogdanov originally cofounded the Bolshevik Party with Vladimir Lenin, but he was kicked out of the group by 1909 (before the revolution).
He shifted gears to science, medicine, and psychiatry, even inventing his own discipline, "tektology," an attempt to unify all the sciences.
In the 1920s, Bogdanov began experimenting with blood transfusions to "achieve eternal youth or at least partial rejuvenation." He even persuaded Stalin to create the Institute of Blood Transfusion.
Following 11 blood transfusions, Bogdanov said his eyesight improved and that his balding was "suspended." But he died when he took the blood of a student who had malaria and tuberculosis.
The student made a complete recovery.
