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