#1 Alexander Aleksandrovich Bogdanov (22 August 1873 [O.S. 10 August] – 7 April 1928)
Alexander Aleksandrovich Bogdanov was a Russian and Soviet physician, philosopher, science fiction writer, and revolutionary of Belarusian ethnicity.
In 1924, Bogdanov started his blood transfusion experiments, apparently hoping to achieve eternal youth or at least partial rejuvenation. Lenin’s sister Maria Ulyanova was among many who volunteered to take part in Bogdanov’s experiments. After undergoing 11 blood transfusions, he remarked with satisfaction on the improvement of his eyesight, suspension of balding, and other positive symptoms. The fellow revolutionary Leonid Krasin wrote to his wife that “Bogdanov seems to have become 7, no, 10 years younger after the operation”. In 1925–1926, Bogdanov founded the Institute for Haemotology and Blood Transfusions, which was later named after him. But a later transfusion cost him life, when he took the blood of a student suffering from malaria and tuberculosis. (Bogdanov died, but the student injected with his blood made a complete recovery.) Some scholars (e.g. Loren Graham) have speculated that his death may have been a suicide, because Bogdanov wrote a highly nervous political letter shortly beforehand. Others, however, attribute his death to blood type incompatibility, which was poorly understood at the time.
