Invention: Blood transfusions Country: Russia (then Soviet Union) Died: 1928 More than just an inventor, Alexander Bodganov was also a well-known philosopher, writer, economist and physician, as well as a prominent political figure during the rise of the Soviet Union. However, his greatest passion was in uncovering the mysteries behind blood transfusions. Bogdanov believed that through blood transfusions, human rejuvenation could be possible. Unfortunately though, his attempts at reversing the aging process eventually led him to an early grave. Over the course of four years, Bogdanov underwent 11 blood transfusions himself, remarking that it had improved his eyesight and generally made him feel much younger. Unfortunately, he later underwent a transfusion with a student with malaria and tuberculosis, leading to his untimely death in 1928.
