Alexander Bogdanov was a Russian physician and philosopher. He was a polymath who pioneered blood transfusion and general systems theory and made important contributions to cybernetics. He invented an original philosophy called “tectology”, now regarded as a forerunner of systems theory. He was also an economist, culture theorist, science fiction writer, and political activist.
“Immortality Day” was first published in 1912 under the title “Immortal Fride: A. Bogdanov’s Fantastic Narrative”.
