Friedrich Tsander

Friedrich Tsander was born in Riga, Livonia, Russian Empire, in 1887. Tsander and others founded the Society for Studies of Interplanetary Travel in 1924. One of its objectives was promoting the work of Konstantin Tsiolkovsky, whose theoretical work about the rocket as the way to get into space went back decades. Tsander published articles on theories about human spaceflight and helped design the first successful Soviet liquid-fuel rocket.
