Altaisky and Tsiolkovsky. The writer K. Altaisky (left) with the Russian rocket pioneer Konstantin Eduardovich Tsiolkovsky (1857-1935). Between then is a model of one of Tsiolkovsky's rocket designs. Although he never built a working rocket, Tsiolkovsky's work was highly influential in the development of Soviet rocket and space technology. He became deaf after contracting scarlet fever at around the age of 10 and from then on he schooled himself, mainly from books in his father's library. He determined that the Earth's escape velocity was 8 kilometres per second and showed that this could be achieved using liquid-fuel rockets. Photographed in 1927, in Kaluga, Russia.
