CELEBRITY OF THE MONTH
Konstantin Eduardovich Tsiolkovsky
160th Birthday (17 September 1857 – 19 September 1935)
Pioneer of astronautic theory
Konstantin Eduardovich Tsiolkovsky was born on September 17, 1857, in Izhevskoye,
Spassk District, Russia. He was the son of a Polish deportee to Siberia. He became a
"people's school teacher" at Borovsk, Kulaga Province, in 1878. He formulated the
mathematical fundamentals of modern astronautics. He showed that space travel was
possible only by means of rocket propulsion. He began to devote more attention to space
problems. In 1895 his book Gryozy o zemle i nebe (Dreams of Earth and Sky) was
published, and in 1896 he published an article on communication with inhabitants of
other planets. In the same year he also began to write his largest and most serious work
on astronautics, “Exploration of Cosmic Space by Means of Reaction Devices,” which
dealt with theoretical problems of using rocket engines in space, including heat transfer,
a navigating mechanism, heating resulting from air friction, and maintenance of fuel
supply.
