Page "Konstantin Tsiolkovsky" Paragraph 5

Tsiolkovsky worked as a high school mathematics teacher until retiring in 1920.

He did not particularly flourish under a communist system, in particular Tsiolkovsky's support of eugenics made him politically unpopular.

However, from the mid 1920s onwards the importance of his other work was acknowledged, and he was honoured for it.

He died on 19 September 1935 in Kaluga and was buried in state.
