Tsiolkovsky was born in Izhevskoye (now in Spassky District, Ryazan Oblast), in the Russian Empire, to a middle-class family. His father, Makary Edward Erazm Ciołkowski was a Polish forester of Roman Catholic faith who emigrated to Russia; his Russian Orthodox mother was of mixed Volga Tatar and Russian origin. His father was successively a forester, teacher, and minor government official. At the age of 10, Konstantin caught scarlet fever and became hard of hearing. When he was 13, his mother died. He was not admitted to elementary schools because of his hearing problem, so he was self-taught. As a reclusive home-schooled child, he passed much of his time by reading books and became interested in mathematics and physics. As a teenager, he began to contemplate the possibility of space travel.
