[編集] 生涯

Lyapunov was born in Yaroslavl, Imperial Russia. His father Mikhail Vasilyevich Lyapunov (1820-1868) was a well known astronomer and a head of the Demidovski lyceum. Because of the reaction of the university administration, after the departure of Lobachevsky, he gave up his work entirely in 1864 at the observatory of the University of Kazan. He moved with his family on his wife's estate in Simbirsk province (now Ulyanovsk Oblast), where he devoted his time to the education of his oldest sons, Aleksandr and Sergei (1859-1924). During long winter nights he stayed with his sons and he taught them assiduously with the aid of games on maps of the world. He possessed a lot of books in Russian, German and French on subjects as varied as mathematics, astronomy, philosophy, history, ethnography, political economy and literature. After the sudden death of his father Aleksandr was educated by his uncle R. M. Sechenov, brother of the famous physiologist Ivan Mikhailovich Sechenov. At his uncle's Lyapunov learned with his cousin, his intended Nataliya Rafailovna. In 1870 his mother moved with her sons to Nizhny Novgorod, where he started to attend the third class of the gymnasium. He passed gymnasium in 1876 with distinction

1918年10月31日に妻を亡くし、同日ピストル自殺を図って3日後に死亡した。
