Editing Pafnuty Chebyshev (section)

=== Early years ===
One of nine children,<ref Name=MacTutor>[http://www-history.mcs.st-andrews.ac.uk/Biographies/Chebyshev.html Biography in MacTutor Archive]</ref> Chebyshev was born in the village of Okatovo in the district of [[Borovsk]], [[province of Kaluga]]. His father, Lev Pavlovich, was a Russian nobleman and wealthy landowner. Pafnuty Lvovich was first educated at home by his mother Agrafena Ivanovna Pozniakova (in reading and writing) and by his cousin Avdotya Kvintillianovna Sukhareva (in [[French language|French]] and [[arithmetic]]). Chebyshev mentioned that his music teacher also played an important role in his education, for she "raised his mind to exactness and analysis".{{citation needed|date= October 2022}}

[[Trendelenburg gait|Trendelenburg's gait]] affected Chebyshev's adolescence and development. From childhood, he limped and walked with a stick and so his parents abandoned the idea of his becoming an officer in the family tradition. His disability prevented his playing many children's games and he devoted himself instead to mathematics.{{citation needed|date= October 2022}}

In 1832, the family moved to [[Moscow]], mainly to attend to the education of their eldest sons (Pafnuty and Pavel, who would become lawyers). Education continued at home and his parents engaged teachers of excellent reputation, including (for mathematics and physics) the senior [[Moscow University]] teacher {{ill|Platon Pogorelsky|ru|Погорельский, Платон Николаевич}}, who had taught, among others, the future writer [[Ivan Turgenev]].{{citation needed |date= October 2022}}
