Origins & Early Life

Pafnuty Lvovich Chebyshev (Russian: Пафну́тий Льво́вич Чебышёв, IPA: [pɐfˈnutʲɪj ˈlʲvovʲɪtɕ tɕɪbɨˈʂof]) (16 May [O.S. 4 May] 1821 – 8 December [O.S. 26 November] 1894) was a Russian mathematician and considered to be the founding father of Russian mathematics. Chebyshev is known for his fundamental contributions to the fields of probability, statistics, mechanics, and number theory.

Pivotal Works & Achievements

A number of important mathematical concepts are named after him, including the Chebyshev inequality (which can be used to prove the weak law of large numbers), the Bertrand–Chebyshev theorem, Chebyshev polynomials, Chebyshev linkage, and Chebyshev bias. The surname Chebyshev has been transliterated in several different ways, including Tchebichef, Tchebychev, Tchebycheff, Tschebyschev, Tschebyschef, Tschebyscheff, Čebyčev, Čebyšev, Chebysheff, Chebychov and Chebyshov (which provides the closest pronunciation in English to the correct pronunciation in old Russian). Chebychev is an erroneous mixture between English and French transliterations. In English, the transliteration Chebyshev has gained widespread acceptance. The correct transliteration according to ISO 9 is Čebyšëv.
