Mathematician:Pafnuty Lvovich Chebyshev

Pafnuty Lvovich Chebyshev (Russian: Пафну́тий Льво́вич Чебышёв) was a Russian mathematician.

His name can also be written as Chebychev, Chebyshov, Tchebycheff or Tschebyscheff. Some sources even use Čebyšev, but modern usage discourages the unnecessary use of diacritics.

His work was mainly in the fields of probability, statistics and number theory.

He is best known for proving Bertrand's Postulate in 1850. It has since been known as the Bertrand-Chebyshev Theorem.
