Evgraf Stepanovich Fedorov (Евграф Степанович Фёдоров) (December 22, 1853-May 21, 1919), was great Russian mathematician, crystallographist, mineralogist.
Evgraf Fedorov was born in Russian city of Orenburg in the family of engineer. Later family moved to Saint Petersburg.
From the age of 15 he was deeply interested in the theory of polytopes that determined his main research interests.
He was distinguished graduated of Gorny Institute, which he joined at the age of 26.
In 1895 he became professor of geology in Moscow Agricultural Institute (now Timiriazev Academy).
Books
- His first book "Basics of Polytopes" was finished in 1879 and published in 1885. There he classifies polytopes, derived his famous Fedorov Polytopes (polytopes that all equal and can completely fill the space).
- He wrote classical book "Symmetry of the polytope systems" (approximate translation from Russian) which contained the first derivation of 230 groups of spatial symmetry.
