Yevgraf Fyodorov

Yevgraf Stepanovich Fyodorov, sometimes spelled Evgraf Stepanovich Fedorov (Russian: Евгра́ф Степа́нович Фёдоров) (December 22, 1853–May 21, 1919), was a Russian mathematician, crystallographer, and mineralogist.

Fyodorov was born in the Russian city of Orenburg into a family of engineers. The family later moved to Saint Petersburg.

From the age of fifteen he was deeply interested in the theory of polytopes, which later became his main research interest.

He was a distinguished graduate of the Gorny Institute, which he joined at the age of 26.

He contributed to the identification of conditions under which a group of Euclidean motions must have a translational subgroup whose vectors span the Euclidean space.

In 1895, he became a professor of geology at the Moscow Agricultural Institute (now the Timiryazev Academy).

Fyodorov died from starvation in 1919 during the Russian Civil War in Petrograd, RSFSR.
