Fyodorov was born in Russian city of Orenburg into a family of engineers.

Saint Petersburg ( tr: Sankt-Peterburg,) is a city and a federal subject of Russia located on the Neva River
From the age of fifteen he was deeply interested in the theory of polytopes which later became his main research interest. In Geometry, polytope is a generic term that can refer to a two-dimensional Polygon, a three-dimensional Polyhedron, or any of the various generalizations
He was a distinguished graduate of Gorny Institute, which he joined at the age of 26. Gorny Institute (Горный Институт also spelled Gornyi Institut is a Stratovolcano located in the Sredinny Range on the Kamchatka Peninsula
In 1895, he became a professor of geology in Moscow Agricultural Institute (now Timiryazev Academy). Year 1895 ( MDCCCXCV) was a Common year starting on Tuesday (link will display full calendar of the Gregorian calendar (or a Common year

In Geometry, polytope is a generic term that can refer to a two-dimensional Polygon, a three-dimensional Polyhedron, or any of the various generalizations Space is the extent within which Matter is physically extended and objects and Events have positions relative to one another
- He wrote the classic "Symmetry of the polytope systems" (approximate translation from Russian) which contained the first cataloging of the 230 space groups. Russian ( transliteration:,) is the most geographically widespread language of Eurasia, the most widely spoken of the Slavic languages The space group of a Crystal or crystallographic group is a mathematical description of the Symmetry inherent in the structure
