Fyodorov was born in 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 Gorny Institute, which he joined at the age of 26.

[edit] Books

His first book, "Basics of Polytopes", was finished in 1879 and published in 1885. It offers a classifification of polytopes and derives Fyodorov polytopes, congruent polytopes that can completely fill space.
He wrote the classic "Symmetry of the polytope systems" (approximate translation from Russian) which contained the first cataloging of the 230 space groups.
