Question: Where was the father of Evgraf Fedorov Jr. born?

Knowledge 1: Evgraf Fedorov Jr.
Yevgraf Yevgrafovich Fyodorov (in Saint Petersburg – 19 July 1965 in Moscow), was a Russian climatologist.He was a son of Russian mathematician Yevgraf Fyodorov.Graduation from the University of Saint Petersburg 1910.Researcher in the Magneto-Meteorological Observatory, Pavlovsk 1911-1934, professor of geography with the USSR Academy of Sciences 1934-1951.Corresponding Member of the USSR Academy of Sciences from 1946.Fyodorov's main contribution consisted in detailed development in descriptive climatology, with a method to describe local climates in terms of daily weather observations. [SEP] Knowledge 2: Evgraf Fedorov
Evgraf Stepanovich Fedorov (– 21 May 1919) was a Russian mathematician, crystallographer and mineralogist.Fedorov was born in the Russian city of Orenburg.His father was a topographical engineer.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.His best-known result is his 1891 derivation of the 230 symmetry space groups which now serve as the mathematical basis of structural analysis.He also proved that there are only 17 possible wallpaper groups which can tile a Euclidean plane.This was then proved independently by George Pólya in 1924.The proof that the list of wallpaper groups was complete only came after the much harder case of space groups had been settled.In 1895, he became a professor of geology at the Moscow Agricultural Institute (now the Timiryazev Academy).Fedorov died from pneumonia in 1919 during the Russian Civil War in Petrograd, RSFSR.He developed the Federov stage for polarizing microscopes, a tool for crystallography which allows a mineral specimen to be studied under precise angles of tilt and rotation, providing an analysis of crystal structure.
