The Nemyzki family moved to Moscow in 1904. In 1921 Nemyzki began his studies at the physical-mathematical faculty of the Moscow University of Technology , with which he remained lifelong. From 1925 to 1929 he was a research student under Alexandrow and Stepanow and concluded with a thesis on the axioms of metric space . Subsequently, Nemyzki did his doctorate with a thesis on non-linear integral equations.

Nemyzki's main areas of work were topology , non-linear functional analysis (especially non-linear integral equations ) and the qualitative theory of ordinary differential equations . The Niemytzki space and the Nemytskii operator are named after him.

Nemyzki was married to the mathematician Nina Bari . He died on August 7, 1967 while hiking in the Sayan Mountains .
