By 1922, Urysohn had given topological definitions to curve, surface, and dimension, and his work attracted the attention of many prominent
European mathematicians. In the summers of 1923 and 1924, Urysohn and his friend and fellow mathematician,

At that time, Urysohn’s interests lay predominantly in physics. Urysohn enrolled at the Moscow State
University in 1915 and earned his Bachelor of science in 1915. There he attended the lectures of
