His father, Colonel Simion Stoilow, fought at the Battle of Smârdan [ro] in the Romanian War of Independence.

In July 1947 he organized at Club de Chaillot the exhibit "L'art français au secours des enfants roumains"; Constantin Brâncuși participated, Tristan Tzara and Jean Cassou wrote the preface to the catalogue.

Among his students at the University of Bucharest and at the Institute were Cabiria Andreian Cazacu, Romulus Cristescu, Martin Jurchescu, Ionel Bucur, and Aristide Deleanu,[2] as well as Nicolae Boboc, Corneliu Constantinescu, and Aurel Cornea.

Prior to the Romanian Revolution of 1989, his funeral urn was maintained in a crypt at the Carol Park Mausoleum.

The Institute of Mathematics of the Romanian Academy (closed in 1975 by a decree of Nicolae Ceaușescu, reopened in the immediate aftermath of the 1989 Revolution), is now named after him.
