Simion StoiloworStoilov (14 September [O.S. 2 September] 1887 – 4 April 1961)[1] was a Romanian mathematician, creator of the Romanian school of complex analysis, and author of over 100 publications.
He was born in Bucharest, and grew up in Craiova. His father, Colonel Simion Stoilow, fought at the Battle of Smârdan [ro] in the Romanian War of Independence. After studying at the Obedeanu elementary school and the Carol I High School, Stoilow went in 1907 to the University of Paris, where he earned a B.S. degree in 1910 and a Ph.D. in Mathematics in 1916. His doctoral dissertation was written under the direction of Émile Picard.[2]
He returned to Romania in 1916 to fight in the Romanian CampaignofWorld War I, first in Dobrudja, then in Moldavia.[3] After the war, he became professor of mathematics at the University of Iași (1919–1921) and the University of Cernăuți (1921–1939). He was an Invited Speaker of the International Congress of Mathematicians in 1920 at Strasbourg, in 1928 at Bologna, and in 1936 at Oslo. In 1928 he was awarded the Legion of Honour, Officer rank.[4] In 1939 he moved to Bucharest, working first at the Polytechnic University of Bucharest, and from 1941 at the University of Bucharest, serving as rector from 1944 to 1946 and as dean of the Faculties of Mathematics and Physics from 1948 to 1951.
From 1946 to 1948, he served as Romanian ambassadortoFrance. In 1946 he was a member of the Romanian delegation at the Paris Peace Conference, headed by Gheorghe Tătărescu. 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. In 1946 he was awarded the Order of the Star of Romania, Grand Officer rank and in 1948, the Order of the Star of the Romanian People's Republic, Second class.[4]
Stoilow was elected corresponding member of the Romanian Academy in 1936, and full member in 1945, and later became president of the Physics and Mathematics section of the Academy.[1] In 1949 he was the founding director of the Institute of Mathematics of the Romanian Academy, serving in that capacity until he died. 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. Some of the first Romanian topologists who obtained their candidate’s theses were Stoilow’s students Tudor Ganea, Israel Berstein [ro], Aristide Deleanu [ro], Valentin Poénaru, and Kostake Teleman [de].[5]
In 1952, Stoilow was awarded the Order of the Star of the Romanian People's Republic, First class.[4]
Stoilow died in Bucharest in 1961 of a brain stroke. He was cremated at the Cenușa crematorium. 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. The Simion Stoilow Prize is awarded every year by the Romanian Academy.
