In 1941, a position of professor at the University of Bucharest opened up, and Moisil applied for it. However, Gheorghe Vrânceanu, Dan Barbilian, and Miron Nicolescu also applied for the position, and Vrânceanu got it. Moisil approached the Ministry of Education, arguing that it would be a great opportunity for mathematics in Romania if all four could be appointed. As a result of his appeal, all four mathematicians were hired. Moisil moved to Bucharest, where he became a Professor in the School of Mathematics (later the School of Mathematics and Computer Science) at the University of Bucharest, on 30 December 1941.
