Biography

Popoviciu was born in Arad in 1906, and attended high school in his hometown, the school which is now the Moise Nicoară National College. He graduated from the University of Bucharest, and got his doctorate in 1933 under Paul Montel from Paris-Sorbonne University.[3]

On June 4, 1937 Popoviciu was elected a corresponding member of the Romanian Academy of Sciences. In November 1948 he was elected a corresponding member of the Romanian Academy. He became full member of the mathematical sciences section of the Academy on March 20, 1963.

He married his former student, Elena Moldovan Popoviciu, in 1964; she also became a notable functional analyst.[4] He died in 1975 in Cluj-Napoca, and is buried in the city's Hajongard Cemetery.
