He received his Ph.D. from the University of Warsaw, in 1930, in Poland. Stefan Mazurkiewicz was his thesis advisor. He also received a Ph.D. from Paris University, in 1935; this time Maurice Fréchet was his thesis advisor. He joined the University of Kansas in 1951, where he retired in 1977. He was a Summerfield Distinguished Scholar from 1964 to his death.
He introduced, together with Prom Panitchpakdi, the injective metric spaces under the name of "hyperconvex metric spaces". Together with K. T. Smith, Aronszajn offered proof of the Aronszajn-Smith theorem. Also, the existence of Aronszajn trees were proven by Aronszajn. He also has a fundamental contribution to the theory of Reproducing kernel Hilbert space, the Moore-Aronszajn theorem is named after him 1.
