[3] He studied at the Massachusetts Institute of Technology (MIT), receiving a Bachelor of Science in Mathematics in 1952.

After that, he attended Princeton University, receiving a Masters in 1953 and a Ph.D. in Mathematics in 1955 under the direction of his thesis advisor Kunihiko Kodaira (On the Quotient of a Complex Analytic Manifold by a Discontinuous Group of Complex Analytic Self-Homomorphisms).

In addition, he often visited Moscow and Saint Petersburg and spoke fluent Russian.

In 1962, he was an invited speaker at the International Congress of Mathematicians held in Stockholm (On the moduli of Abelian varieties with multiplications from an order in a totally real number field).

His doctoral students include Paul Monsky, Timothy J. Hickey, and Daniel Bump.
