The Stephen Hoffman Papers document Hoffman’s career as a
mathematician, particularly as a graduate student at Yale in the early 1950s.
Biographical Note
Stephen P. Hoffman, Jr. was an American mathematician. He was born April
10, 1926 in Connecticut, where he attended high school at Norwich Free Academy. His undergraduate and
graduate education took place at Yale University, where he received his bachelor’s (1949), master’s
(1951), and doctoral (1957) degrees, all in mathematics. His doctoral thesis was entitled “Second-Order
Linear Differential Operators Defined By Irregular Boundary Conditions,” which he completed under
Shizuo Kakutani and Jacob T. Schwartz.

Hoffman taught at the Polytechnic Institute of Brooklyn while completing his doctoral work. In 1957, he
began teaching at Trinity College in Hartford, Connecticut. In the mid-1960s, he taught at State
University of New York (SUNY) Cortland, possibly serving as chair of the mathematics department from
1967-1968. He moved to Bates College in Lewiston, Maine, in September 1968, where he was hired as chair
of the mathematics department. A mathematical analyst, Hoffman taught courses in real analysis, as well
as first-year calculus.

Hoffman published several textbooks, including

Basic Analysis (1959),
Modern Intermediate Algebra with Margaret Frances Willerding (1969), and
Advanced Calculus (1970). He was well-known in mathematical circles and
was friends with several prominent mathematicians, including Gian-Carlo Rota and Henry Pollak. Upon
retiring from Bates in the early 1980s for health reasons, Hoffman moved to Hawaii. He passed away in
1985.
Scope and Contents
The Stephen Hoffman Papers document Hoffman’s career as a mathematician, particularly as a graduate
student at Yale in the early 1950s. The bulk of the collection consists of Hoffman’s notes, both
handwritten and typed, from courses he took at Yale. These notes describe courses by Warren Ambrose,
G. A. Hedlund, Einar Hille, Nathan Jacobson, and Shizuo Kakutani. Also included for many courses are
final examinations and term papers written by Hoffman.

The collection also contains some typed draft manuscripts, including Nathan Jacobson’s

Lectures in
Abstract Algebra, Vol. 2: Linear Algebra and a work by Hoffman on real variables.
