Haskell Brooks Curry (
September 12, 1900– September 1, 1982) was an American mathematicianand logician. Curry is best known for his work in combinatory logic; while the initial concept of combinatory logic was based on a single paper by Moses Schönfinkel, much of the development was done by Curry. Curry is also known for Curry's paradoxand the Curry-Howard correspondence. He has the distinction of having two programming languages named after him, Haskell and Curry.
Curry was born on September 12, 1900, in
Millis, Massachusetts, to Samuel Silas Curry and Anna Baright Curry, who ran a school for elocution. He entered Harvard Universityin 1916 to study medicine but switched to mathematics before graduating in 1920. After two years of graduate work in electrical engineering at MIT, he returned to Harvard to study physics, earning a MA in 1924. Curry's interest in mathematical logic started during this period when he was introduced to the Principia Mathematica, the attempt by Alfred North Whiteheadand Bertrand Russellto ground mathematics in symbolic logic. Remaining at Harvard, Curry pursued a Ph.D. in mathematics. While he was directed by George Birkhoffto work on differential equations, his interests continued to shift to logic. In 1927, while an instructor at Princeton University, he discovered the work of Moses Schönfinkel in combinatory logic. Schönfinkel's work had anticipated much of Curry's own research, and as a consequence, he moved to Göttingen where he could work with Heinrich Behmannand Paul Bernays, who were familiar with Schönfinkel's work. Curry was supervised by David Hilbertand worked closely with Bernays, receiving a Ph.D. in 1930 with a dissertation on combinatory logic.cite journal|last=Seldin|first=Jonathan|title=The Logic of Curry and Church]
In 1928, before leaving for Göttingen, Curry married Mary Virginia Wheatley. The couple lived in Germany while Curry completed his dissertation, then, in 1929, moved to State College, Pennsylvania where Curry accepted a position at Penn State College. They had two children, Anne Wright Curry (July 27, 1930) and Robert Wheatley Curry (July 6, 1934). Curry remained at Penn State for the next 37 years. He spent one year at
University of Chicagoin 1931-32 under a National Research Fellowship and one year in 1938-39 at the Institute for Advanced Studyin Princeton. In 1942 he took a leave of absence to do applied mathematics for the US government, just before and during World War II. Immediately after the war he worked on the ENIACproject, in 1945 and 1946. Under a Fulbright fellowship, he collaborated with Robert Feysin Louvain, Belgium. After retiring from Penn State in 1966, Curry accepted a position at the University of Amsterdam. In 1970, after finishing the second volume of his treatise on the combinatory logic, Curry retired from the University of Amsterdam and returned to State College, Pennsylvania.
Haskell Curry died on September 1, 1982 in State College, Pennsylvania.
The focus of Curry's work were attempts to show that
combinatory logiccould provide a foundation for mathematics. Towards the end of 1933, he learned of the Kleene-Rosser paradoxfrom correspondence with John Rosser. The paradox, developed by Rosser and Stephen Kleenehad proved the inconsistency of a number of related formal systems including the lambda calculus and Curry's own system.cite journal|last=Seldin|first=Jonathan|title=The Logic of Curry and Church] However, unlike Church, Kleene, and Rosser, Curry did not give up on the foundational approach, saying that he did not want to "run away from paradoxes." [cite book|last=Barendregt|first=H.P.|title=The Lambda Calculus: Its Syntax and Semantics|publisher=Elsevier|pages=4]
By working in the area of Combinatory Logic for his entire career, Curry essentially became the founder and biggest name in the field. Combinatory logic is the foundation for one style of
functional programming language. The power and scope of combinatory logic is quite similar to that of the lambda calculusof Alonzo Church, and the latter formalism has tended to predominate in recent decades.
He taught at Harvard, Princeton, and from 1929 to 1966, at the
Pennsylvania State University. In 1942, he published Curry's paradox. In 1966 he became professor of mathematics at the Universiteit van Amsterdam.
Curry also wrote and taught
mathematical logicmore generally; his teaching in this area culminated in his 1963 "Foundations of Mathematical Logic". His preferred philosophy of mathematics was formalism (cf. his 1951 book), following his mentor Hilbert, but his writings betray substantial philosophical curiosity and a very open mind about intuitionistic logic.
