Albert Nijenhuis (born November 21, 1926 in Eindhoven ; † February 13, 2015 ) was a Dutch-American mathematician .

Nijenhuis was 1,952 at January Arnoldus Schouten at the University of Amsterdam PhD ( Theory of the geometric object ), and was then in 1952/53 at Princeton University and from 1953 to 1955 at the Institute for Advanced Study (and again in 1961-62, when he Guggenheim Fellow was ). 1955/56 he was an instructor at the University of Chicago . In 1956 he became an assistant professor and later professor at the University of Washington . In 1963 he became a professor at the University of Pennsylvania , where he retired in 1987. Among other things, he was visiting professor at the University of Geneva (1967/68), at Dartmouth College (1977/78) and 1964/64 Fulbright Lecturer at the University of Amsterdam.

Nijenhuis dealt with combinatorics including algorithms, global and local differential geometry and the theory of deformations in algebra and geometry. Various Lie algebraic structures are named after him (Frölicher-Nijenhuis bracket, Nijenhuis-Richardson bracket, Schouten-Nijenhuis bracket).

In 1958 he was invited speaker at the International Congress of Mathematicians in Edinburgh ( Geometric aspects of formal differential operations on tensor fields ).

He had been married since 1955 and had four children. Nijenhuis was a US citizen . He was a corresponding member of the Royal Netherlands Academy of Sciences and a Fellow of the American Mathematical Society .
