Albert Nijenhuis (1926 – 2015) was a Dutch-American mathematician who specialized in differential geometry and the theory of deformations in algebra and geometry, and later worked in combinatorics. His early work was in the area of differential geometry. After 1964, his interests shifted to combinatorics. Much of his work was done with Herbert S. Wilf, with whom he published a book in 1975. After retiring, his interest in differential geometry was rekindled. His last conference presentation and paper were presented when he was nearly 70.
