Jacobus "Koos" Verhoeff (20 February 1927 – 19 March 2018)[3] was a Dutch mathematician, computer scientist, and artist. He is known for his work on error detection and correction, and worked on information retrieval.[4] He has also held exhibitions of his mathematically inspired sculptures.

He was best known for his check-digit Verhoeff algorithm, which is based on the dihedral group of order 10.

He was the father of Tom Verhoeff, also a mathematician and computer scientist.
