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 on information retrieval.^[4] He has also held exhibitions of his mathematically inspired sculptures.

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

His son, Tom Verhoeff, is a mathematician and computer scientist.
