Jacobus "Koos" Verhoeff (20 February 1927 – 19 March 2018) was a Dutch mathematician, computer scientist, and artist. He is known for his work on error detection and correction, and on information retrieval. 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.
