Patrick Dehornoy (11 September 1952 – 4 September 2019) was a mathematician at the University of Caen who worked on set theory and algebra. He found one of the first applications of large cardinals to algebra by constructing a certain left-invariant total order, called the Dehornoy order, on the braid group. He was one of the main contributors to the development of Garside methods in group theory, leading in particular to a conjectured solution for the word problem of general Artin–Tits groups.
