Jean Delsarte
Jean Frédéric Auguste Delsarte (19 October 1903, Fourmies – 28 November 1968, Nancy) was a French mathematician known for his work in mathematical analysis, in particular, for introducing mean-periodic functions and generalised shift operators. He was one of the founders of the Bourbaki group. He was an invited speaker at the International Congress of Mathematicians in 1932 at Zürich.
