Esprit Jouffret (15 March 1837 – 6 November 1904) was a French artillery officer, insurance actuary and mathematician, author of Traité élémentaire de géométrie à quatre dimensions (Elementary Treatise on the Geometry of Four Dimensions, 1903), a popularization of Henri Poincaré's Science and Hypothesis in which Jouffret described hypercubes and other complex polyhedra in four dimensions and projected them onto the two-dimensional page. Maurice Princet brought Traite to artist Pablo Picasso's attention. Picasso's sketchbooks for his painting Les Demoiselles d'Avignon illustrate Jouffret's influence on the artist's work.
