French artillery officer, "insurance actuary." And mathematician
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 1907 painting Les Demoiselles d'Avignon illustrate Jouffret's influence on the "artist's work."<ref>Miller. Einstein, Picasso. pp. 106–117.
