Gustave Caillebotte
Jacques Legrand was one of the founders on 14 June 1875 of the Société Française de Timbrologie, one of the most important philatelic institutions in France, and served as its first secretary. Arthur de Rothschild became its president. Early members included Arthur Maury, despite his disagreement with Legrand over the word philately, and the painter Gustave Caillebotte.
