Paris, 1820. A fine lithograph (30.0 x 21.5 cm).

The French priest René-Just Haüy was the most important mineralogist and crystallographer of the 18th century. The plate caption reads: Institut Royal de France, Acad. des Sciences (Minéralogie), Chev. de la Légion d'Honneur. The artist, Julien-Léopold "Jules" Boilly (1796 -1874), published both an "Iconographie de l'Institut Royal de France" (1820-1821) and an "Album de 73 Portraits-Changés Aquarelles des Membres de I’Institute" (1820). Both are very rare. This fine engraving was taken from the first work. Light, even foxing throughout.
