Jean-Baptiste Gustave Le Gray (August 30, 1820, Villiers-le-Bel, Val-d’Oise – July 30, 1884)[1] has been called “the most important French photographer of the nineteenth century” because of his technical innovations in the still new medium of photography, his role as the teacher of other noted photographers, and the extraordinary imagination he brought to picture making.”
