Pierre Rene Marie Henri Moul-Lin De La Blanchere, a French naturalist and photographer, born at La Fleche, Sarthe, May 2,1821. After studying the natural sciences, he established himself in Paris in 1855 as a photographer, with a view of applying that art to scientific purposes. He was president during five years of the societe du progres de l'art industriel, and superintended its semi-annual exhibitions in the Champs Elysees. At a later period he was commissioned by the government to execute photographic illustrations of the various types of French fishes and of the management of the piscicultural establishments at Huningen and Concarneau; and these he collected in an album, which attracted much attention at the exhibition of 1807. His principal works are: Repertoire encyclopedique de photographic (a periodical, 6 vols., 1862-7); Nouneau diction-naire general des peches (4to, illustrated); Les ravageurs des forets (1865); Lapeche aux bains de mer, and Voyage au fond de la mer (1868).
