...The Archives de la Planète gather 4,000 stereoscopic plaques, 72,000 autochromes (constituting therefore one of the largest collections in the world) and around 183,000 meters of film, which amount to more than 100 hours of projection. They document forty-eight countries in the world, from every continent except Oceania. They were shot between 1912 and 1931 by five cameramen under the close supervision of the French geographer Jean Brunhes (1869-1932), chosen by Albert Kahn to oversee the constitution of the archives from their very beginning. To these films one should add an additional 17,000 meters of newsreels and other material bought from Gaumont and Pathé. The collection's purpose was, to quote Kahn, “to put into effect a sort of photographic inventory of the surface of the globe as inhabited and developed by Man at the beginning of the twentieth century.”Amazing.
