Edward Sheriff Curtis (1868–1952) dedicated his entire life to a project all his own, to use a camera to preserve the cultural heritage of the indigenous peoples of North America. For three decades, he traveled in every region of the continent, through every kind of terrain and weather, via land or water, in the 50°C heat of the Mojave Desert or the -20°C chill of the Arctic; moving on foot, by horse, wagon, donkey, boat or train, or later by automobile. More than 40,000 photos were produced during those years.
