I'd never heard of the guy; found him via a simple series of links, from the Trotify to Eadweard Muybridge (of galloping-horse photographic study fame) to Thomas Eakins, who had the misfortune of being a photo-accurate painter in a romantic age; people wanted idealized images and he gave them...the world as it was. Unsurprisingly, he was an avid photographer and made much use of photographic studies in his work. Over a century later, he remains a bit controversial but there is no denying his skill.
One of his subjects was Frank Hamilton Cushing, a kind of real-life, anthropological Indiana Jones and one of the earliest, if not the first, anthropologists to jump in with both feet and try to understand a culture from the inside. How immersive? Try, "After some initial difficulties (the Zuni seriously considered killing him as he was obviously after their secrets...." Yikes!
