This was the first look into the Inuit world. It essentially was the first documentary made. In the early 1900’s Robert J. Flaherty went on an expedition to the Canadian Arctic by the Hudson Bay. During his time spent with the Inuit people (whom he referred to as Eskimos) he documented the experience with a Bell-Howell Camera and a portable developing and printing machine. During expeditions between 1910 and 1913 Flaherty compiled enough footage to put together a short film. The film burned and Flaherty decided to go back with a film crew and recapture what he had lost of raw footage. 1914 through 1916 Nanook was created. I say created instead of filmed to make the differentiation between the earlier raw film and the product of direction that was the footage used in the final cuts.
