Timothy O’Sullivan is best known for his haunting battlefield images of the American Civil War, but after the war O’Sullivan continued his rich and lasting photography career. O’Sullivan joined the United States Geological Exploration of the Fortieth Parallel in 1867. From 1871 to 1874 he took part in a survey west of the 100th meridian. O’Sullivan’s photographs of the Southwest were used to recruit settlers, but more importantly they provide a glimpse into the lives of the Southwestern American Indian tribes, and a peek into pre-industrialized western landscapes.

The following animated gif wigglegrams were created from scans of original stereographs from O’Sullivan’s photographs using the New York Public Library’s Stereogranimator website (created by Joshua Heineman).
