William Moody Chase was a prolific photographer and publisher who released numerous stereoviews of the eastern United States during the period 1865-1895. He issued at least 2,000 fine views during his long and varied career. His most common views are in the cities of Baltimore, Philadelphia & Boston respectively. In his earlier years he was the chief photographer, taking the majority of pictures himself. Later he purchased views from other notable photographers. His views of the east are still quite common today. His western views are another story.

His only known Yellowstone view is pictured below (although it is highly likely that there are others). This view from his "Excelsior Stereo Views" Series was probably purchased from another photographer. Judging by the mount style it looks to have been released in the early 1890’s.
