E. & H. T. Anthony & Co.
1841 - 1902
The firm of E. & H. T. Anthony was in business from 1841 to 1902 and for most of that time located at 501 Broadway, New York City. They succeeded the Lewises' as the leading supplier of photographic supplies, cameras, stereoscopes and stereoviews in the US. They were importers of stereoscopes from Europe until the Holmes/Bates viewer became the instrument of choice for viewing stereoviews. They were one of the largest publishers of stereoviews for most of the years they were in business. They also sold domestic viewers made by Lee and Beckers.
