James Emmott Caldwell (1813-1881) trained as a silversmith, jeweler, and watchmaker in New York City before founding his own business in Philadelphia in 1839. The firm acquired a national reputation by winning competitive silver commissions and participating along with Tiffany & Co and Starr & Marcus as one of the three American jewelers to exhibit at the Centennial Exhibition of 1876. Along with Bailey, Banks & Biddle, the firm was a favorite of Main Line Philadelphians, and is known for its refined Edwardian and Art Deco platinum jewelry. A stereoscopic view of Caldwell's opulent store with soaring ceilings and windows reveals it as a two story emporium of precious goods. Visible in the sepia toned image are jewelry-filled long glass cases with velvet stools,and arrrayed with sculptures including busts, herms and full length figures, while behind the glass counters are tall vitrines filled with objets. The image is available in the digital collection of the New York Public Library at
