J.E. Caldwell & Co.
The company of J.E. Caldwell & Co. was a landmark jeweler in Philadelphia, highly respected for its exquisite jewelry and silverware. But, like many jewelers, it was in creating jewels during the Art Nouveau and Art Deco periods that this jeweler would make its lasting mark. Upon his death in 1881, Caldwell's son, James Albert, took over the reins. In turn, his son, James Emmott, his grandfather's namesake, succeeded him. The firm changed hands many times. In 1924, J.E. Caldwell moved into the majestic space at 1339 Chestnut Street. The store itself was a work of art, boasting 17 French-cut crystal chandeliers suspended from 20-foot ceilings and an interior designed by architect Horace Trumbauer in the French Regency style. The elaborate setting dovetailed perfectly with the tastes of the jeweler's wealthy clientele. Philadelphia's socialites with a yen for European-style jewelry were the desired audience.
