(From Wikipedia): Friedrich Speidel sent his three sons, Albert, Edwin and Eugene to America to establish a branch of the family’s jewelry chain manufacturing business. The Speidel Chain Company was officially founded in the United States in 1904.
By 1912 the Speidel brothers hired the architectural firm Monks and Johnson to design the company’s first headquarters. The five-story building, with its European-style front, was originally called the Doran-Speidel Building.
In 1912 Edwin Speidel went on to found the Automatic Chain Company, which produced neck chain, chain-by-the-foot, and watch bracelets, most of their output being sold to watch manufacturers such as Bulova.
At first, only chain was made in the new facilities. During the 1920s, costume jewelry and watchbands were added to the line.
