The Ausonia Clock Company was one of the major 19th century American clock manufacturers. In 1844 the Ansonia Brass Company is formed by Anson Green Phelpsin Connecticut, and then a subsidiary company was later formed in 1850 by clockmakers T.Terry and F.C.Andrews; the Ausonia Clock Company.
During the 1870’s moved most of its production in New York, where the production effectively started in 1880, before then, clock were produced exclusively in Connecticut. In 1883, the Connecticut factory was closed down since the one in New York was rebuilt in 1881 after it had burnt down the year before, with a greater capacity. Many offices around the world were opened and more than 225 different clock models were produced, reaching 440 models by 1914. During the ‘20s though, the company started declining, the number of models fell to 136, and only 47 by 1927. They started selling their timekeeping machinery and working tools to a Soviet government trading company Amtorg, and machineries and skilled workers moved out in Moscow to keep on working in the watch industry.
In 1969, the rights to the use of the name, trademarks, and goodwill were transferred to Ansonia Clock Co., Inc.
