The New Haven Clock Company was founded in 1853 by Hiram Camp in New Haven, Connecticut, United States. Initially, the company manufactured clock movements and components for the clockmaking business of his uncle, Chauncey Jerome, an important pioneer of the American clock industry. Following the financial collapse of the Jerome Manufacturing Company, New Haven acquired its production facilities in 1856 and began manufacturing complete clocks. The company became one of the leading American clock manufacturers of the late nineteenth and early twentieth centuries. Its products included wall clocks, mantel and table clocks, alarm clocks, and later pocket watches and wristwatches. Its clocks were also sold internationally. At its peak, the factory complex comprised numerous buildings and employed more than a thousand people. After the Second World War, the company faced increasing economic difficulties. Production ceased in 1956. Parts of the historic factory complex in New Haven survive today and were added to the United States National Register of Historic Places in 2017.
