The Bristol Brass Company was founded as the Bristol Brass and Clock Company in 1850, the creation of sixteen industrialists from Bristol clock and Waterbury brass interests who hoped to profit in the booming clock industry of Bristol, CT. Although the company never manufactured clocks, only the brass mechanisms for the timepieces, it was many years before it changed its name to Bristol Brass Company. It was the largest employer in Bristol, with 375 employees by 1880. Its mainstay was the production of brass for automobiles. The company thrived during the years of World Wars I and II, making shell cases for the military. The post-war economy brought a change in the company's fortunes. The amount of brass used in automobiles declined swiftly, and foreign competition eroded the company's clientele. Bristol Brass closed its doors in December 1982, after 132 years as a major part of the Bristol economy.
