History

Colonial and Revolutionary era

Derby was settled in 1642 as an Indian trading post under the name Paugasset by John Wakeman of New Haven, though fur traders had been in the area before and Native Americans had lived there for centuries. In 1651, the first year-round houses were completed, at which time the New Haven Colony had recognized Paugasset as a town. The residents of the town of Milford protested Paugasset’s recognition as an independent town and, as a result, the order was rescinded and Paugasset returned to the Milford jurisdiction. In 1675, the former plantation of Paugasset was admitted as the township of Derby by the state legislature, named after Derby, England. Derby was incorporated on May 13, 1775.

1800s

In 1836, the Colman brothers began the Birmingham Iron Foundry on the corner of Main Street and Water Street. It employed between 100 and 125 people, and was one of the many manufacturing businesses thriving in the city in the 1800s. In 1927, the company merged with Farrel Corporation of nearby Ansonia and was renamed Farrel-Birmingham Corporation. The Derby facility closed and was razed in 2000 to make way for a Home Depot. The Ansonia division is still in business, and opened their new plant in the Fountain Lake Commerce Park in 2017.

In the 19th century, corsets and hoop skirts were manufactured in the city. The Kraus Corset Factory is the oldest major factory building to survive from Derby’s corset manufacturing period. It was built by Sidney A. Downs, opened in 1879, and expanded in 1910. In 1987 it was added to the National Register of Historic Places. In the 1990s it was converted to apartments and underwent a second addition; a first floor parking garage and three stories of apartments were added on the north side along Roosevelt Drive (Connecticut Route 34).

In 1872, the Derby Silver Company began production. In 1898, the company became a division of the International Silver Company headquartered in Meriden, but continued making silver with its brand name until 1933.

1900s

Charlton Comics, a comic book publishing company that existed from 1944 to 1986, was based in town.
