History

The area along the Naugatuck River, comprising the present Elm Street section of Ansonia and Derby Avenue section of Derby, was first settled by English colonists in 1652; it was originally a part of the township of Derby. Early settlers developed subsistence farming, and used the river for sawmills and gristmills.

In 1844, Anson Green Phelps (1781–1853), a merchant and philanthropist, wanted to expand the old borough of Birmingham (the present downtown of the city of Derby) to the north along the west side of the Naugatuck River to enable industrial development. Unable to purchase the land from its owner, in 1844 Phelps acquired land along the east side of the river; today this is Ansonia’s downtown section. A canal was dug for river power to drive the factories and businesses in the new industrial village, which Phelps named “Ansonia”. He wanted to name the industrial village as “Phelpsville”, but learned there was another village in the region by that name. As suggested by a friend, Phelps changed his first name to create the name “Ansonia”.

As industry developed, soon Ansonia became the most populous area of Derby, boasting many factories. The state chartered Ansonia as a borough of Derby in 1864 and amended it in 1871, granting full municipal privileges. In 1888, a petition was circulated in the borough of Ansonia for the purpose of becoming a separate township from Derby. In 1889 the State General Assembly granted the separation, constituting the Borough, Hilltop, West Ansonia, and Elm Street areas as a separate town known as Ansonia. This was the 168th township in the state of Connecticut. In 1893, Ansonia was incorporated as a city, consolidating with the coterminous Town and the old borough.

By the end of the 19th century, the city had manufacturers of heavy machinery, electric supplies, brass and copper products, and silk goods. Ansonia, Derby, Shelton, Seymour, and Beacon Falls formed one of the most important industrial communities in the state.

Invention of America’s first bicycle

In 1866, while residing in Ansonia, inventor Pierre Lallement, a native of Pont-a-Mousson, France, submitted a patent application for the first pedaled (rotary crank mechanism) bicycle.

20th century to present

Ansonia suffered grievous damage in the Flood of 1955 on August 19, when the Naugatuck River flooded due to heavy rain from Hurricane Diane. Submerging the land along the river, the flood destroyed many houses and businesses. The high river waters swept away Maple Street Bridge, one of two bridges linking the east and west sides of Ansonia. After the inundation, the authorities erected a flood wall along the east bank of the river to protect the city’s factories and Main Street. On the west bank, federal public housing was built to replace blocks of destroyed homes and businesses on Broad Street, now known as Olson Drive.

In the decades following the flood and suburbanization, Ansonia’s Main Street fell into decline as retail shoppers decamped to the Ansonia Mall at its far end. (This was replaced with the Ansonia Shopping Center in the 90’s) Later other malls attracted shoppers to nearby Milford, Trumbull, and Waterbury. Since the late 20th century, Main Street has been enlivened by the opening of several antique stores, a wine bar, a coffee shop, a Polish delicatessen, and other retail businesses. Main Street now has a Target store near the currently abandoned building that housed American Brass Co. Wire Mill, later Farrel Corporation.

For years, Ansonia had a daily newspaper, the “Evening Sentinel”, that enjoyed a wide readership throughout the Naugatuck Valley. However, the parent company of the Connecticut Post bought the Sentinel in the 1980s and quickly closed it, despite their promises not to do so. Allegedly, the “Post” wanted to consolidate their position as the region’s main newspaper. To provide an alternative, a non-profit, online-only news site, named The Valley Independent Sentinel in honor of the historic paper, has been organized and launched June 22, 2009.

In the early morning hours of November 6, 1960, Senator John F. Kennedy’s presidential campaign motorcade stopped on its way to Waterbury for the candidate to make an appearance and brief address in front of City Hall. He drew thousands to downtown, many with transistor radios tuned to live reports on WADS of Senator Kennedy’s progress towards Ansonia. President Kennedy returned to Ansonia on October 17, 1962, while on his way to Waterbury, but did not stop here.

President George H. W. Bush paid a visit to Ansonia by helicopter during the 1992 presidential election campaign. He was running far behind schedule due to severe weather damage to a large area of New Jersey. He arrived late and delivered a truncated speech, causing many residents in this heavily Democratic area to feel he had slighted their city.

In 2000, the Lower Naugatuck Valley, which includes Ansonia, was named an “All America City” by the National Civic League.

In May 2001, a wind-driven fire destroyed the Latex Foam Company building, a very large rubber plant along the Naugatuck River in downtown Ansonia. The fire gutted the 284,000-square-foot (26,400 m) building, which was the workplace of 250 people. Firefighters from multiple counties fought the fire tirelessly for five days. Lingering clouds of foul-smelling smoke spread over the city and nearby communities, and chemical runoff produced by the fire unbalanced the ecosystem of the nearby river. The aforementioned Target store was constructed on the empty lot, opening in July 2007. [1] Following the fire, the Latex Foam Company purchased a vacant plant off Route 110 in nearby Shelton and resumed production.

Geography

According to the United States Census Bureau, the city has a total area of 6.2 square miles (16.0 km), of which 6.0 square miles (15.6 km) is land and 0.15 square miles (0.4 km), or 2.72%, is water. The city is bisected by the Naugatuck River and spreads out from the river’s banks up the hills—some quite steep—of the river valley. On the west side of the river, the city abuts Derby and Seymour along Silver Hill. On the east side, the city’s Hilltop neighborhood meets Woodbridge.

The land along the river is mostly given over to factory sites (both operational and defunct), with an area of wooded land on the west bank close to the city’s northern boundary that belongs to the American Brass Company. In the early 1990s, this site was proposed by Texas company American Ref-Fuel for a solid waste-to-electric energy cogeneration plant. The proposal was controversial, and protests by residents resulted in its defeat.

Residential housing occupies most of the land in Ansonia, chiefly one- or two-family houses on plots of a 1/4 acre up to an acre. Larger houses on larger plots are found in the Hilltop neighborhood. The Ansonia Nature Center on Hilltop preserves some open fields and woodlands and is a favorite for school trips.

An airport once operated on Hilltop on a grass field, at the eastern edge of the city. During the Cold War, the United States military deployed Nike missiles in silos at the airport. Since the military released the airport grounds for other uses, developers have built residential housing there. The Nike base is now adapted as a horse farm with riding stables; few reminders of its former operations remain.

Neighborhoods

Library District – The neighborhood surrounding the Ansonia Library. Just east of downtown on top of the cliff. Includes the residential neighborhood between State Street and Beaver Street including South Cliff Street, North Cliff Street, Mott Street and Cottage Avenue. Contains mostly single-family historic Queen Anne Victorian homes. While now predominantly middle class, this area was settled early in Ansonia’s history and was once home to many of the wealthy industrial families of Ansonia.
