Endwell is a hamlet (and census-designated place) located in the town of Union in Broome County, New York, United States.

The main road along the north bank of the Susquehanna River, existing since colonial times and long before as an Indian trail, passed just to the south.

[citation needed] Several businesses were located near this commercial site from 1850 to 1950, including a creamery (dairy plant) reflecting the predominantly dairy-based economy in the immediate surrounding area at the time.

The Town Council of Union has been the local government of what is now Endwell since 1791, although over the years some functions have been taken over by Broome County (poor relief/social services) and by New York State (policing).

[citation needed] Hooper School (now demolished), located a quarter mile west of the depot on the north side of East Main Street, provided primary education (kindergarten-8th grade, K-6 after 1954) for area children from 1923 to 1971.

It was in fact a dense forest pierced by Patterson Creek, and the original industry in Endwell dating back to about 1800 was logging.

By 1860 economic activity in the area was based on dairy farms along Hooper and Farm-to-Market Roads, second-growth logging, and the railroad depot.

[citation needed] At this time, the only roads in the area were Hooper, Farm-to-Market, Taft, Twist Run, and East Main (current names).

During the 1890s, significant commercial and residential development began along the East Main Street corridor (State Route 17C), including a horse-drawn streetcar line, which connected the growing villages of Johnson City and Endicott.

For a nominal fee, subsidized by Reed Freeman, a wealthy Binghamton clothing manufacturer, the Chautauqua Assembly at Carmel Grove combined what we would call today a week-long "resort" experience with a stimulating series of lectures by nationally known figures of the time, along with popular musical and theater acts.

Capable of accommodating a thousand guests in rows of cabins over the hillside, this was a popular summer vacation destination for residents of Binghamton, central New York, and northeastern Pennsylvania for many years.

[citation needed] Endwell appears as it does today because of the rapid growth of nearby Endicott-based International Business Machines (IBM), a computer manufacturer, during the 1940-1970 period.

This created a demand for housing which quickly converted Endwell from a hamlet at the intersection of Hooper Road and State Route 17C into the large residential area it is today.

[citation needed] A few big names in sports have lived or were born here, including Mike Dunham (longtime NHL goalie, now goalie coach for the New York Islanders) and Isaiah Kacyvenski (starter for the Seattle Seahawks for 5 years-and was Special Teams captain for Seattle during their 2005 Super Bowl appearance).
