East of Corning, the Chemung River runs directly through downtown Elmira. Founded in the early 1800s, Elmira’s central location in the state made it a hub of transportation and industry. Canals and railroads passed through Elmira, and by the turn of the 19th Century, it had become a waypoint connecting commercial centers in Rochester and Buffalo with Albany and New York City.
During the Civil War, the railroad junction also made Elmira a military depot, a draft rendezvous, and a notorious prisoner of war camp for captured Confederate soldiers. In the later part of the century, Mark Twain spent summers in Elmira with his wife's family, and is buried in the city’s Woodlawn Cemetery.
In the 20th Century, Elmira became a seat of manufacturing and retail. In 1935, Elmira Industries was formed, with the intention of drawing more industry to the area. Among its earliest successes was the Remington Rand typewriter corporation, a major employer. During World War II, a reported 90% of the population was involved in manufacturing, staffing 92 different factories and filling $80 million in war contracts (equivalent to $2.5 billion in 2022).
By the 1970s, national economic trends began to hurt Elmira. Many of its large employers closed their factories or relocated, looking for cheaper production costs.
The flooding on June 23, 1972, dealt the local economy a blow from which it never truly recovered. The river rose, washed out bridges and cut the city in half. Huge portions of the city were heavily damaged, particularly the businesses on Water Street. Most of these buildings were torn down after the flood and were never rebuilt.
