Dayton is a city in Ohio and the county seat of Montgomery County. It was founded on 1 April 1796 by 12 settlers from Cincinnati, and the city was incorporated in 1805. Dayton became a center of manufacturing in the early 1900s, and the first electric cash register was invented in Dayton in 1906. Between the 1940s and 1970s, the city was hit by suburbanization, and its population declined in the 1980s due to the loss of manufacturing jobs and the decentralization of the urban area. In 2015, Dayton had a population of 140,599 people.
