Corning is a city in Quincy Township, Adams County, Iowa, United States. The population was 1,635 at the 2010 census. It is the county seat of Adams County. Corning is located just north of the intersection of U.S. Route 34 and Iowa Highway 148.
Corning is perhaps best known as the birthplace of Johnny Carson. Daniel Webster Turner, who was governor of Iowa from 1931 to 1933, was born in Corning on March 17, 1877.
The first European settlers here were a group of French Icarians who came from Nauvoo, Illinois in 1852; they established a community near Lake Icaria, north of Corning in 1854. The new state of Iowa gave the town of "Icaria" a corporate charter in 1860. This community was dedicated to the utopian principles of Etienne Cabet and the democratic principles of the American Revolution and the French Revolution; this small French-speaking community considered themselves to be very patriotic Americans. In the 1860s, the community split between "traditionalists" and "progressives" (the latter favored women's right to vote).
