The sign on the house at 114 Perry Avenue, in the Silvermine section of Norwalk, identifies it as the Ralph Keeler House, built c. 1750. The Keelers were one of the founding families of Norwalk. Also known as the Isaac Camp property, the house has elsewhere been dated to c. 1778. Verneur E. Pratt (1891-1966) moved to Norwalk in the late 1920s and lived in the house. An inventor and entrepreneur, Verneur Pratt converted the adjacent carriage barn (116 Perry Avenue, built c. 1800) into a laboratory in the late 1930s. Pratt invented the Optigraph Reading Machine, an early microfilm reader.
