Ichabod Washburn (1798–1868) was an American Congregational deacon and industrialist from Worcester County, Massachusetts. His financial endowments led to the naming of Washburn College, now Washburn University in Topeka, Kansas and the foundation of Worcester Polytechnic Institute in Worcester, Massachusetts. By 1865, Washburn was co-proprietor (with his son-in-law Philip Moen) of Washburn and Moen Manufacturing Company, the world's largest wire mill. The company manufactured piano wire, crinoline and supports for hoop skirts, wire for fences and other similar products.
