Did Baron Wilhelm Von Steuben have anything to do with the development of Steuben glass?
Not really. The Steuben Glass Company was founded in 1903 by Frederick Carder in Corning, New York, which is in the County of Steuben, hence the name.
Steuben County is named after Baron Friedrich Wilhelm von Steuben who resided there after being honorably discharged from the American Army in 1784. That's his only connection.
