Arther Wesley Van Horn (1860-1931) was a prolific architect of Bismarck, North Dakota. He began as an independent architect in 1883, worked within Van Horn & Loven during 1917-1919, and within Van Horn & Ritterbush Brothers during 1920-1931. The Bismarck-based firm evolved as Ritterbush Brothers during 1931-1974 and subsequently as Ritterbush Associates.
A number of Van Horn's works, alone or as part of the firm, are listed on the U.S. National Register of Historic Places.
