Nasco was started in 1941 by a vocational agricultural teacher, Norman Eckley. He developed several teaching aids to use in his vocational agriculture classes…teaching aids that were not readily available from any other source. This simple act of filling a classroom need with an appropriate product was to become a way of life for Nasco in years to come.
