Web1 Hilbert's basis theorem (1888) is usually stated as: "If R is a Noetherian ring, then R [X] is a Noetherian ring." This could not be the original formulation of the theorem since Noetherian rings were named after Emmy Noether, who lived from 1882 to 1935. Do you know the original formulation of the theorem?
