Wadsworth's cipher system involved a set of two disks, one inside the other, where the outer disk had the 26 letters of the alphabet and the numbers 2–8, and the inner disk had only the 26 letters.
Wadsworth's cipher was a cipher invented by Decius Wadsworth, a Colonel in the Ordnance Corps of the United States Army.
