The IBM 805 Test Scoring Machine was a machine sold by IBM beginning in 1937. The device scored answer sheets marked with special "mark sense" pencils. The machine was developed from a prototype developed by Reynold Johnson, a school teacher who later became an IBM engineer. That machine and its descendants have been in use ever since.
