1937–A Computer Without Mechanics

computer without mechanicsA professor of physics and mathematics at Iowa State University, J.V. Atanasoff, attempts to build the first computer without mechanical components such as gears, cams, belts or shafts. Atanasoff, together with his assistant, graduate student Clifford Berry, creates the first electronic digital computer, the Atanashoff-Berry Computer (ABC). The machine was not programmable, being designed only to solve systems of linear equations. The ABC pioneered important elements of modern computing, including binary arithmetic and electronic twitching elements, but its special-purpose nature and lack of a changeable, stored program distinguishes it from modern computers.
