Atanasoff Berry Computer

The Atanasoff Berry computer, the ABC, was the first automatic electronic digital computer. Conceived in 1937, it was built at Iowa State College by the mathematics and physics professor John Vincent Atanasoff with the help of graduate student Clifford Berry. It was not programmable, which distinguishes it from more general machines of its era, and in the 1973 decision of Honeywell v. Sperry Rand a federal judge found that Eckert and Mauchly did not themselves first invent the automatic electronic digital computer but derived that subject matter from Atanasoff, the finding at the center of computing's great priority dispute.
