First electronic digital computer

In 1973, a US Federal Judge signed his decision following a lengthy court trial which declared the ENIAC patent invalid and belatedly credited physicist John Atanasoff with developing the first electronic digital computer, the Atanasoff- Berry Computer or the ABC. Built in 1937-42 at Iowa State University by Atanadoff and a graduate student, Clifford Berry, it introduced the ideas of binary arithmetic, regenerative memory, and logic circuits. These ideas were communicated from Atanasoff to John Mauchly, who used them in the design of the better-known ENIAC built and patented several years later.
