...described the computer--a machine that could perform logical functions based on whatever instructions were fed to it--and then proceeded to help build one in the early 1940s that cracked the German wartime codes. His concepts were refined by other computer pioneers: John von Neumann, John Atanasoff, J. Presper Eckert and John Mauchly...
...John Mauchly and J. Presper Eckert build ENIAC, the first fully electronic computer...
...years, ENIAC's principal creators, the late John Mauchly and J. Presper Eckert, held the unchallenged title of inventors of the modern computer--until an obscure physicist named John Atanasoff came forth to dispute their claims. In the late 1930s, while teaching at Iowa State College, he and a graduate student named Clifford Bell began building a device that would allow them to solve large linear algebraic equations. Their machine, later called ABC (for Atanasoff Berry Computer), incorporated a number of novel features, including the separation of data processing from memory, and relied on binary numbers instead of ENIAC...
...DIED. J. PRESPER ECKERT, 76, co-inventor of the first fully electronic digital computer; in Bryn Mawr, Pennsylvania. In 1943 Eckert and the late John W. Maulchy created the eniac (electronic numerical integrator and computer), a 30-ton leviathan that was 1,000 times as speedy as the standard calculators of its day, making it invaluable for plotting the trajectory of artillery shells-and for designing the first atom bomb...
