J. Presper Eckert – 1919-1995

With his University of Pennsylvania professor, John W. Mauchly, Eckert created, in 1946, ENIAC (Electronic Numerical Integrator and Computer), the first allelectronic (not electromechanical) digital computer. Commissioned by the U.S. government, it was used primarily for military applications and contained, in rudimentary form, all of the circuitry employed in modern computers.
