The Computers of John Presper Eckert & John Mauchly

  • The ENIAC Computer
    In 1946, John Mauchly and John Presper Eckert developed the ENIAC I (Electrical Numerical Integrator And Calculator).
    In August 1944, John Mauchly and J Presper Eckert proposed the building of a new machine called the electronic discrete variable automatic computer or EDVAC. The EDVAC was the first internally stored program computer to be built, a major improvement over the ENIAC.
