J. Presper Eckert Jr. was an American engineer who created one of the first general-purpose electronic computers. This computer, the ENIAC (Electronic Numerical Integrator and Computer) was a digital machine that was the prototype for most computers in use today.
In 1946, Eckert worked with John W. Mauchly to fulfill a government contract to build a digital computer to conduct military calculations for the U.S. Army. In 1949, they began manufacturing their BINAC computer, which they followed with a business oriented computer called the UNIVAC in 1951. These models were put to many uses and spurred the growth of the computer industry. By 1966 Eckert held 85 patents, mostly for electronic inventions.
