1946 THE ENIAC COMPUTER

J. PRESPER ECKERT AND JOHN MAUCHLY DESIGN AND BUILD THE ENIAC COMPUTER. IT USED 18,000 VACUUM TUBES AND COST $500,000 TO BUILD.

Dr. John Eckert was a graduate of Pennsylvania who was important to the development of the computer because together with John W. Mauchly, the two of them invented the first electronic digital computer. This computer was called the ENIAC which stood for Electronic Numerical Integrator and Computer. This first in electronic computing was made from 500,000 hand soldered connections that used punched cards to store data. This was very primitive compared to the wondrous microprocessors that we have today. The motivation for building this computer was the U.S. Army, as the military needed something to do its increasingly demanding calculations.
