ENIAC – 1946:
ENIAC I (Electrical Numerical Integrator And Calculator). The U.S. military sponsored
their research; they needed a calculating device for writing artillery-firing tables (the
settings used for different weapons under varied conditions for target accuracy).
John Mauchly was the chief consultant and J Presper Eckert was the chief engineer.
Eckert was a graduate student studying at the Moore School when he met John Mauchly
in 1943. It took the team about one year to design the ENIAC and 18 months and
500,000 tax dollars to build it.
The ENIAC contained 17,468 vacuum tubes, along with 70,000 resistors and 10,000
capacitors.
