ENIAC, Electronic computer at University of Pennsylvania, United States.
ENIAC is an electronic computer at the University of Pennsylvania made up of 40 panels and thousands of vacuum tubes. The machine is enormous in size and requires substantial electrical power to operate.
ENIAC was developed by John Mauchly and J. Presper Eckert at the Moore School of Electrical Engineering and completed in 1946. It represented the first general-purpose electronic computing machine.
Six women mathematicians figured out how to program this machine by studying its blueprints and then wrote the first operating manual for it. Their work shaped how computers would be used for decades to come.
The computer is located on the university campus and open to visitors during regular hours. It is helpful to check ahead for guided tours and to plan your route to the specific building where it is housed.
Only four of the original 40 panels remain on display in the engineering building, showing just a fraction of the machine's original size. These few remaining pieces give visitors a sense of how massive the entire installation actually was.
