John Mauchly and J. Presper Eckert unveil the much-anticipated ENIAC at the University of Pennsylvania. The ENIAC calculated 5,000 operations per second -- 1,000 times faster than its contemporaries. Impressive in size as well as strength, the machine occupied over 1,500 square feet of space, weighed 30 tons, and used 18,000 vacuum tubes.
