ENIAC is retired

On 2 October 1955 the ENIAC was struck by lightning. At 23.45 the same day, the power was finally shut off and the ENIAC stopped running.

It is widely believed that in the decade ENIAC was running, the machine performed more arithmetic than the entire human race had done prior to 1945.

Parts of the ENIAC are exhibited at the Smithsonian Institution and several other museums and universities.
