61 years ago today, on June 14th 1951 the very first electronic computer produced in series (and in the United States), the UNIVAC I (Universal Automatic Computer) was delivered to the US States Census Bureau at the price of $1.6 Mio. It was designed principally by J. Presper Eckert and John Mauchly, the inventors of the first general-purpose electronic computer, the ENIAC.
