Eckert-Mauchly Computer Corporation

Before 1946 a computer was a one-off, built for a laboratory or an ordnance office and paid for by whoever wanted that particular set of calculations done. Eckert and Mauchly left the Moore School rather than sign away patent rights, and the firm they set up in Philadelphia made the machine itself the product, sold to customers with no intention of building one. BINAC, delivered to Northrop in 1949, ran two processors in step so that each checked the other, treating reliability as a design requirement rather than a research curiosity, because a buyer expects the thing to work on a Tuesday. UNIVAC I, accepted by the Census Bureau in March 1951, put data on magnetic tape instead of punched cards and was built as a series; forty-six were eventually sold at over a million dollars each. Two consequences reached artificial intelligence. Programming became separable from the hardware: Mauchly proposed Short Code in 1949, it ran on UNIVAC I the following year as the first high-level notation actually used on an electronic computer, and the same group, Grace Hopper among them, produced the A-0 compiler system in 1952. Second, the public acquired an image. When UNIVAC called the 1952 presidential landslide from a sliver of early returns on live television, millions of people watched a machine draw an inference, and electronic brain entered ordinary speech well ahead of anything the field could actually deliver.
