Abstract :
The Charles Babbage Institute has conducted a year-long lecture series on the theme of "Minnesota\´s Hidden History in Computing." Historically, only people in the computer world know the story of Minnesota\´s pioneering computing work. Throughout the 1950s and 1960s, and even into the 1980s, Minnesota was a leading region in the US for computing. Companies active there - Engineering Research Associates (ERA), Sperry-Rand Univac, Control Data, Cray, Honeywell, IBM Rochester, and others - were among the leaders in the industry, especially before the blossoming of the Route 128 minicomputer industry outside Boston and the microcomputer, software, and networking industries of Silicon Valley.
