Larry Landweber and David J. Farber Found CSNET (Computer Science Network), an Alternative to ARPANET

In 1979 Larry Landweber and David J. Farber  founded CSNET (the "Computer Science Network") with funding from the U.S. National Science Foundation. CSNET was a computer network linking academic Computer Science departments nationwide—an alternative to ARPANET, to which many Computer Science departments did not have the privilege of access. CSNET connected with ARPANET using TCP/IP, and ran TCP/IP over X.25, but also supported departments without sophisticated network connections, using automated dial-up mail exchange.
