Samuel N. Alexander

Alexander assisted Margaret R. Fox in developing a series of college computer courses beginning in 1966.

In this case, they were waiting for a computer by UNIVAC (Alexander was also involved in its design), whose delivery had been delayed.

Alexander's chief architect was Ralph J. Slutz (1917-2005) who previously worked with John von Neumann to build a computer at the Institute for Advanced Study.

The computer operated for 14 years and was originally intended for training purposes within government agencies, but some of the earliest assemblers and compilers were built for it.

Alexander also initiated the prototype DYSEAC at the NBS, a successor to the SEAC, which was built for the US Signal Corps.
