Stephen L. Squires *73

Stephen Squires, a noted computer scientist for national security, died April 26, 2019, at the age of 71.

Squires graduated from Drexel University in 1970 with a bachelor’s degree in electrical engineering. He then earned a master’s degree in electrical engineering from Princeton in 1973. Later, he received a Ph.D. in computer science from Harvard in 1998.

He worked in government for almost 30 years. Starting at the National Security Agency, he then was at the Defense Advanced Research Projects Agency (DARPA), where he was a research program manager, office director, and finally special assistant for IT. From 2000 to 2006, he was chief science officer at Hewlett-Packard, after which he founded Kelvin 1687, a consultancy focused on the future of IT.

While at DARPA, he led efforts advancing modern parallel computer architecture and associated Unix-based systems software, with lasting influences on the design of modern large-scale computing. In the late 1980s he helped advance a research partnership among federal agencies that continues as nitrd.gov, the Networking and Information Technology Research and Development Program.

Squires is survived by his wife, Ann B. Marmor-Squires *72; and two daughters, Gayle and Robyn.
