In 1965, L. G. Roberts (Lawrence G.) successfully implemented the first computer-to-computer packet link between MIT and Systems
Development Corporation (SDC). In 1966, Roberts became the chief scientist and in 1967 the director of the Information Processing
Techniques Office (IPTO) of the Advanced Research Projects Agency (ARPA), later renamed the Defense Advanced Research Projects
Agency (DARPA) of the United States Department of Defense (DoD). As director, Roberts was responsible for designing and managing
the implementation of the Advanced Research Projects Agency Network (ARPANET) computer communications network, a research
packet switching computer communications network that was the precursor to the internet.
The collection contains the professional and research files of L. G. Roberts dating from 1962 to 2009 and includes publications;
notes written by Roberts concerning the development of the Advanced Research Projects Agency Network (ARPANET); notes on the
internet and on networked computing more broadly; professional correspondence.
