Lawrence G. Roberts (born December 21, 1937 in Connecticut) is an American scientist who received the Draper Prize in 2001 "for the development of the Internet",[4] and the Principe de Asturias Award in 2002.

As a program manager and office director at the Advanced Research Projects Agency, Roberts and his team created the ARPANET using packet switching techniques invented by British computer scientist Donald Davies.[5][6] The ARPANET was a predecessor to the modern Internet.

Early life and education[edit]

Lawrence (Larry) Roberts grew up in Westport, Connecticut as the son of Elliott and Elizabeth Roberts, who both had earned their doctorates in chemistry.[7] During his youth, he built a Tesla coil, assembled a television, and designed a telephone network built from transistors for his parent's Girl Scout camp.[7]

Roberts attended the Massachusetts Institute of Technology (MIT), where he received his bachelor's degree (1959), master's degree (1960), and Ph.D. (1963), all in electrical engineering.[7]


After receiving his PhD, Roberts continued to work at the MIT Lincoln Laboratory.[7] Having read the seminal 1961 paper of the "Intergalactic Computer Network" by J. C. R. Licklider, Roberts developed a research interest in time-sharing using computer networks.[8]

In 1967, he was recruited by Robert Taylor in the ARPA Information Processing Techniques Office (IPTO) to become the program manager for the ARPANET. Wesley A. Clark suggested the use of a dedicated computer, called the Interface Message Processor at each node of the network instead of centralized control. Shortly afterwards, at the 1967 ACM Symposium on Operating System Principles, Roberts met a member of Donald Davies' team (Roger Scantlebury) who presented their research on packet switching and suggested it for use in the ARPANET.[9] Roberts applied Davies' concepts of packet switching for the ARPANET,[10][11][12] and sought input from Paul Baran and Leonard Kleinrock. Subsequently, Roberts developed the plan for the ARPANET, the first wide area packet-switching network, and managed its implementation. ARPA issued a request for quotation (RFQ) to build the system, which was awarded to Bolt, Beranek and Newman (BBN). When Robert Taylor was sent to Vietnam in 1969 and then resigned, Roberts became director of the IPTO.

In 1973, Roberts left ARPA to commercialize the nascent packet-switching technology in the form of Telenet,[13] the first packet switch utility company, and served as its CEO from 1973 to 1980. In 1983 he joined DHL Corporation as President and CEO. He was CEO of NetExpress, an Asynchronous Transfer Mode (ATM) equipment company, from 1983 to 1993. Roberts was president of ATM Systems from 1993 to 1998. He was chairman and CTO of Caspian Networks, but left in early 2004; Caspian ceased operation in late 2006.[14]

As of 2011, Roberts was the founder and chairman of Anagran Inc. Anagran continues work in the same area as Caspian: IP flow management with improved quality of service for the Internet.[15]

Since September 2012, he was CEO of Netmax in Redwood City, California.

Awards and honors[edit]
