Lawrence Gilman Roberts (December 21, 1937 – December 26, 2018) was an American
As a program manager and later office director at the
Roberts later served as CEO of the commercial packet-switching network Telenet, the first public data network in North America.
Early life and education
Roberts, who was known as Larry, was born and raised in Westport, Connecticut.[7] He was the son of Elizabeth (Gilman) and Elliott John Roberts, both of whom had doctorates in chemistry. It is said that during his youth, he built a Tesla coil, assembled a television, and designed a telephone network built from transistors for his parents' Girl Scout camp.[8]
Roberts attended the
Career
MIT
After receiving his PhD, Roberts continued to work at the MIT
ARPA
In 1967, although at first reluctant, he was recruited by Robert Taylor in the ARPA Information Processing Techniques Office (IPTO) to become the program manager for the ARPANET. Roberts met Paul Baran in February 1967, but did not discuss networks.[11][12] He asked Frank Westervelt to explore the initial design questions for a network.[13] Roberts prepared a proposal that all host computers would connect to one another directly. Taylor and Wesley Clark disagreed with this design and Clark suggested the use of dedicated computers to create a message switching network, which were later called Interface Message Processors.[13][14]
At the Symposium on Operating System Principles that year, Roberts presented the plan based on Clark's message switching proposal.[15][16] There he met a member of Donald Davies's team (Roger Scantlebury) who presented their research on packet switching and suggested it for use in the ARPANET.[17][18] Roberts applied Davies's concepts of packet switching for the ARPANET, and sought input from Paul Baran.[19][20][21]
Roberts' plan for the ARPANET was the first wide area packet-switching network with distributed control, similar to Donald Davies' 1965 design.
In 1970, he proposed to
The Purdy Polynomial hash algorithm was developed for the ARPANET to protect passwords in 1971 at the request of Roberts.
Roberts approached AT&T in the early 1970s about taking over the ARPANET to offer a public packet switched service but they declined.[26]
Telenet
In 1973, Roberts left ARPA to join BBN's effort to commercialize the nascent packet-switching technology in the form of
Later career
In 1983 he joined
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.[32]
As of 2011[update], 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.[33]
Since September 2012, he was CEO of Netmax in Redwood City, California.[34]
Personal life
Roberts married and divorced four times. At the time of his death, his partner was physician Tedde Rinker.[7] Roberts died at his California home from a heart attack on December 26, 2018.[7][35]
