BBN Technologies

BBN has its roots in an initial partnership formed on 15 October 1948 between Leo Beranek and Richard Bolt, professors at the Massachusetts Institute of Technology. Bolt had won a commission to be an acoustic consultant for the new United Nations permanent headquarters to be built in New York City. Realizing the magnitude of the project at hand, Bolt had pulled in his MIT colleague Beranek for help and the partnership between the two was born. The firm, Bolt and Beranek, started out in two rented rooms on the MIT campus. Robert Newman joined the firm soon after in 1950, and the firm became Bolt Beranek Newman. Beranek remained the company's president and chief executive officer until 1967, and Bolt was chairman until 1976.

From 1957 to 1962, J. C. R. Licklider served as vice president of engineering psychology for BBN. Foreseeing the potential to obtain federal grants for basic computer research, Licklider convinced the BBN leadership to purchase a then state-of-the-art Royal McBee LGP-30 digital computer in 1958 for US$25,000. Within a year, Ken Olsen, president of the newly formed Digital Equipment Corporation (DEC), approached BBN to test the prototype of DEC's first computer, the PDP-1. Within one month, BBN completed its tests and recommendations of the PDP-1. BBN ultimately purchased the first PDP-1 for around US$150,000 and received the machine in November 1960.

After the PDP-1 arrived, BBN hired two of Licklider's friends from MIT, John McCarthy and Marvin Minsky, as consultants. McCarthy had been unsuccessful in convincing MIT engineers to build time-sharing systems for computers. He had more success at BBN though, working with Ed Fredkin and Sheldon Boilen in implementing one of the first timesharing systems, the BBN Time-Sharing System. In 1962, BBN would install one such time-shared information system at Massachusetts General Hospital where doctors and nurses could create and access patients' information at various nurses' stations connected to a central computer. BBN would soon begin more research about integrating computers and medicine, hiring Bob Taylor in 1965 and MIT Lincoln Laboratory computer systems engineer Frank Heart in 1966.

As BBN began focusing on computer technology, it gained a reputation as "the third university" in Cambridge alongside Harvard and MIT, and its offices expanded on a site near Fresh Pond in western Cambridge. By 1968, the company had over 600 employees. By the early 1970s, BBN bought a laundromat on Moulton Street and tore it down for a new, seven-story headquarters.

In 1980, the U.S. federal government charged BBN with contracts fraud, alleging that from 1972 to 1978, BBN altered time sheets to hide overcharging the government. That year, two top financial officers plea bargained for suspended sentences and US$20,000 fines, and the company paid a US$700,000 fine.

BBN's September 1994 celebration of the 25th anniversary of ARPANET generated much local and national news coverage from outlets including The Boston Globe, Newsweek, and National Public Radio. By that year, Heart retired from BBN after 28 years; his final position was president of the systems and technology division.

Computer technologies

BBN bought a number of computers in the late 1950s and early 1960s, notably the first production PDP-1 from Digital Equipment Corporation, on which it implemented the BBN Time-Sharing System (1962).

Ray Tomlinson of BBN is widely credited as having invented the first person-to-person network email in 1971 and the use of the @ sign in an email address.

BBN has had a distinguished career in natural-language understanding, ranging from speech recognition through machine translation. Most recently, BBN has expanded to the understanding of the causality of events and accurate forecasts for the Intelligence Advanced Research Projects Activity (IARPA).

BBN's education group, led by Wally Feurzeig, created the Logo programming language, conceived by BBN consultant Seymour Papert as a programming language that school-age children could learn. Other well-known BBN computer-related innovations include Interlisp programming language, the TENEX operating system, and the Colossal Cave Adventure game. BBN also is well known for its parallel computing systems, including the Pluribus, and Butterfly computers, which have been used for such tasks as warfare simulation for the U.S. Navy. BBN also developed the RS/1, RS/Explore, RS/Discover and the Cornerstone statistical software systems, and played a pioneering role in the development of today's semantic web, including participating in the DARPA Agent Markup Language project and chairing Web Ontology Language standardization.

In 1971, BBN's TELCOMP subsidiary was sold.

In the 1970s, BBN created Telenet, Inc., to run the first public packet-switched network.

In 1983, BBN Instruments was sold to Vibro-Meter Corp..

In 1989, BBN's acoustical consulting business was spun off into a new corporation, Acentech Incorporated, located across the street from BBN headquarters in Cambridge.
