Bob Kahn

Robert Elliot Kahn was born on December 23, 1938, in Brooklyn, New York. He recalled that the family first lived on Ocean Parkway and later rented a house on 19th Street in the Flatbush part of Brooklyn; he described his childhood as happy and fairly normal, with street ball and bicycle riding.⁠[1][2][3]

He recalled that his father was a high school administrator throughout his childhood: he began teaching accounting, the subject of his college degree, at Tilden High School in Brooklyn during the Depression, rose to dean of students and other administrative posts, and gave business advice on weekends. His father later teamed up with William Kellman, who owned about a dozen nursing homes in the New York area, to design a paper-forms system for managing nursing homes; the company, called Macrobiotics (a name that, Kahn said, did not mean anything back then), before long served nursing homes in all 48 states, and his father ran it until he died at about 89 or 90. In 2006 Kahn ran the company himself as a one-person operation. He called his father “the pillar of the family” and the person he most looked up to.⁠[3]

He recalled that his mother was bright and socially minded, devoted to education and to helping others; as a young woman she had to work to bring in family income and never went to college, and in later life she went back to college and earned degrees—“a 70-year-old woman getting college degrees,” he said. She had probably had rheumatic fever as a child; in her thirties she had the first of what he put at eight heart attacks in all, and she was bedridden for long stretches; she had closed-heart surgery in 1953 and open-heart valve surgery at New York Hospital in 1982, and after a further operation in 1994 she never left the hospital, dying that year at 80.⁠[3]

He has one sister, Diana, about two years younger, who was valedictorian of the high school he also graduated from; she graduated first at Queens College, earned a Ph.D. in mathematics at the University of Chicago and later became more interested in health-related issues. Kahn said that Herman Kahn of the RAND CorporationRAND CorporationThe RAND Corporation is an American nonprofit research organization headquartered in Santa Monica, California. It grew out of Project RAND, set up by the U.S. Army Air Forces in 1946 under contract with the Douglas Aircraft Company, became an independent nonprofit in 1948 and conducts research on national security, health, education and social policy.Open the full entry was a relative on his father’s side, Herman Kahn’s father having been, he thought, a brother of Kahn’s paternal grandfather, and that Moe Berg, a lawyer who had been a catcher for the Brooklyn DodgersLos Angeles DodgersThe Los Angeles Dodgers are a professional baseball club in Los Angeles, playing in Major League Baseball’s National League at Dodger Stadium.Open the full entry and who, he said, was recruited for translation work in wartime, was a relative on his mother’s side whom he never met.⁠[3]

He began high school at Madison in Brooklyn. In 1952 or 1953 the family moved to Flushing, where he spent his junior and senior years of high school and lived until graduate school. He joined the high school golf team, starting as the fifth man, and said he ranked “probably eighth or something” in his class. He graduated from high school in 1955.⁠[3][4]

He entered college at about 16, spending two years at Queens College before transferring to the engineering program of the City College of New York; he said the choice was driven by family finances and the need to stay close to home, and he described City College as practical and well taught, with a commuter culture. The professor who most influenced him was Egon Brenner, who in his senior year set up an advanced-studies class in which Kahn was the only student. He finished his coursework in December 1959 and graduated in January 1960 with a Bachelor of Electrical Engineering (B.E.E.).⁠[3][5]

After graduating he wanted work experience before graduate school and joined the headquarters of Bell Telephone Laboratories at 463 West Street in Manhattan, working in an operations research group and writing Monte Carlo simulations on an IBMIBMIBM (International Business Machines Corporation) is an American information technology company, renamed in 1924 from the Computing-Tabulating-Recording Company (C-T-R).Open the full entry 704 to evaluate switching components; the authors’ notes of the 1974 paper instead place him at Bell Telephone Laboratories in Murray Hill, New JerseyNew JerseyNew Jersey is a state in the eastern United States on the Atlantic Ocean, bordered by New York State, Delaware, and Pennsylvania, with the Hudson River forming its northeastern boundary and the Delaware River its western boundary; its capital is Trenton and its largest city is Newark. One of the original 13 colonies, it became the third state to ratify the U.S. Constitution on December 18, 1787, and its population in the 2020 census (April 1, 2020) was 9,288,994.Open the full entry, engaged in traffic and communication studies. While at Bell Labs he applied for a National Science Foundation (NSF) graduate fellowship.⁠[3][2]

Sources differ on his time at Bell Labs: the authors’ notes of the 1974 paper and the Japan Prize laureate profile give 1960–1962; IEEE Spectrum’s 2024 profile states that he stayed at Bell Labs for about nine months before taking up a graduate fellowship and returned there in the following summers; the Association for Computing Machinery’s Turing Award biography lists his post on the technical staff of AT&TAT&TAT&T (AT&T Inc.) is a telecommunications company headquartered in Dallas, Texas. Its predecessor was SBC Communications, a regional holding company created in the 1984 breakup of the Bell System; SBC merged with the original AT&T Corp. in 2005 and adopted its name, and it has since operated a nationwide wireless network and fiber broadband, at one time also owning DIRECTV and WarnerMedia.Open the full entry Bell Labs as 1964–1966.⁠[2][6][4][1]

He went to Princeton UniversityPrinceton UniversityPrinceton University is a private university and Ivy League member in Princeton, New Jersey. Chartered on October 22, 1746 as the College of New Jersey, it moved to Princeton in 1756 and adopted its present name in 1896. Undergraduate education leads to A.B. and B.S.E. degrees and emphasizes small-group discussion, independent research and residential college life. Graduate education spans the humanities, social sciences, natural sciences and engineering. As of October 2026, Christopher L. Eisgruber was president. Its 2026–27 operating budget was $3.407 billion, including $342 million for undergraduate aid.Open the full entry on the NSF fellowship, choosing it, he said, partly because it was close to home and for its social atmosphere. His adviser was John Thomas. He received an M.A. in electrical engineering in 1962 (an M.S. in the Japan Prize profile) and in 1964 a Ph.D. in electrical engineering with the thesis “Some problems in the sampling and modulation of signals”; IEEE Spectrum notes that his doctoral thesis involved signal processing.⁠[3][1][6][4]

He applied late in the cycle to Stanford UniversityStanford UniversityStanford University is a research university in California founded by Leland and Jane Stanford in 1885 and opened in 1891.Open the full entry and the Massachusetts Institute of TechnologyMassachusetts Institute of TechnologyThe Massachusetts Institute of Technology (MIT) is a private research university in Cambridge, Massachusetts, United States. It received its charter from Massachusetts in 1861, admitted its first students in 1865 and moved from Boston to its present campus in 1916. As of October 2025 it had 11,816 students, and it counts 106 Nobel laureates among members of its community.Open the full entry (MIT), and Peter Elias, chair of MIT’s electrical engineering department, invited him to interview and give a seminar. From 1964 to 1966 he was a Ford Postdoctoral Fellow and Assistant Professor of Electrical Engineering at MIT, teaching information theory and courses in circuits and communications theory; asked whether he was one of the youngest members of the faculty, he said, “Probably the youngest.” Jack Wozencraft advised him to take time to gain practical experience.⁠[3][2]

The Association for Computing Machinery’s Turing Award biography instead states that he joined MIT’s electrical engineering department as an assistant professor in 1966 and arranged a leave in 1967 to work at Bolt Beranek and Newman.⁠[1]

He considered MIT Lincoln Laboratory and Bolt Beranek and Newman (BBN) and, with Lincoln Laboratory under a hiring freeze, chose BBN. He recalled joining BBN in October 1966 and staying until October 1972; the authors’ notes of the 1974 paper describe him as a senior scientist at BBN from 1966 to 1972, working on computer communications network design and distributed computation. Jerry Elkind of BBN gave him freedom to explore, and he began working on computer networking there; he said, “I wasn’t hired to do anything in particular.” He recalled being advised that networking “would be a bad thing to work on,” and pursued it anyway.⁠[3][2][4]

In 1968 Lawrence Roberts of ARPA issued a request for proposals for an experimental large-scale network. Kahn recalled meeting Bob Taylor around 1967 and sending his networking memos with a letter to Lawrence Roberts, whom he did not then know. Kahn wrote the technical part of BBN’s proposal, with Severo Ornstein responsible for the hardware; after BBN won the ARPANET contract he joined the team led by Frank Heart and led the system design of the ARPANET, the first packet-switched network. He recalled, “It never dawned on me that I’d actually get involved in building it.”⁠[1][3][7][4]

The first four ARPANET nodes were built to a nine-month delivery target. In 1969 Kahn went to the University of California, Los Angeles (UCLA) to help test the early ARPANET and there met Vint Cerf, who was the UCLA point person for the testing; in his 2006 oral history Kahn also said that this node testing was how he first really got to meet Cerf. He also built a simulation and demonstrated a network lockup problem that management had dismissed; the fix took about a year of software rework.⁠[1][3]

In October 1972 Kahn led the first public demonstration of the ARPANET at the International Computer Communication Conference (ICCC), held at the Washington Hilton in Washington, D.C. The Queen Elizabeth Prize for Engineering website states that the demonstration connected several dozen computers and showed that packet switching was viable.⁠[1][3][8][9]

He recalled that BBN then almost immediately decided to go down the commercial path, which led to Telenet; he and Steve Levy planned the creation of the company, but by his own choice he had no role in Telenet.⁠[3]

At the end of October 1972 he left BBN and joined DARPA’s Information Processing Techniques Office (IPTO) as a program manager; IEEE Spectrum writes that he officially left BBN the day after the ARPANET demonstration concluded to join DARPA. He recalled that DARPA had recruited him to run an automated-manufacturing effort—“They hired me to run a hundred-million-dollar program on automated manufacturing”—but soon after he arrived Congress cut off its funding. He then worked on packet radio, packet satellite and packetized voice, and was the chief architect of the packet radio network; he credits Lawrence Roberts with the packet satellite concept.⁠[3][1][4]

In spring 1973 Kahn proposed developing a system for interconnecting networks, and a seminar in June 1973 brought in outside networking experts. He conceived open-architecture networking and originated DARPA’s Internet Program. DARPA’s TCP/IP page states that Kahn asked Vint Cerf of Stanford University to help develop new protocols for moving data packets over the ARPANET, work that produced the Transmission Control Protocol (TCP) and the Internet Protocol (IP). IEEE Spectrum’s January 2024 award story states that in March 1973 he recruited Cerf, then a Stanford professor, to help develop the open-architecture idea, and that the two designed TCP and IP over about six months. Their design was presented at the International Network Working Group (INWG) meeting in Sussex, England, in September 1973.⁠[1][7][10][3][11]

Cerf recalled that Kahn proposed rules letting separate networks remain autonomous while interacting: “He called it internetworking.” Kahn said his electrical-engineering background complemented Cerf’s: “Vint, as a computer scientist, thought of things in terms of bits and computer programs.”⁠[4]

In May 1974 the paper “A Protocol for Packet Network Intercommunication” by Vint Cerf and Kahn was published in IEEE Transactions on Communications, vol. COM-22, no. 5. It presents a protocol that lets resources in different packet-switching networks be shared, discusses the differences among networks in packet size, transmission failures, sequencing, flow control and end-to-end error checking, and the creation and termination of logical process-to-process connections, and lists open problems such as internetwork routing, accounting and timeouts; the acknowledgments thank R. Metcalfe, R. Scantlebury, D. Walden, H. Zimmerman, D. Davies, L. Pouzin and S. Crocker. The Association for Computing Machinery’s Turing Award biography states that the paper outlined the architecture of the Internet, including TCP and a hierarchical addressing system.⁠[2][3][1]

The authors’ notes of the paper list him as a member of Tau Beta Pi, Sigma Xi, Eta Kappa Nu, the Institute of Mathematical Statistics and the Mathematical Association of America, and as a 1972 National Lecturer of the Association for Computing Machinery. Sigma Xi’s interview states that he joined Sigma Xi in 1966 and is a life member.⁠[2][12]

From 1972 to 1979 he served at IPTO successively as program manager, chief scientist and deputy director. He recalled that when Vint Cerf joined ARPA in 1976 he was, he thought, chief scientist and probably deputy director; after Cerf left for MCI in 1982, Kahn ran the Internet program again for about a year.⁠[6][3]

In 1977 Kahn and Cerf oversaw the experimental connection of the ARPANET, the packet radio network PRNET and the packet satellite network SATNET, which the Association for Computing Machinery’s Turing Award biography calls the first incarnation of the Internet.⁠[1]

In 1978 Cerf, Jon Postel and Danny Cohen split TCP into TCP and IP, which Cerf described in a 1980 article.⁠[1]

IEEE Spectrum records that Kahn initially assigned the network part of IP addresses himself, keeping the records on a single card in his shirt pocket; when the card began to fill up in the late 1970s he decided to hand the task to others, and it passed to Jon Postel and later to IANA.⁠[4]

From 1979 to 1985 Kahn was Director of IPTO (IEEE Spectrum’s April 2024 profile gives 1979 to late 1985; its January 2024 award story states that he became director in 1983). Projects he started at DARPA included network security, digital speech, packet radio and, in 1983, the Strategic Computing Initiative; he said the program was structured with substantial input from Bob Cooper and aimed to make DARPA’s computing technology available to industry for defense use.⁠[1][6][4][3][11]

He recalled that research funding dropped precipitously between roughly 1973–1974 and 1978–1979, and that he created a VLSI design program in response; it moved to the Information Sciences Institute (ISI) of the University of Southern CaliforniaUniversity of Southern CaliforniaThe University of Southern California (USC) is a private research university in Los Angeles, California, planned by a group led by Judge Robert Maclay Widney and opened to students in 1880.Open the full entry under Keith Uncapher, with Danny Cohen as program manager, and the name MOSIS, including its “I,” came from Kahn. Sigma Xi’s interview states that at DARPA he helped fund MOSIS, a chip-fabrication service now managed by the University of Southern California.⁠[3][12]

In 1983 the protocols on the ARPANET were converted from NCP to TCP/IP, a changeover Kahn helped guide. In his oral history he said that the plan had been worked out years earlier, written down by Jon Postel and announced by DARPA a year or two ahead; that managing the transition fell to him; that it did not go at all as he had expected, and that the two protocols ran in parallel for at least six months.⁠[1][3]

In September 1985, after 13 years at DARPA, Kahn left and stayed on as a consultant, helping Saul Amarel take over the office. He recalled that he left at the top of the defense build-out, with no more new money going into the Department of DefenseU.S. Department of DefenseThe U.S. Department of Defense is an executive department of the United States federal government, formed in 1949 from the National Military Establishment created in 1947 and headquartered at the Pentagon. The department’s website describes it as America’s oldest and largest government agency.Open the full entry, and that this, together with a growing number of classified “black programs” and earmarks, meant he “couldn’t do anything new.”⁠[3]

In the mid-1980s he coined the term “National Information Infrastructure.”⁠[7][13]

On January 29, 1986, Kahn filed the incorporation papers of the Corporation for National Research Initiatives (CNRI), a date he remembers because, he said, they heard the announcement of the Challenger explosion as they were going through the papers; he recalled that it began with one employee, himself, and that Vint Cerf became employee number two in June 1986. CNRI is a not-for-profit organization devoted to research and development for the national information infrastructure and to collaboration among government agencies, universities and companies. CNRI, the Internet Hall of Fame and the DONA Foundation give 1986 as the founding year; IEEE Spectrum’s April 2024 profile states that he left DARPA in 1985 to form the nonprofit (its January 2024 award story says he left DARPA in 1986 to found CNRI), and BritannicaEncyclopædia BritannicaEncyclopædia Britannica is a general English-language encyclopedia first published in Edinburgh, Scotland, in 1768; the name also refers to its publisher, Chicago-based Encyclopædia Britannica, Inc.

He recalled that early supporters included IBM, Digital Equipment, Xerox, MCI, Bellcore and Bell Atlantic. IEEE Spectrum records that the commitments of industry backers, among them Bell Atlantic, Bellcore, Digital Equipment Corp., IBM, MCI, NYNEX and Xerox, totaled over a million dollars a year for several years, and that CNRI intended to make its research results open to all.⁠[3][4]

In 1992 Kahn and Vint Cerf founded the Internet Society.⁠[11]

In 1997 Kahn and Vint Cerf received the National Medal of Technology; that year he also received the IEEE Alexander Graham Bell Medal (IEEE Spectrum states that he shared it with Cerf).⁠[6][7][11]

In 1998 Princeton University gave him an honorary degree, presented by its president, Harold Shapiro.⁠[3]

In May 2001 Kahn and Patrice A. Lyons of the Law Offices of Patrice Lyons, Chartered, published “Representing Value as Digital Objects: A Discussion of Transferability and Anonymity” in D-Lib Magazine, vol. 7, no. 5. The article discusses how “value” such as deeds of trust, mortgages, bills of lading and digital cash can be represented as digital objects on a network without a physical artifact, introduces “transferable records” structured as digital objects and relates them to the UETA and the ESIGN Act in U.S.United StatesThe United States is a federal country in North America made up of 50 states, the District of Columbia as the seat of government, and territories such as Puerto Rico and Guam; its capital is Washington, D.C.

The article proposes the Handle System as the identifier and resolution system and acknowledges that the framework is incomplete.⁠[16]

Kahn and Vint Cerf shared the 2004 A. M. Turing Award, cited “for pioneering work on internetworking” and “for inspired leadership in networking.”⁠[1]

On November 9, 2005, George W. BushGeorge W. BushGeorge W. Bush (born 1946) is an American politician and Republican who worked in the energy business and was a part owner of the Texas Rangers baseball team before becoming the 46th governor of Texas in 1995 and serving as the 43rd president of the United States from 2001 to 2009.Open the full entry presented the Presidential Medal of Freedom to Kahn and Vint Cerf, among others. In his remarks Bush said that Robert Kahn, an engineer, and Vinton Cerf, a computer scientist, had thirty-two years earlier worked out how to transmit data between separate computer networks, a process Kahn called “internetting,” and that their common digital language for computers across networks had prepared the way for a technological revolution. Other recipients that day included Alan GreenspanAlan GreenspanAlan Greenspan (1926–2026) was an American economist who served as the 13th Chairman of the Board of Governors of the Federal Reserve System from 1987 to 2006, after earlier serving as chairman of the President’s Council of Economic Advisers.Open the full entry, Muhammad Ali, Aretha Franklin and Jack Nicklaus. CNRI’s biography of Kahn lists the medal under 2004.⁠[17][13]

On September 30, 2006, Vint Cerf interviewed Kahn in McLean, Virginia, for the Computer History Museum’s oral history program; the conversation covers, in order, his family and childhood, his schooling, Bell Labs, Princeton University and MIT, BBN and the ARPANET, packet radio and internetworking at DARPA, his departure from DARPA, the founding of CNRI and its later work. Near the end he advised, “leave a little room for serendipity,” and described the Internet as “a dynamic organic system.”⁠[3]

In January 2008 Kahn and Vint Cerf, then a vice president of Google, were named recipients of the 2008 Japan Prize in the field of “Information Communication Theory and Technology” for creating a network architecture and communication protocol for the Internet; the prize carries 50 million yen, about $470,000.⁠[18]

IEEE Spectrum records that in 2014 CNRI handed its prefix-registry responsibility to a newly formed international body, the DONA Foundation in Geneva. The DONA Foundation is a non-profit organization established in Geneva, Switzerland; its website states that CNRI designed the Digital Object Architecture and founded the DONA Foundation.⁠[4][15]

Kahn received the 2024 IEEE Medal of Honor “for pioneering technical and leadership contributions in packet communication technologies and foundations of the Internet”; the annual award is sponsored by the IEEE Foundation. Princeton University’s engineering school noted in its news story of December 8, 2023, that he earned his Ph.D. there in 1964 and had served as an adviser to its Department of Computer Science.⁠[11][19]

The medal was presented to him at the IEEE Honors Ceremony during the IEEE Vision, Innovation, and Challenges Summit, held in Boston on May 2 and 3, 2024; the ceremony, the highlight of the summit’s second evening, concluded with the presentation, and he received a standing ovation. He said, “This is the honor of my career.”⁠[20]

On May 7, 2024, TechCrunchTechCrunchTechCrunch is an American technology news outlet founded in 2005 by Michael Arrington and Keith Teare and headquartered in San Francisco; it mainly covers technology companies, startups, and venture capital, and hosts events such as TechCrunch Disrupt. Its ownership passed successively through AOL, Verizon, and Yahoo, and in 2025 Regent announced its acquisition.Open the full entry published Devin Coldewey’s interview with Kahn, conducted on the occasion of his being awarded the IEEE Medal of Honor that week. Kahn likened cryptocurrency to a one-dollar bill without the paper, being able to work with the value of money on the net, and said this was the same idea behind his digital-object work; he said he had written a paper on representing value in digital objects which he believes was the first to discuss the equivalent of cryptocurrency. He traced the linking of blocks to space communications, where with a delayed signal it is useful to link blocks in transit: “that’s what blockchains are about.”⁠[21]

In the interview he also said that the early Internet was built by a very willing set of collaborators from the research community who principally knew one another, whereas as the network grew “you get a little bit of everything in society”; he said that when CERN’s leadership approached him about a consortium (later set up at the Massachusetts Institute of Technology) he raised questions of misinformation and disinformation, and he was disappointed that “approaches that could have made a difference were not adopted.” He said the United States had not maintained its leadership in semiconductor manufacturing, applauded current efforts to fix that and said that developing a workforce to staff the plants would be a big part of the problem: “we were there before, we can get there again.”⁠[21]

As of November 2026 the CNRI website lists Kahn as Chairman, CEO and President; the DONA Foundation website lists him as Director and Chair Emeritus, while CNRI’s biography of Kahn still describes him as Chair of the DONA Foundation.⁠[14][15][13]

Kahn’s wife, Patrice Ann Lyons, is a copyright and communications lawyer and his collaborator on much of his digital-object work; she handled licensing questions on Python for CNRI. He counted meeting Patrice and getting involved with her among the most important moments of his life, said she had shown him some of the more interesting aspects of law, and credited her with his realization that the problem “wasn’t so much technical as it was social, legal, and political”; he advised others to “marry a good woman or the opposite.”⁠[4][3]

IEEE Spectrum’s 2024 fact box records that his first job was as a runner for a Wall Street brokerage firm and his first electronics job was at Bell Telephone Laboratories in New York City; his leisure activities are skiing, whitewater canoeing, tennis, golf and cooking—he learned to cook Chinese food from Franklin Kuo, co-developer of ALOHAnet at the University of Hawaii; he likes opera and operatic musicals; his favorite films are The Day the Earth Stood Still (1951) and Casablanca (1942); his favorite books are Barbara W. Tuchman’s The March of Folly: From Troy to Vietnam (1984) and Samuel Eliot Morison’s The Two-Ocean War (1963); his heroes are his parents, his wife, Egon Brenner, Irwin Jacobs and Jack Wozencraft; and his organizations include the IEEE, the Association for Computing Machinery, the U.S. National Academies of Sciences and Engineering, and the Marconi Society.⁠[4]

At CNRI Kahn developed the Digital Object Architecture, which underlies the Digital Object Identifier (DOI) system. IEEE Spectrum explains that a digital object is a sequence of bits, or a set of such sequences, having a unique identifier and that the architecture combines digital objects, distributed repositories, metadata registries and a decentralized identifier-resolution system. In the Sigma Xi interview he explained that each digital object has a persistent identifier so that it can be retrieved whatever technology comes later. He said the Handle System had been on the Internet “since 1994” and described the International DOI Foundation and publishers’ use of the identifiers.⁠[7][5][4][12][3]

With Robert Wilensky of the University of California, BerkeleyUniversity of California, BerkeleyThe University of California, Berkeley (UC Berkeley) is a campus of the University of California system; the University of California was founded in 1868 through a merger of two institutions and moved to Berkeley, California, in 1873.Open the full entry, he wrote “A Framework for Distributed Digital Object Services,” published in the International Journal on Digital Libraries in 2006. In 2003 he received the Digital ID World award for the Digital Object Architecture. He holds several patents, two of them related to the Digital Object Architecture and two on remote pointing devices. In his 2024 TechCrunch interview he said that he found it a shame that digital objects are often assumed to mean only copyrighted material; in his view they can represent anything in digital form, so “you’ve potentially got everything interacting with everything.”⁠[4][13][21]

Kahn co-invented Knowbot programs, mobile software agents. He recalled that CNRI’s browser work for the National Library of Medicine involved generating Knowbots behind the scenes. TechCrunch’s 2024 article describes Knowbots as “knowledge robots” that could be sent out to book flights, check email or monitor news; the project was shelved amid security concerns around the time of the Morris worm in the late 1980s, and Kahn said it was put “on the back burner.”⁠[7][3][21]

IEEE Spectrum records that CNRI obtained U.S. government funding to create a secretariat for the Internet Activities Board, which eventually led to the establishment of the Internet Engineering Task Force (IETF), and ran the secretariat for about 18 years. Kahn recalled that it operated under a cooperative agreement with the National Science Foundation through 1997, with Phil Gross and Steve Coya leading the IETF work for CNRI; in 1997 the secretariat moved to a CNRI subsidiary, which was sold to NeuStar in December 2005.⁠[3][4]

CNRI built five gigabit testbeds, a program Kahn said “put high speed networking on the map”; IEEE Spectrum writes that he obtained funding from the National Science Foundation to build the testbeds and that DARPA funded a CNRI digital library effort. Kahn credited Guido van RossumGuido van RossumGuido van Rossum is a programmer who grew up in the Netherlands and the creator of the Python programming language, which he began writing in 1989 and led for decades as its “BDFL” (Benevolent Dictator For Life) until stepping down in 2018; he worked at CWI, CNRI, Google, Dropbox and Microsoft.Open the full entry with creating Python and said CNRI helped the language grow from work begun at CWI. The CNRI website lists its work as including design and fabrication support for the MEMS and Nanotechnology Exchange, research in digital libraries and networked information technologies, and testbeds with industrial, academic and federal partners.⁠[3][14][4]

Other honors listed by the Japan Prize profile and the CNRI website include the Association for Computing Machinery’s President’s Award (1985), the AFIPS Harry Goode Memorial Award (1986), the Computing Research Association Distinguished Service Award (1990), the Association for Computing Machinery’s Software System Award with Vint Cerf (1991), the IEEE Koji Kobayashi Computers and Communications Award (1992), the Association for Computing Machinery’s SIGCOMM Award (1993), the Marconi Award (1994), the Charles Stark Draper Prize with Cerf, Lawrence Roberts and Leonard Kleinrock (2001), the Prince of Asturias Award for Technical and Scientific Research with Cerf, Kleinrock, Roberts and Tim Berners-Lee (2002), the C&C Prize, received in Tokyo, and the Townsend Harris Medal of the City College of New York (2005), induction into the National Inventors Hall of Fame (May 2006), the Harold Pender Award of the University of PennsylvaniaUniversity of PennsylvaniaThe University of Pennsylvania, commonly called Penn, is a private research university and Ivy League member in Philadelphia. It traces its origins to a 1740 charity-school project; Benjamin Franklin proposed his academy in 1749, classes began in 1751, and a 1791 merger established the institution under its present name. Penn has 12 schools, with undergraduate education concentrated in arts and sciences, engineering, nursing and Wharton.
