Biography/History
Leonard Kleinrock was born in New York City on June 13, 1934. He received a Bachelor of Electrical Engineering degree in 1957
from the City College of New York, and a master's degree and a doctorate (Ph.D.) in electrical engineering and computer science
from the Massachusetts Institute of Technology (MIT) in 1959 and 1963 respectively. Kleinrock developed a mathematical theory
of packet networks, the technology underpinning the Internet, while a graduate student at MIT in the period from 1960-1962.
Kleinrock has served as a Professor of Computer Science at the University of California Los Angeles (UCLA) since 1963. The
first host-to-host ARPANET connection occurred in the UCLA Network Measurement Center run by Kleinrock (3420 Boelter Hall
at UCLA) when his SDS Sigma 7 Host computer became the first node of the Internet in September 1969. From UCLA, Kleinrock
directed the transmission of the first message to pass over the Internet on October 29, 1969. Kleinrock served with programmer
Charley Kline as Chairman of the Computer Science department at UCLA from 1991-1995 and is a Distinguished Professor of Computer
Science at UCLA. During his tenure at UCLA, Kleinrock supervised the research for 48 Ph.D. students and numerous M.S. students
who formed a core of advanced networking experts. Kleinrock has published over 250 papers and authored six books on a wide
array of subjects, including packet switching networks, packet radio networks, local area networks, broadband networks, gigabit
networks, nomadic computing, intelligent software agents, performance evaluation, and peer-to-peer networks. Kleinrock received
numerous awards including the prestigious National Medal of Science in 2008 for his contributions to the mathematical theory
of modern data networks and for the functional specification of packet switching. In 2012, Kleinrock was inducted into the
Internet Hall of Fame by the Internet Society.
Scope and Content
Leonard Kleinrock's papers include: correspondence for publication of his book,
Communication nets: Stochastic message flow and delay. (McGraw-Hill, 1964); technical notes from his design work at Digital Equipment Corporation (DEC); and materials from the
Network Measurement Center (NMC) which discuss the early development of the Internet in the United States during the 1960s
and 1970s. Materials from the NMC consist of notes and papers from the first ARPANET node at UCLA. The papers include Interface
Message Processor Logs documenting the first message on the ARPANET and progress reports to ARPA. The notes detail the technical
evolution of the ARPANET Satellite System (ASS) and the ALOHA system including Request for Comments (RFC) and a Bolt Beranek
and Newman Quarterly Technical Report. There are also Administrative notes from the SPADE Group, responsible for the Sigma
7 system software and programming support for the ARPA project, consisting of Agenda, meeting notes, and bug lists including
NUTS notes referring to the TENEX program. Finally there are notes detailing Packet Radio Communication and its application
for distribution of data consisting of meeting notes, academic papers, and protocol notes. Arrangement is by note number first
and then chronologically providing a technical progression for the history of the ARPANET.
Organization and Arrangement
The collection is arranged into the following series:
- 1. McGraw-Hill Publishers Correspondence
- 2. Technical Notes
- 3. Progress Reports to the Advanced Research Projects Agency
- 4. Publications
- 5. Interface Message Processor Logs
- 6. SPADE Administrative Notes
- 7. Miscellaneous Network Notes
- 8. ARPANET System Satellite Notes and Request for Comments
- 9. Packet Radio Temp Notes
- 10. Networks Use Technical (NUTS) Notes
Manuals and documents are ordered chronologically within series. Notes are ordered by note number first and then chronologically
to reflect the original arrangement which provides a progression for the history of the ARPANET.
