Leonard Kleinrock, UCLA faculty in Computer Science since 1964. He received his BA from CCNY and MA and PhD from the Massachusetts
Institute of Technology. Kleinrock ran the University of California, Los Angeles (UCLA) Network Measurement Center (NMC),
the first ARPANET node. The Kleinrock Papers include: McGraw-Hill Publishers correspondence; technical notes; Advanced Research
Projects Agency progress reports; publications materials; Interface Message processor logs; SPADE administrative notes; Miscellaneous
Network Notes; ARPANET Satellite System notes; Packet Radio Temp notes; and Networks Use Technical notes.
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.
