20 Facts About Leonard Kleinrock

Leonard Kleinrock was born on June 13,1934 and is an American computer scientist and Internet pioneer.

Leonard Kleinrock is Distinguished Professor Emeritus of Computer Science at UCLA's Henry Samueli School of Engineering and Applied Science.

Leonard Kleinrock supervised graduate students who worked on the communication protocols for the ARPANET including students whose later work on internetworking and the Internet protocol suite led to the networking technology employed in the Internet.

Leonard Kleinrock was born in New York City on June 13,1934, to a Jewish family, and graduated from the noted Bronx High School of Science in 1951.

Leonard Kleinrock analyzed delays in Plan 55-A, a message switching system operated by Western Union for processing telegrams.

Leonard Kleinrock's thesis went on to apply probability theory to model queueing delays in a generalized communication network.

Leonard Kleinrock was awarded a contract in 1968 to establish a Network Measurement Center to measure and model the performance of the network.

Leonard Kleinrock used the ARPANET for instant messaging from the US to Larry Roberts in England in 1973, employing the network for a modern every-day use.

Leonard Kleinrock published hundreds of research papers, which ultimately launched a new field of research on the theory and application of queueing theory to computer networks.

Leonard Kleinrock disseminated his research and that of his students to wider audiences for academic and commercial use, and organized hundreds of commercial seminars presented by experts and pioneers in the US and internationally.

Many graduate students that Leonard Kleinrock supported based their careers on expertise they acquired while working on the ARPANET with him, including several whose later work on internetworking and the Internet protocol suite led to the networking technology employed in the Internet.

Leonard Kleinrock's work published in the mid-1970s on the performance of the ARPANET, which was discussed at the International Network Working Group, underpinned the development of the Transmission Control Protocol of the Internet protocol suite.

In 1988, Leonard Kleinrock was the chairman of a group that presented the report Toward a National Research Network to the US Congress, concluding that "There is a clear and urgent need for a national research network".

However, Leonard Kleinrock's claims that his work in the early 1960s originated the concept of packet switching and that his work was a source of the packet switching concepts used in the ARPANET are disputed by other Internet pioneers, including Robert Taylor, Paul Baran, and Donald Davies.

Leonard Kleinrock made several important contributions to the field of computer science, in particular to the mathematical foundations of data communication in computer networking.

Leonard Kleinrock was elected as a member into the National Academy of Engineering.

In 2012, Leonard Kleinrock was inducted into the Internet Hall of Fame by the Internet Society.

Leonard Kleinrock was elected to the 2002 class of Fellows of the Institute for Operations Research and the Management Sciences.

In September 2014, Leonard Kleinrock was awarded the ACM SIGMOBILE Outstanding Contribution Award at MobiCom 2014.

Leonard Kleinrock was given the 2014 BBVA Foundation Frontiers of Knowledge Award "for his seminal contributions to the theory and practical development of the Internet," in the words of the jury's citation.
