Leonard Kleinrock (born in New York City, New York, USA, June 13, 1934, age 77 years) was a U.S. engineer and scientist known as the inventor of the internet or the father of the Internet. A professor of computer science at the UCLA Henry Samueli School of Engineering and Science, he made important contributions to several areas of computer networking, in particular to the theoretical side of computer networking. He is known for his contributions to the world of networking. His most famous and significant is “the theory of packet switching” through the paper in 1959 and in 1961 on the exchange of packets in relation to the technology package is the forerunner of the internet technology.

Kleinrock was born on June 13, 1934 in New York City, he graduated from the Bronx High School of Science in 1951 and received his Bachelor of Electrical Engineering and Computer science in 1957 from the City College of New York. In 1959 and 1963, he earned a master’s degree and a doctorate (Ph.D.) in electrical engineering and computer science from Massachusetts Institute of Technology. After completing pendidian he then joined the faculty at the University of California at Los Angeles (UCLA), School of Engineering and Applied Science where he worked there as a professor of computer science.
The first ARPANET message was sent by UCLA student programmer Charley Kline, at 10:30 pm, October 29, 1969 from boelter Hall 3420. He was mentored by Kleinrock.
