Inducted 2007

Paul Baran developed a fundamental concept behind today's advanced communications networking systems: digital packet switching.

Invention Impact

The digital packet concept is a paradigm shift from the circuit switched communications networks of the past. Packet switching enables the construction of digital networks with greater flexibility, reliability, robustness, and lower cost than circuit switching and now has become the new standard way of building communications networks. Baran based his network on a mesh network able to reconfigure itself to bypass non-working areas. To create this totally decentralized network, he divided the communications stream into message blocks, or “packets,” sent along various paths to eventually be rejoined into a whole at their destination.

Inventor Bio

Baran was born in Grodno, Poland and came to the U.S. at the age of two. In 1949, he earned his B.S. in electrical engineering from Drexel University and his M.S. from the University of California at Los Angeles in 1959. Following his graduation from UCLA, Baran was at the RAND Corporation where he designed his communication network to survive a first strike from the Soviet Union during the Cold War. Baran holds 31 patents for his work on several new communications technologies in part based upon the concept of packets.  He is the recipient of numerous honors, including the 2007 National Medal of Technology and Innovation.
