Beginning in the mid-1990s, Leonard Kleinrock sought to be recognized as the "father of modern data networking". However, Kleinrock's claims that his work in the early 1960s originated the concept of packet switching and that this work was the source of the packet switching concepts used in the ARPANET are disputed, including by Robert Taylor, Paul Baran, and Donald Davies. Baran and Davies are recognized by historians and the U.S. National Inventors Hall of Fame for independently inventing the concept of digital packet switching used in modern computer networking including the Internet.
