Conversation with a pioneer: Larry Roberts on how he led the design and construction of the ARPANET

Abstract In this interview, the man who first managed the ARPANET project and made the network come in to existence, Dr. Lawrence G. Roberts, gives his account of how the ARPANET came to be. He contributes his perspective on the many other innovations made to computer science by ARPA in the 1960s and 1970s, and shares his view on the contentious origin narratives surrounding the Internet, ARPANET and packet switching. He also talks about his life-long friendship and collaboration with another Internet/ARPANET pioneer, Leonard Kleinrock.
