David Reeves Boggs was an American electrical engineer and computer scientist who, with Robert Metcalfe, co-invented Ethernet at the Xerox Palo Alto Research Center in the early 1970s. While Metcalfe is usually credited with the founding concept and the memo that named the system, Boggs was the hands-on builder who made the hardware work, and the two presented the result as equal co-authors.
Boggs joined PARC as a member of the research staff and brought a deep practical knowledge of electronics and radio. He and Metcalfe constructed the first experimental Ethernet to connect PARC’s Alto personal computers over a shared coaxial cable, designing the transceivers, controllers, and signaling that let many machines share one “Ether” without a central controller. Their collaboration paired Metcalfe’s networking theory, rooted in the ALOHAnet and ARPANET, with Boggs’s engineering of the physical layer.
The partnership is recorded most durably in their July 1976 Communications of the ACM paper, “Ethernet: Distributed Packet Switching for Local Computer Networks,” which describes operational experience with about 100 nodes along a kilometer of cable. Boggs is also named as a co-inventor, alongside Metcalfe, Charles Thacker, and Butler Lampson, on US Patent 4,063,220, “Multipoint Data Communication System With Collision Detection,” assigned to Xerox.
Beyond Ethernet, Boggs contributed to internetworking research; he worked with the PARC Universal Packet (PUP) protocols, an influential predecessor to the modern Internet protocols, and later pursued doctoral work in electrical engineering at Stanford. His role is sometimes overshadowed by Metcalfe’s later fame as a 3Com founder and public figure, but the primary record, the co-authored paper and the shared patent, places him squarely as a co-creator of the technology.
David Boggs died in 2022. The contemporaneous primary sources from the 1970s remain the clearest testimony to his contribution: in the documents that introduced Ethernet to the world, his name stands beside Metcalfe’s as an equal inventor of the local-area network.
