01 · A life in computing
The person behind the work
Bob Metcalfe co-invented Ethernet at Xerox PARC with David Boggs, developing a practical way for nearby computers to share a communication medium. He later founded 3Com and helped turn Ethernet from a laboratory system into an industry standard and commercial technology. His career also includes teaching, venture capital, and research. The award recognizes invention, standardization, and commercialization together, reflecting how networking technologies reach broad use.
The contribution, explained
Robert Metcalfe invented Ethernet and advanced its standardisation and commercial use. The original system let computers communicate over a shared local medium, coordinating access and handling collisions. Ethernet then evolved into a broad family of networking technologies with very different physical and switching arrangements.
Why it matters
Common local-network standards helped connect computers, printers and other resources across organisations.
