History

Ethernet was originally developed at Xerox PARC in 1973–1975.[1] Robert Metcalfe and David Boggs wrote and presented their "Draft Ethernet Overview" before March 1974. In March 1974, R.Z. Bachrach wrote a memo to Metcalfe and Boggs and their management, stating that "technically or conceptually there is nothing new in your proposal" and that "analysis would show that your system would be a failure." This analysis was flawed in that it ignored the "channel capture effect", though this was not understood until 1994. In 1975, Xerox filed a patent application listing Metcalfe and Boggs, plus Chuck Thacker and Butler Lampson, as inventors (U.S. Patent 4,063,220 : Multipoint data communication system with collision detection). In 1976, after the system was deployed at PARC, Metcalfe and Boggs published a seminal paper.[2]
