“Seems Ethernet Does Not Work in Theory, Only in Practice”

(p. A21) David Boggs, an electrical engineer and computer scientist who helped create Ethernet, the computer networking technology that connects PCs to printers, other devices and the internet in offices and homes, died on Feb. 19 [2022] in Palo Alto, Calif.

. . .

In the spring of 1973, just after enrolling as a graduate student at Stanford University, Mr. Boggs began an internship at Xerox PARC, a Silicon Valley research lab that was developing a new kind of personal computer. One afternoon, in the basement of the lab, he noticed another researcher tinkering with a long strand of cable.

The researcher, another new hire named Bob Metcalfe, was exploring ways of sending information to and from the lab’s new computer, the Alto. Mr. Metcalfe was trying to send electrical pulses down the cable, and he was struggling to make it work. So Mr. Boggs offered to help.

Over the next two years, they designed the first version of Ethernet.

“He was the perfect partner for me,” Mr. Metcalfe said in an interview. “I was more of a concept artist, and he was a build-the-hardware-in-the-back-room engineer.”

. . .

Before becoming the dominant networking protocol, Ethernet was challenged by several other technologies. In the early 1980s, Mr. Metcalfe said, when Mr. Boggs took the stage at a California computing conference, at the San Jose Convention Center, to discuss the future of networking, a rival technologist questioned the mathematical theory behind Ethernet, telling Mr. Boggs that it would never work with large numbers of machines.

His response was unequivocal. “Seems Ethernet does not work in theory,” he said, “only in practice.”
