Making Connections

When he was a student at the Massachusetts Institute of Technology (MIT), Ethernet inventor Bob Metcalfe briefly considered pursuing a career in tennis. He was captain of the 1968–1969 MIT tennis team, which had a record of 15 wins and 4 losses, and he was ranked sixth in New England in doubles, even while taking classes and holding a programming job at defense contractor Raytheon. That, unfortunately, was not enough to make a go of it. "There's playing pros and there's teaching pros," Metcalfe says. "I could easily be a teaching pro, but that just seemed boring. Metcalfe wrote his undergraduate thesis on a bus coming back from a tennis match and submitted it to Minsky at the last possible moment. The tennis world's loss was the computer world's gain, however, as Metcalfe went on to become an Internet pioneer, develop Ethernet, and help get it named a networking standard, actions that earned him the 2022 ACM A.M. Turing Award on the 50th anniversary of the invention of the technology.
