Turing Award Winner Bob Metcalfe

"Today Metcalfe was named the winner of the A.M. Turing Award, an annual prize considered the highest honor in computer science, for his part in ushering in our hyperconnected age. Fifty years ago, Metcalfe helped invent Ethernet, the local networking technology that links personal computers around the world to the global internet. He also played a central role in standardizing and commercializing his invention." https://www.quantamagazine.org/bob-metc...

Also, the article has a good bit of early networking history.
