Louis Pouzin
How the hell can I have lived and breathed tech since before the invention of the internet and not heard of the man who invented and implemented its key end-to-end networking design, and even invented and coined the term 'shell' for the command interpreter that became ubiquitous on every computer with a human interface?
How the hell does that happen? I remain an idiot.
