Louis Pouzin invented the datagram and designed an early packet communications network, CYCLADES. He studied at the �cole Polytechnique. His work influenced Robert Kahn, Vinton Cerf, and others in the development of TCP/IP protocols used by the Internet. Having participated in the design of the Compatible Time Sharing System, Pouzin wrote a program called RUNCOM around 1963/64. RUNCOM permitted the execution of contained commands within a folder, and can be considered the ancestor of the command-line interface and shell scripts. Pouzin was, in fact, the one who coined the term shell for a command language in 1964 or '65. Pouzin's concepts were later implemented in Multics by Glenda Schroeder at MIT. In 2013, he founded Savoir-Faire, an alternative root company, with Chantal Lebrument and Quentin Perrigueur.
