Je suis pas un historien de l'informatique, mais pour ma part, a part des unix et des OS de MS, j'ai vu ça nul part (en gros, c'est à dire ni sur des macos, ni sur des TI 99/4A :) ). Mais on peut lire un peut partout que ça viens bien d'UNIX ou peut être de MULTICS son ancêtre:
The pipeline concept and the vertical-bar notation was invented by Douglas McIlroy, one of the authors of the early command shells, after he noticed that much of the time they were processing the output of one program as the input to another. The idea was eventually ported to other operating systems, such as DOS, OS/2, Windows NT, and BeOS often with the same notation.
The robot in the icon for Apple's Automator, which also uses pipeline concept to chain repetitive commands together, holds a pipe as recognition of the application's Unix heritage.[1]

A propos de Douglas McIlroy: «
Dr. McIlroy is best known for having invented:
* The pipes and filters architecture of Unix as seen in the Unix pipeline implementation.
* The entire concept of software componentry
* Several Unix tools, such as spell, diff, sort, join, graph, speak, tr, etc.
