 From Hoare's book "Communicating Sequential Processes", pp 241-2
(http://www.usingcsp.com/):

"The idea was first propounded by Conway who illustrated it by examples  
similar
to 4.4 X2 and X3, except that all components of a pipe were expected to
terminate successfully instead of running forever. He proposed that the  
pipe
structure should be used for writing a multiple-pass compiler for a  
programming
language."

Hoare refers to M.E. Conway's "Design of a Separable Transition-Diagram  
Compiler,"
Comm. ACM 6 (7), 8?15 (1963).
