Barry James Mailloux (died May 26, 1982) obtained his M.Sc in Numerical Analysis in 1963. From 1966 he studied at Amsterdam's Mathematisch Centrum under Adriaan van Wijngaarden.
He was the "first et al editor" of the original Report on the Algorithmic Language ALGOL 68 and the Revised Report on the Algorithmic Language ALGOL 68.
In 1968 he returned to the University of Alberta as an Assistant Professor in the Department of Computing Science. His work on ALGOL 68 put the University of Alberta on the map as a center for ALGOL 68-related activity.
Barry's student Chris Thomson and friend Colin Broughton established Chion Corporation, which produced FLACC (Full Language Algol 68 Checkout Compiler). FLACC proved Barry's contention that ALGOL68 could indeed be implemented, contrary to the loud complaints from e.g., Edsger Dijkstra.
