Raymond ReiterFRSC (; June 12, 1939 – September 16, 2002) was a Canadian computer scientist and logician. He was one of the founders of the field of non-monotonic reasoning with his work on default logic, model-based diagnosis, closed-world reasoning, and truth maintenance systems. He also contributed to the situation calculus. Awards and honorsHe was a Fellow of the Association for Computing Machinery (ACM), an AAAI Fellow, and a Fellow of the Royal Society of Canada. He won the IJCAI Award for Research Excellence in 1993. PublicationsR. Reiter (1978). On closed world data bases. In H. Gallaire and J. Minker, editors, Logic and Data Bases, pages 119–140.
