Professor Christopher Stewart Wallace (26 October, 1933—7 August, 2004) was an Australian computer scientist notable for having devised: The minimum message length principle — an information-theoretic principle in statistics, econometrics and machine learning which can be seen both as a mathematical formalisation of Occam's Razor and as an invariant Bayesian method of model selection and point estimation, The Wallace tree multiplier, a variety of random number generators, and a range of other works - see, e.g., Christopher Stewart Wallace memorial special issue of the Computer Journal .

  • Professor Christopher Stewart Wallace (26 October, 1933—7 August, 2004) was an Australian computer scientist notable for having devised: The minimum message length principle — an information-theoretic principle in statistics, econometrics and machine learning which can be seen both as a mathematical formalisation of Occam's Razor and as an invariant Bayesian method of model selection and point estimation, The Wallace tree multiplier, a variety of random number generators, and a range of other works - see, e.g., Christopher Stewart Wallace memorial special issue of the Computer Journal . He was appointed Foundation Chair of Information Science at Monash University in 1968 at the age of 34, and Professor Emeritus in 1996. Wallace was a fellow of the Australian Computer Society and in 1995 he was appointed a fellow of the ACM "For research in a number of areas in Computer Science including fast multiplication algorithm, minimum message length principle and its applications, random number generation, computer architecture, numerical solution of ODE's, and contribution to Australian Computer Science." Wallace received his PhD (in Physics) from the University of Sydney in 1959. He was married to Judy Ogilvie, the first operator of SILLIAC, one of Australia's first computers which was launched on the 12 of September 1956 at the University of Sydney . He also engineered one of the world's first Local Area Networks in the mid 1960s . (en)
