**Edwin Thompson Jaynes**(July 5th, 1922 - April 30th, 1998) was Wayman Crow Distinguished Professor of Physics at Washington University in St. Louis. He wrote extensively on statistical mechanics and on foundations of probability and statistical inference.

A particular focus of his work was the construction of logical principles for assigning prior probability distributions; see the principle of maximum entropy, the principle of transformation groups and Laplace's principle of indifference.

His last book, *Probability Theory: The Logic of Science*, attempts to gather together the multiple threads of modern thinking about Bayesian probability and statistical inference, and to demonstrate the advantages of Bayesian techniques by comparison with the results of other approaches.
