Harold Jeffreys (1891–1989) spent all his adult life in Cambridge, part of it as Plumian Professor of Astronomy and Experimental Philosophy, and is best known as a geophysicist. His interest in the analysis of data led to his development of a statistical method, now called Bayesian, based on the calculus of probability. He viewed probability as measure, common to all rational persons, unlike the subjective view. In the development of this attitude, he introduced the concept of invariance.
