William L. Harper is Professor Emeritus at the University of Western Ontario, where he has taught since 1970. He has held positions as a visiting Professor at the University of Pittsburgh, Princeton University, and the California Institute of Technology. From 2002 to 2005 he served as President of the Canadian Society for History and Philosophy of Science, having served as First Vice President from 1999 to 2001. He has also served twice on the Governing Board of the Philosophy of Science Association, and was Representative of the Association of Symbolic Logic to the American Association for the Advancement of Science between 1982 and 1988.

In virtue of the significance of Newton's result for the history of science, Harper's book is an important contribution.
