John Henry Pratt

John Henry Pratt

John Henry Pratt (June 4, 1809 - December 28, 1871) was a British clergyman and mathematician who devised a theory of crustal balance which would become the basis for the isostasy principle.

Pratt was born in London and educated as a mathematician at Cambridge University. He wrote "Pratt's Mechanical Philosophy", full title: "The Mathematical Principles of Mechanical Philosophy and their application to Elementary Mechanics and Architecture, but chiefly to The Theory of Universal Gravitation", a textbook of some 600 pages. While serving as the Archdeacon of India, Pratt arrived at his theory of crustal balance based upon a survey of India. He died in Ghazipur, India.
