Todhunter, ISAAC

Todhunter, ISAAC, mathematician, was born at Rye in 1820, studied at University College, London, served some time as a tutor, and so was enabled to enter St John's College, Cambridge, where in 1848 he graduated senior wrangler and Smith's prizeman. Elected to a fellowship in his college, he became eventually its principal mathematical lecturer, and ere long his handbooks of Algebra, Geometry, Conic Sections, Trigonometry, Mensuration, and Mechanics made his name known, if not always honoured, in every schoolroom in England. For more advanced students his indefatigable energy and rare faculty of exposition provided also manuals on the Differential and the Integral Calculus, Analytical Statics, Plane Co-ordinate Geometry, and Analytical Geometry. He died 1st March 1884.
