Step 1 : Introduction to the question "4. Cambridge University's Lucasian Chair in Mathematics was endowed in 1664. Isaac Barrow was the first person to hold the title of Lucasian Professor of Mathematics; who was the second?"
...1. Isaac Newton 2. Robert Hooke 3. William Harvey 4. Edmund Halley Isaac Newton (1643-1727) is best known for his law of universal gravitation, and for his work in the field of optics. He shares credit with Gottfried Leibniz for the invention of infinitesimal calculus, though they worked independently and there was great controversy in their lifetime as to who had the greater claim to the invention. In common with all professors at Cambridge in the 1660s, the Professor of Lucasian Mathematics was required to take holy orders. However, at Newton's request, King Charles II abolished this requirement for the Lucasian Chair.
