General contextImportant defender of Isaac Newton and disseminator of Newtonian principles. Following his appointment as lecturer in experimental Philosophy at Hart Hall, Keill began giving lectures and performing experiments based on Newton's findings, instructing his students on the laws of motion, principles of hydrostatics & optics, and Newtonian propositions on light and colours. He became involved in the famous Newton calculus plagiarism controversy, alleged by Gottfried Liebniz. He defended Newton's Principia mathematica against a criticism levelled at it by Johann Bernoulli (Philosophical Transactions, July–September, 1714).
