  Leibniz's final years were bleak. He was engaged in a vituperative debate with Newton and his followers over the priority of the discovery of the calculus, even being accused of stealing Newton's ideas. (Most historians of mathematics now claim that Newton and Leibniz developed their ideas independently: Newton developing the ideas first with Leibniz the first to publish.) And at the court he was mocked for his wig and old-fashioned clothing (think 1670s Paris!). When Georg became George, the acrimony surrounding Leibniz in England was so great that Leibniz was asked to remain in Hanover rather than follow his employer to London. Leibniz died November 14, 1716.
