Gottfried Wilhelm LeibnizBorn 1 Jul 1646; died 14 Nov 1716 at age 70. German philosopher, mathematician and political adviser, important both as a metaphysician and as a logician, and also distinguished for his independent invention of the differential and integral calculus. Through meeting with such scholars as Christiaan Huygens in Paris and with members of the Royal Society, including Robert Boyle, during two trips to London in 1673 and 1676, Leibniz was introduced to the outstanding problems challenging the mathematicians and physicists of Europe. Leibniz's independently discovered differential and integral calculus (published 1684), but became involved in a bitter priority dispute with Isaac Newton, whose ideas on the calculus were developed earlier (1665), but published later (1687). |
