Pierre Varignon

Varignon gained his first exposure to mathematics by reading Euclid and then René Descartes' La Géométrie. He became professor of mathematics at the Collège Mazarin in Paris in 1688 and was elected to the Académie Royale des Sciences in the same year. In 1704, he held the departmental chair at Collège Mazarin and also became professor of mathematics at the Collège Royal. He was elected to the Berlin Academy in 1713 and to the Royal Society in 1718. Many of his works were published in Paris in 1725, three years after his death. His lectures at Mazarin were published in Elements de mathematique in 1731. Varignon was a friend of Isaac Newton, Gottfried Wilhelm Leibniz, and the Bernoulli family.
