Jean de Fontaney

Jean de Fontaney (1643–1710) was a French Jesuit mathematician. At Louis XIV's request, following an appeal from the Beijing missionary Ferdinand Verbiest, he set out with five scientifically trained Jesuits.

One remained in Siam, while the other four accompanied him to China. They reached Beijing in February 1688 and were received by the Kangxi Emperor, who kept Bouvet and Gerbillon at court. He returned to France in 1703 and died at La Flèche in 1710.
