南怀仁
Jean de Fontaney had been a teacher of mathematics and astronomy at the College Louis le Grand. He was asked by king Louis XIV to set up a mission to China, following a request by Ferdinand Verbiest, in order to spread French and Catholic influence at the Chinese court with the pretext of transmitting scientific knowledge. Jean de Fontaney assembled a group of five other Jesuits to accompany him, all highly skilled in sciences, namely Joachim Bouvet, Jean-François Gerbillon, Louis-Daniel Lecomte, Guy Tachard, and Claude de Visdelou.
