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.
Guy Tachard remained in Siam where he was to have a major role, while Jean de Fontaney led the four remaining Fathers to China, where they arrived in February 1688. Upon their arrival in Beijing they were received by the Kangxi Emperor who was favorably impressed by them and retained Jean-François Gerbillion and Joachim Bouvet at the court.
