Schall, Johann Adam von, Jesuit missionary to China, born at Cologne; was received with honours at the Imperial Court; obtained permission to preach, and founded churches to the spread of Christianity, a privilege which was revoked by the next emperor; he was subjected to imprisonment, which shortened his life (1591‒1669).
