CLEMENT, JACQUES (1567-1589), murderer of the French king Henry III., was born at Sorbon in the Ardennes, and became a Dominican friar. His mind appears to have become unhinged by religious fanaticism, and he formed a plan to kill Henry III. Having obtained letters for the king, he left Paris on July 31, 1589, and reached St. Cloud, the headquarters of Henry, who was besieging Paris. While Henry was reading the letters Clement mortally wounded him with a dagger which had been concealed beneath his cloak. The assassin was killed on the spot by the king's attendants.
