January 18, 1743 – 14 October 1803 was a French philosopher, known as le philosophe inconnu, the name under which his works were published. In 1771, Saint-Martin left the army to become a preacher of mysticism. His conversational powers made him welcome in Parisian salons; but his zeal led him to England, where he made the acquaintance of William Law, the English mystic, and to Italy and Switzerland, as well as to the chief towns of France. At Strasbourg, in 1788, he met Charlotte de Boecklin, who introduced him to the writings of Jacob Boehme.
