Louis Claude de Saint-Martin (18 January 1743 – 14 October 1803) was a French philosopher, known as le philosophe inconnu, the name under which his works were published; he was an influential of the mystic and human mind evolution and became the inspiration for the founding of the Martinist Order. Léonce de Saint-Martin, composer and organist, was a distant relative of Louis-Claude de Saint-Martin. Life He was born at Amboise, into a family from the lesser nobility of central France. As his father wished, he tried first law and then the army as a profession. While in the garrison at Bordeaux, he came under the influence of Martinez de Pasqually, usually called a Portuguese Jew (although later research has revealed the probability that he was a Spanish Catholic), who taught a species of mysticism drawn from cabbalistic sources, and endeavoured to found thereon a secret cult with magical or theurgical rites. Around September 1768 Saint-Martin was introduced to the Elect Coëns. From 1768 until 1771, Saint-Martin worked at Bordeaux as secretary to Martinez de Pasqually. In 1771, Saint-Martin left the army to become a preacher of mysticism. Same year he was living with Jean-Baptiste Willermoz at Lyon, while writing his first book.
