Etteilla
Etteilla, the pseudonym of Jean-Baptiste Alliette (1 March 1738 – 12 December 1791), was the French occultist and tarot-researcher, who was the first to develop an interpretation concept for the tarot cards and made a significant contribution to the esoteric development of the tarot cards to a wide audience (from 1783), and therefore the first professional tarot occultist known to history who made his living by card divination. Etteilla also influenced the French divination professional Marie Anne Lenormand.
