Paul Sedir, pseudonym of Yvon Le Loup (1871-1926), was a pivotal figure of the fin-de-siecle French occult revival. He was a professor at the Ecole hermetique and Faculte des sciences hermetiques in Paris under the directorship of Papus, his first spiritual mentor. He practiced magic with the alchemist Albert Poisson and was initiated into almost all of the secret societies that occult Paris had to offer. Under the name Tau Paul, he was consecrated bishop of Concorezzo in the Eglise gnostique de France. He wrote widely on traditions of magic, mysticism, and esotericism, publishing over twenty books in French.
