Alan Kardec

Rivail wrote under the name "Allan Kardec", allegedly following the suggestion of a spirit identified as Truth. On 18 April 1857, Rivail (as Allan Kardec) published his first book on Spiritism, The Spirits' Book, comprising a series of answered questions (502 in the first edition and 1,019 in later editions) exploring matters concerning the nature of spirits, the spirit world, and the relationship between the spirit world and the material world. This was followed by a series of other books, including The Medium's Book, The Gospel According to Spiritism, Heaven and Hell and The Genesis According to Spiritism, and by a periodical, the Revue Spirite, which Kardec published until his death. Collectively, the books became known as the Spiritist Codification.

According to “My predictions concerning spiritualism” as he himself described in his manuscript written between 1855 and 1856, "in May 1855, he met a certain Mr. Fortier, a magnetizer, who took him to Madame de Plainemaison, a medium who lived in the Rue de la Grange Bateliere in Paris, just a step away from the Opera House. In the presence of other guests for the session, he entered into communication with a spirit named Zephyr, who gave him the mission of being the spokesman of the Dead. For him, it was a revelation. He was there, for the first time, witnessing the phenomenon of turntables jumping and running".

In 1839, with a new partner, Mr. Maurice Delachatre, a merchant, he created a so-called "exchange" bank, which aimed to facilitate commercial transactions and thus create new opportunities for trade and industry, in order to support in default of pecuniary resources for the natural products. The duration of the trading bank was fixed by the Chamber of Commerce and Industry at ten years.

On February 6, 1832, he married Amélie Gabrielle Boudet.
