Allan Kardec (Hippolyte Léon Denizard Rivail)

Allan Kardec, born Hippolyte Léon Denizard Rivail, was a 19th-century French educator and philosopher who founded Spiritism, a spiritual movement based on the study of spirits and their interactions with the living. Through systematic investigation of mediumship and spiritual phenomena, Kardec aimed to understand the moral and philosophical teachings of spirits, emphasizing ethics, reincarnation, and communication with the deceased. His key works, including "The Spirits’ Book," laid the foundation for Spiritism as a moral and philosophical doctrine, promoting personal growth, compassion, and respect for spiritual evolution.
