A French intellectual who codified conversations with the dead, founding Spiritism, a movement that swept 19th-century Europe and Brazil.
Born Hippolyte Rivail, a methodical educator with a background in science, his life took a radical turn in middle age. Intrigued by the popular fad of table-turning séances in 1850s Paris, he approached the phenomena not as superstition but as a subject for systematic study. Adopting the pen name Allan Kardec, he compiled and analyzed thousands of mediumistic communications, publishing 'The Spirits' Book' in 1857. This work, and the four that followed, presented Spiritism as a philosophical doctrine: a belief in the evolution of the soul through multiple lives, guided by benevolent spirits. Kardec’s cool, rational framing gave spiritualist ideas a structured, almost academic credibility. His books found a massive audience, particularly in Brazil, where his teachings took root and evolved into a major religious and cultural force, blending with local beliefs to form a unique spiritual landscape.

The name 'Allan Kardec' was supposedly given to him by a spirit during a séance, claiming it was his name in a previous Celtic incarnation.
He was initially a skeptic of spirit phenomena, investigating them only after being invited by a friend.
His tomb in Père Lachaise Cemetery in Paris is a pilgrimage site for Spiritists, often covered in flowers and notes.
He was a respected educator prior to his Spiritist work, having written textbooks on arithmetic, grammar, and French.
