Hélène Smith was the séance name of Catherine Élise Müller, a Swiss medium whose trance narratives described a former life as an Indian princess, another as Marie Antoinette, and journeys to Mars. Psychologist Théodore Flournoy documented those accounts and interpreted them as products of somnambulism, suggestion and unconscious imagination—not proof of reincarnation or extraterrestrial contact.
Who was Hélène Smith?
Smith was the pseudonym used by Catherine Élise Müller. Flournoy, a professor of psychology at the University of Geneva, began observing her séances in late 1894. His account records what Smith experienced and said, while also presenting his own analysis; it is not independent confirmation that her claimed past lives or Martian encounters happened.
Smith and her spirit-control, Leopold, treated her trance experiences as evidence of lives and communications beyond her ordinary identity. Flournoy approached them as psychological phenomena. Keeping those perspectives distinct is central to understanding the case.
What did Smith say she experienced?
Flournoy grouped Smith’s narratives into three cycles, which he called “romances.” They were reported in trance, not established biographies or travel accounts.

The Hindu cycle: Simandini
Smith described a former life as Simandini, the wife of a Hindu prince. The title’s reference to an Indian princess captures the substance of this claim, but the story is Smith’s account of a past life.
The Royal cycle: Marie Antoinette
In another narrative, Smith identified with Marie Antoinette, the French queen. Flournoy treated this as a separate cycle from the Indian story.
Rank #2
The Martian cycle
Smith described scenes on Mars, including its inhabitants, animals and landscapes. She also produced speech and writing that she and Leopold presented as a Martian language. These accounts form the most distinctive part of the case because Flournoy and linguist Ferdinand de Saussure examined the language as well as the narratives.
Was Smith’s Martian language really extraterrestrial?
Smith and Leopold insisted that the language came from Mars. Flournoy compared its features with French and argued that it had terrestrial sources. A later scholarly summary describes his explanation as a blend of languages Smith knew, shaped by unconscious creativity, suggestion, cryptomnesia, surrounding ideas and latent emotional tendencies. That is Flournoy’s interpretation of the case, not a modern diagnosis or a settled finding that establishes exactly how the language was formed.

Rank #3
Flournoy stated his skeptical aim directly in the 1900 English edition: “What would happen if I made up my mind to strike this strange conviction a telling blow, and demonstrate that the pretended Martian was only a chimera, a product, pure and simple, of somnambulistic autosuggestion?” The wording makes clear that he was arguing against Smith’s explanation, not neutrally endorsing it.
How should the case be read today?
The record preserves two different kinds of evidence: Smith’s séance testimony and trance writing, and Flournoy’s comparative psychological and linguistic analysis. The first documents what she claimed and produced; the second offers an interpretation of those materials. Neither makes the supernatural claims a demonstrated fact.
Flournoy’s book is valuable as a historical case study in mediumship, somnambulism and the interpretation of unusual experiences. It should be read as his account of Smith and his argument about her narratives, rather than as proof that she was an Indian princess, Marie Antoinette, or a visitor to Mars.

Flournoy’s French study, Des Indes à la planète Mars: Étude sur un cas de somnambulisme avec glossolalie, is dated to the end of 1899 in the Bibliothèque de Genève’s guide, which also captions a Paris 1900 edition. The English translation, From India to the Planet Mars: A Study of a Case of Somnambulism with Glossolalia, translated by Daniel B. Vermilye, was published by Harper & Brothers in 1900. Open Library catalogs that English edition and later editions, including a 1994 Princeton University Press edition.
