About the author
Writing as Dr. Jacobus X, Louis Jacolliot was a French barrister, colonial judge, author, and lecturer. He lived from 1837 to 1890, and sources connect the pseudonym directly to him rather than to a separate public figure.
Jacolliot spent part of his career in India and Tahiti, experiences that fed his travel writing and the exotic, often provocative tone of works published under the Jacobus X name. He was a notably productive writer, and the books associated with this pseudonym were presented as observations drawn from wide travel and medical or anthropological experience.
Today, Jacobus X is remembered less as a standalone literary personality than as one of Jacolliot's more intriguing bylines. For readers, the name carries a mix of curiosity, old-world sensationalism, and the 19th-century appetite for travel, scandal, and supposedly hidden knowledge.
