Jean-Hippolyte Michon (21 November 1806 – 8 May 1881) was a French priest, an archaeologist, and the founder of graphology.
Born in Laroche-près-Feyt, department of Corrèze, he studied in Angoulême and at the seminary in Église Saint-Sulpice, Paris, where in 1830 he was ordained into the priesthood.
He focused his energy towards scientific pursuits, in particular historical and archaeological research, publishing a number of works on the religious history of Charente.
In 1844, he published a treatise on Gallo-Roman monuments of Charente titled Statistique Monumentale de la Charente.
This work was denounced by the Catholic Church and added to the Index Librorum Prohibitorum.
Afterwards (1862–69) he published, under a pseudonym, a series of anti-clerical novels.
In 1868 he made the acquaintanceship of chirologist Adolphe Desbarrolles (1801–1886), who along with Michon, had an interest in handwriting analysis.
