The Osmothèque (from Greek osmē "scent" patterned on French bibliothèque "library") is the world's largest scent archive, a leading international research institution tracing the history of perfumery, based in Versailles with conference centers in New York City and Paris. Founded in 1990 by Jean Kerléo and other senior perfumers including Jean-Claude Ellena and , the Osmothèque is internationally responsible for the authentication, registration, preservation, documentation and reproduction of thousands of perfumes gathered from the past two millennia, archived at the Osmothèque repository and consultable by the public. Exclusive to the collection are countless rare masterpieces elsewhere discontinued or reformulated, including François Coty’s Chypre (Coty), Paul Parquet’s (Houbigant) and Aimé Guerlain's Jicky (Guerlain) as well as numerous personalized fragrances worn by historical figures such as Elizabeth of Poland, Napoleon and Eugénie de Montijo. Since 2008, Patricia de Nicolaï has served as the institution's president.
