An 8 game match played at the Hotel du Louvre in Paris February 26 to March 3, 1859. Mongredien was President of he London Chess Club. Morphy had promised him a match, but as it was clear Morphy would be pressed for time as he passed through London on his way home, Mongredien traveled to Paris for the match. It was held privately with only Riviere and St Amant as eye witnesses.
