モンモランシー公
The Benois family was a family of prominent 19th- and 20th-century Russian artists, musicians and architects, descended from French confectioner Louis Jules (Leonty Nikolaevich) Benois (1770/1772?-1822), cook-confectioner to the Duke of Montmorency, who moved to Russia in 1794 after the French Revolution and became a royal headwaiter.
