Works & Achievements
Missy practiced sculpture in her studio and exhibited some of her works, an artistic pursuit that was exceptional for an aristocrat at the time.
A pantomime performed at the Moulin Rouge in which Missy, under the name “Yssim,” played a scholar opposite Colette as a mummy; the closing kiss set off a resounding scandal.
She appeared on several Parisian stages in pantomimes, combining her love of spectacle with her provocative public life.
Missy encouraged and funded Colette's early days in music hall and in writing, and lent her the Villa Rozven, which inspired several of her books.
Anecdotes
On 3 January 1907, Mathilde de Morny stepped onto the stage of the Moulin Rouge in a pantomime titled “Rêve d'Égypte” (Dream of Egypt), under the pseudonym “Yssim” (Missy spelled backwards). Dressed as a scholar, she kissed her friend, the writer Colette, who was playing a revived mummy, right there on stage. The hall erupted in whistles, shouts and flying objects, and the police had to step in. The show was banned the very next day.
The daughter of the Duke of Morny, Mathilde had herself called “Missy,” “Uncle Max,” or “Monsieur le Marquis.” She wore men's suits, kept her hair short and smoked cigars, at a time when a regulation still forbade women from wearing trousers without permission from the police.
Beyond the music halls, Missy was a sculptor and worked in her own studio, handling clay and modelling tools. Such serious artistic work was very rare at the time for a woman of the high aristocracy.
Her father, the Duke of Morny, was the half-brother of Emperor Napoleon III: Mathilde was thus born at the very top of the Second Empire's aristocracy. Yet she chose to lead a free and provocative life, far from the conventions imposed on women of high society.
Missy owned a villa called Rozven, on the Breton coast near Saint-Malo, which she made available to Colette. The writer spent many summers there and drew from it the inspiration for several of her books.
Primary Sources
In it, Colette paints the portrait of “la Chevalière,” a society woman dressed as a man and inspired by Missy, whom she describes with tenderness for her manly elegance and her delicacy.
The newspapers report the uproar in the Moulin Rouge hall when the Marquise de Morny and Colette kiss on stage; faced with the scandal, the police prefecture had the pantomime banned.
The text requires any woman wishing to dress as a man to first obtain authorization from the police prefecture — a rule still invoked in Missy's day.
