Marie Baptiste née Dumont, also known as Mademoiselle le Prévost (or Prevot) (born in Bordeaux, France - died after 1786), was a French actress and singer. She spent a large part of her career in Sweden, where she was the perhaps most significant female star of the French Theatre during the Age of Liberty.
Marie Dumont, whose stage name was Mademoiselle le Prévost, was a member of the French Du Londel Troupe engaged on the orders by the Swedish queen Louisa Ulrika of Prussia in 1753. The Du Londel Company had performed in Copenhagen under the leadership of Jeanne du Londel and Pierre de Laynay when it arrived in Stockholm in 1753. They first shared with the Swedish Theatre in Bollhuset (during the 1753–54 season), but the building was soon reserved for them. They performed for the public in Bollhuset in winter, and for the royal court in the theatres of the royal palaces in summer. The troupe only contained twelve members at first, and in 1756, Louis Du Londel, the son of Jeanne Du Londel, travelled to The Hague and hired eight new members, of which Prévost was the most prominent one.
The French Theatre had a strict hierarchy, and Prévost was appointed prima donna in the conditions of her contract; she was to play the lead parts in tragedies, comedies from Comédie-Française and Comédie-Italienne, opéra comiques and breeches roles. She was also a singer, and participated in public concerts at Riddarhuset.
She was known as Madame Baptiste after she her marriage to another member of the troupe, Jacques-Baptiste Anselme (born 1732), whose stage name was Monsieur Baptiste. He was contracted as a second-part actor. Other notable members of the troupe was Marguerite Morel, the dancer and ballet master Elisabeth Soligny and Jeanne Louise Du Londel, daughter of director Jeanne Du Londel, who became the protegée of the court with her own carriage and dresser and was appointed instructor in French etiquette to Princess Sophia Albertine of Sweden.
