She was born on 13 June 1881, in Paris, Île-de-France, France.[2] Her father was the sculptor René Rozet, who married her mother in 1895, fourteen years after her birth.
Rozet was a member of the Union of Women Painters and Sculptors (UFPS; French: Union des femmes peintres et sculpteurs).[3] The UFPS demanded L’École Nationale Supérieure des Beaux-Arts de Paris (ENSBA; also known simply as Beaux-Arts de Paris) to allow Rozet to attend, because during this time women were not allowed entrance to the school.[3] Rozet was the first female student to attend ENSBA in 1896, and there she studied under Laurent Marqueste.[3]
Starting in 1904, she began exhibiting at Salon des Artistes Français.[3] In 1905, she was accepted on a trial basis for the Prix de Rome (an organization which also did not have many female participants), however she did not go beyond the "preparatory examination".[4]
