She was a member of the Comédiens du Roi at the Hôtel de Bourgogne under her mentor Valleran le Conte between 1607 and 1612.
Rachel Trépeau is the first actress named in a legal contract in the 17th-century: on December 1, 1607 she was included in an association of actors led by Valleran, “represented” by Nicolas Gasteau.
[2] In 1610, she and Gasteau jointly held one-half shares in another troupe led by Valleran.
Trépeau signed several legal documents between 1610 and 1612, and as she did not need the permission of a husband, which had been necessary for a wife in the law of the time period, she was evidently not married, but Nicolas Gasteau did represent her on occasion.
[2] While the roles played by the actors in Paris during this time period is generally not known, she was evidently a principal actress of the company, and the only contemporary female actor sharing in the income of the company Comediens du roi.
