Marie-Anne Paulze Lavoisier
French chemist and painter (1758-1836)
Marie-Anne Pierrette Paulze Lavoisier, later Countess of Rumford, (20 January 1758 – 10 February 1836) was a French chemist and noblewoman. Madame Lavoisier's first husband was the chemist and nobleman Antoine Lavoisier. She acted as his laboratory companion, using her linguistic skills to write up his work and bring it to an international audience. She also played a pivotal role in the translation of several scientific works and was instrumental to the standardization of the scientific method.
Biography
Her father, Jacques Paulze, worked primarily as a parliamentary lawyer and financier. Most of his income came from running the Ferme Générale (the General Farm) which was a private consortium of financiers who paid the French monarchy for the privilege of collecting certain taxes. Her mother, Claudine Thoynet Paulze, died in 1761, leaving behind Marie-Anne, then aged 3, and two sons. After her mother's death Paulze was placed in a convent where she received her formal education. She was for a time a pupil of the artist Jacques-Louis David.
At the age of thirteen, Paulze received a marriage proposal from the 50-year-old Count d'Amerval.
