Marie-Anne Pierette Paulze (b. 1758, d. 1836) was the wife of Antoine Lavoisier. Married to him at 13 in 1771 (Lavoisier was about 28), she became his scientific colleague and his translator of English language scientific works. As a result of her close work with her husband, it is difficult to separate her individual contributions from his, but it is assumed that much of the work accredited to him bears her fingerprints.

Antoine Lavoisier was guillotined in the French Revolution. In 1805, she married another important early scientist, the physicist and inventor Benjamin Thompson, Count Rumford. This marriage was not happy -- he apparently married her for her money -- and they separated four years later.
