Born in 1758, Marie-Anne Pierette Paulze married–at the age of 13–Antonie-Laurent Lavoisier, the chemist famous for the law of conservation of mass. Following her husband's interests, Madame Lavoisier made a serious study of chemistry herself and thereafter played an active role in her husband's scientific experiments and discoveries. In addition to her work in the laboratory, she translated books from English to French to allow Antoine-Laurent to further his scientific knowledge. Following her husband's execution, she protested vehemently agaisnt the arbitrary nature of the proceedings. She duly attended to the publication of his memoirs posthumously.
