This award will fund my research trip to key archives in Rouen, Paris and Lyon. It will allow me to transcribe and analyse the letters of the eighteenth-century naturalist Marie Le Masson Le Golft (1749-1826). Born in Le Havre, she was a member of several academies, such as the Madrid Royal Academy of Education or the Royal Society of Bilbao. She was also one of the first women to be admitted as an honorary member of the Academies of Lyon (1785), Arras (February 1787) and Rouen. She exchanged extensive correspondence with members and secretaries of these institutions. Her letters—dispersed across multiple institutions and still largely understudied—offer a unique perspective on Enlightenment scientific networks. I plan to visit these archives to reconstruct these networks and to examine her unpublished scientific productions, including Balance of Nature [Balance de la nature]  (1784) and A General Sketch of Mankind [Esquisse d’un Tableau général du genre humain] (1787). This primary research is part of a broader project mapping eighteenth-century scientific and intellectual networks in which women played a crucial but often overlooked roles. The ADEFFI award, in collaboration with the French Embassy in Ireland, makes it possible to access these sources, advance my research and contribute to the recognition of women’s contributions to early modern science.
