Bernadette Bensaude-Vincent is a French philosopher, professor emeritus at University of Paris 1 Pantheon-Sorbonne and a member of the French Academy of Technology. Bensaude-Vincent has published more than twenty books and 150 articles and essays. In 1993 she published Histoire de la chimie with Isabelle Stengers, which was translated into English as A History of Chemistry in 1997. The authors received the Prix Jean-Rostand for this work. In the early 1990s, Bensaude-Vincent directed a research program on science and the public. In 1997, she was appointed professor of History and Philosophy of Science at Université Paris-X Nanterre. Laterly she has called for a new alliance between science and ethics, co-directing a joint ANR/DFG project which sought to distinguish between science and technoscience. Between 2010 to 2015, she was a professor at the University of Paris 1 Pantheon-Sorbonne and the director of The Center for Study of Technology, Knowledge & Practice (Centre d'étude des techniques, des connaissances et des pratiques, CETCOPRA). In addition she has been a visiting professor at various universities around the world, a visiting scholar at Max Planck Institute for the History of Science in Berlin (2001) and Doctor Honoris Causa of Lisbon University in 2017. In November 2021 she received the George Sarton Medal, the highest distinction of the History of Science Society, the Franklin-Lavoisier medal in 2024, and an award from the Society of Technology and Philosophy in 2025.
