Philippe Lebrun, trained at the École des Mines and Caltech, worked on major accelerator projects at CERN and led international scientific collaborations. His long interest in the history and philosophy of science informs this lecture.
The session examines Jérôme Lalande’s scientific achievements and intellectual influence across the Enlightenment, from astronomy and navigation to popular science and the metric system. It also places his work in broader debates of the period, highlighting original documents and the legacy of a scholar whose impact reached far beyond astronomy.
