Techniques, histoire et sciences humaines Paris – London: empirical philosophy, invention and the Hartlib Circle Anthony TURNER * Abstract Using the papers of Samuel Hartlib, the author examines the empirical research into the natural world affected in France and England during the early 17th century, the making of the instruments needed for this research, and the transmission of technical ideas between France and England. Keywords : Hartlib, Gassendi, Mersenne, Oldenburg, making of instruments, trans- mission, magnetism, music. 123 Résumé. Paris – Londres : le cercle Hartlib, la philosophie empirique et l’invention À travers les papiers de Samuel Hartlib, l’auteur examine les recherches empiriques sur la nature menées en France et en Angleterre dans la première moitié du xviie siècle, la production des instruments nécessaires pour de telles recherches, ainsi que la trans- mission des idées techniques entre la France et l’Angleterre. Mots-clés : Hartlib, Gassendi, Mersenne, Oldenburg, fabrication d’instruments, trans- mission, magnétisme, musique. *. Historien indépendant, Anthony Turner travaille actuellement sur un dictionnaire bio-biblio- graphique des facteurs d’instruments de précision français et suisses, 1430-1930 ; sur une histoire des montres émaillées au xviie siècle (avec Catherine Cardinal) et sur les astrolabes en France au xvie siècle. Son catalogue d’instruments mathématiques dans les collections de la Bibliothèque nationale de France est sous presse. Contact : [[email protected]].
