ØRSTED, Hans Christian. [OERSTED] Experimenta circa effectum, etc. Expériences sur l’effet du conflict électrique sur l’aiguille aimantée.
Paris: Crochard, 1820.

First French edition of Ørsted's Latin paper 'Extperimenta circa effectum conflictus electrici in acun magneticam', 21 July 1820. The French translation of Ørsted's announcent of his discovery of electromagnetism is arguably the most influential edition of the numerous translations published that same year; it was through Arago's demonstrations, to the Paris Academy, of Ørsted's experiments that Ampère and Biot with Savart first learnt of Ørsted's results, and thus the new field of electrodynamics came to be founded.
