In France, the doctors T. Barthélémy and P. Oudin are credited with having taken the first medical X-ray. Born in Lorraine, Barthélémy learnt of the discovery of X-rays by Röntgen from a German journal. He repeated the same experiment with Oudin with better results. The first medical X-rays were presented, under their names, by Henri Poincaré on the 20th January 1896 at the Académie des Sciences at a lecture titled "A Photograph of the bones of a hand taken by means of an X-ray" discovered by Professor Röntgen.
