    Room dedicated to Prof Mrs Röntgen

    Professor Röntgen discovered the existence of X-rays on November 8 , 1895 through experiments in his laboratory in Würzburg. After 6 weeks of further experiments he invited his wife to his laboratory on the evening of December 22nd and demonstrated to her how a photo of her left hand looked like after radiation. The invention and properties of x-rays were carefully described and officially published on December 28 ,1895 In the "WÜRZBURG ROOM" we reconstruct the evening of December 22nd and show the equipment used for the "radiography" of Mrs Röntgen’s left hand.
