On January 13, 1896, R繹ntgen presented his work to Emperor Wilhelm II in Berlin. The modest discoverer spoke for the first and only time on his 'New Kind of Ray,' before the Physical Medical Society of the University of W羹rzburg. When he entered the auditorium, a veritable storm of applause arose, which was repeated many times during the evening. R繹ntgen modestly began to talk about his work. He then mentioned the investigations with cathode rays made by Hertz, Lenard, and others, and said that his experiments along the same lines resulted in his discovery. He related how he first observed the fluorescence of a small piece of paper painted with barium platinum cyanide and how he quickly found out that the cause for this fluorescence came from the carefully covered Hittorf tube itself, and not from any other part of the high-tension circuit. Then, he used a photographic plate and the experiment was successful. After this, R繹ntgen made an X-ray picture (radiograph) of Albert von Kolliker's hand at a public lecture.
