[From the early history of roentgen documentation]

By chance, eight X-ray plates dating from 1899 were found in 1986. Each of these glass plates shows the patient's name, the date of the examination were performed in Vienna by Prof. Franz Exner, who was a friend of W.C. Roentgen. The glass plates are 25 x 13 cm in area and 3 mm thick. One side is coated with silver bromide. Probably these are some of the earliest X-rays records in the history of radiology. Their quality is comparable with the quality that can be achieved today, even though the materials and the imaging method used were somewhat unsophisticated.
