Early Trade Catalogue of X-Ray Equipments, With a Hand Radiograph

Köln a. Rh. [Cologne]: E. Leybold’s Nachfolger, [June, 1896]. First edition. With an original radiograph mounted on the verso of the front panel. With an advertisement flyer of “Hittdorf’she Röhre”. In publisher’s half cloth, illustrated front panel. 18 p.

A very early trade catalogue of X-ray equipments and other components. Illustrated with an original radiograph of a hand, produced in in Leybold’s studio in 1896.

X-ray was discovered by the German scientist Wilhelm Röntgen on November 8, 1895. It was also him, who made the first X-ray image, Hand mit Ringen (Hand with Rings) of his wife's hand, taken a few weeks later on December 22. His original paper, Ueber eine neue Art von Strahlen (On A New Kind of Rays), was published on 28 December 1895.

E. Leybold’s Nachfolger (today Leybold GmbH) is a Cologne-based trading company, which was focused on the distribution of pharmaceutical and physical-technical equipment and apparatus. The present publication, their 1896 June catalogue of X-ray equipments is – to our best knowledge – the first trade catalogue dedicated entirely to X-ray equipments, and it is among the earliest publications of an original radiograph.

The catalogue is not merely offering the equipments but also describes their function, use and development, such as the technological development of the X-ray (focus) tubes, with reference to Röntgen’s second paper on March 9, 1896. The inventory offers different tubes and recommends inductors and power sources, to use, as well as apparatuses and compartments for photographic experiments with the X-ray.

The company also offers equipments for experimenting alternate currents and electromagnetic waves described by Tesla and Hertz.

With a contemporary advertisement flyer of Hittdorf’she Röhre, a vacuum tube designed by Johann Wilhelm Hittorf.
