Soft cover. Zustand: Very Good. 1st Edition. Two offprints from: Sitzungsberichte der Würzburger Physikalisch-medicinischen Gesellschaft Würzburg, 1895-1896. 8vo (230 x 150 mm). 10; 9 [3] pp. Including 3 unnumbered pages of publisher's adverts in 2nd part. Publisher's original printed wrappers (minor repair to wrappers with reinforcement of spine edges and the inner wrappers silked, light soiling and wrinkling, weak vertical fold crease through 1st part). Housed in custom-made quarter morocco and cloth clamshell box. Internally clean and crisp throughout, with just a little age-toning and a trifle of dust-soiling to outer margins, but free of foxing or staining. Provenance: Arthur Edward Lyons (his bookplate to inner cover of clamshell box). Very good copies in the original wrappers which, due to paper quality, are often found embrittled and heavily chipped (here stabilized with thin, transparent fiber fabric not obscuring readability of the adverts). ---- FIRST EDITIONS, OFFPRINT ISSUES, OF RÖNTGEN'S FIRST COMMUNICATION OF THE DISCOVERY OF THE X-RAY. The most important contribution to medical diagnosis in a century, and the key to modern physics, Röntgen's paper was in immediate demand; there were five separate printings in six issues in the space of two months. The follow-up announcement, published a year later, introduces a scale for measuring X-ray intensity and an improved tube. "While performing experiments with a Crookes vacuum tube, a type of cathode-ray tube, Röntgen observed that some agent produced in the tube was causing barium platinocyanide crystals to fluoresce. Upon investigation he found that the fluorescence was caused by unknown rays (which he named 'X-rays') originating from the spot where cathode rays hit the glass wall of the vacuum tube. He announced his discovery in the present paper, which described the rays' photographic properties and their amazing ability to penetrate all substances, even living flesh. Although he was unable to determine the true physical nature of the rays, Röntgen was certain that he had discovered something entirely new, a belief soon confirmed by the work of other scientists such as Becquerel, Laue and the Curies. For his discovery, Röntgen was awarded the Nobel Prize in physics for 1901 . . . Röntgen submitted his paper for publication in the obscure Sitzungs-Berichte of the Würzburg Physical-Medical Society, a strategy deliberately employed to assure fast publication" (Norman 1841). "Their importance in surgery, medicine and metallurgy is well known. Incomparably the most important aspect of Röntgen's experiments, however, is his discovery of matter in a new form, which has completely revolutionized the study of chemistry and physics. Laue and the Braggs have used the X-rays to show us the atomic structure of crystals. Moseley has reconstructed the periodic table of the elements. Becquerel was directly inspired by Röntgen's results to the investigation that discovered radioactivity. Finally, J.J. Thomson enunciated the electron theory as a result of investigating the nature of the X-rays" (PMM 380).

FIRST EDITIONS. Original printed wrappers, with the ownership signature of Dr. H. Michaelis (?) on front wrapper. Preserved in a folding clamshell box. PMM, 380. First edition of the first published reports on the sensational discovery of X-rays -- a form of light invisible to the eye which had never before been observed. With remarkable insight, Röntgen first suspected a new phenomenon while investigating the florescence produced near a Crookes tube in late 1895. He immediately began a thorough set of experiments that revealed the uses of the new ray for science and medicine. Hundreds of articles and books on the new Röntgen-rays were published in the year following their discoverer's announcement. Röntgen (1845-1923), a German physicist, was awarded the first Nobel Prize in physics in 1901. His research spanned nearly all the branches of physics, from work with gases and solutions to investigations of the electromagnetic theory of Maxwell.
