Röntgen also spelled ROENTGEN German
physicist who was a recipient of the first Nobel
Prize for Physics, in 1901, for his discovery of
X rays, which heralded the age of modern
physics and revolutionized diagnostic medicine.
In 1895, while experimenting with electric current flow in a partially
evacuated glass tube (cathode-ray tube), Röntgen observed that a
nearby piece of barium platinocyanide** gave off light when the tube was
in operation. He theorized that when the cathode rays (electrons) struck
the glass wall of the tube, some unknown radiation was formed that
traveled across the room, struck the chemical, and caused the
fluorescence.
Further investigation revealed that paper, wood, and aluminum, among
other materials, are transparent to this new form of radiation. He found
that it affected photographic plates, and, since it did not noticeably exhibit
any properties of light, such as reflection or refraction, he mistakenly
thought the rays were unrelated to light. In view of its uncertain nature, he
called the phenomenon X radiation, though it also became known as
Röntgen radiation. He took the first X ray photographs, of the interiors of
metal objects and of the bones in his wife's hand. © 1999-2000
