One hundred years of X-rays. The contribution of Austrian scientists to the discovery and use of X-rays

In January 1896 experiments were made around the world with cathode-tubes to test Rontgen's paper ''a new kind of rays''. Mostly hands without pathological variations were X-rayed. At the same time in Vienna the clinical applications of X-rays were investigated. Two patients were successfully operated on after X-ray-examination. Remarkable for that time was an X-ray of an arteriogram of the arm of a dead person. It was made on 17th January 1896. The experiments with LENARD's cathode-tube were important for the discovery of X-rays. His experimentation was the inspiration for RONTGEN's discovery of X-rays.
