1845 – Roentgen – bio

Wilhelm Conrad Rontgen was born in Prussia (which is the Rhine province of western Germany today) in 1845 and was a physicist who is known for his discovery of x-rays. Hittorf, Pulyui, Tesla, Sanford and Lenard all noticed fluorescence in materials caused by the strange invisible rays emanating from electrified vacuum tubes, but it was Roentgen who first called them X-rays and did extensive investigations into the phenomenon. He discovered that many materials seemed to be transparent to the rays and that they could be used to create images of human skeletal structure.
