Wilhelm Conrad Rontgen (27 March 1845 – 10 February 1923) was a German physicist, who, on 8 November 1895, produced and detected electromagnetic radiation in a wavelength range today known as x-rays or Rontgen rays.
In 1865, he tried to attend the University of Utrecht without having the necessary credentials required for a regular student. Hearing that he could enter the Federal Polytechnic Institute in Zurich, by passing its examinations, he began studies there as a student of mechanical engineering. In 1869, he graduated with a Ph.D. from the University of Zurich. At the University of Zurich he was a favorite student of Professor Kundt whom he followed to University of Strabburg in 1873. Rontgen's original paper, "On A New Kind Of Rays", was published 50 days later after his discovery on 28 December 1895. On January 5th 1896, an Austrian newspaper reported Rontgen's discovery of a new type of radiation. Rontgen was awarded an honorary Doctor of Medicine degree from the University of Wurzburg after his discovery. He published a total of 3 papers on X-rays between 1895 and 1897.
Today, Rontgen is considered the father of diagnostic radiology, the medical specialty which uses imaging to diagnose disease.
