Biography of Wilhelm Conrad Rontgen

Wilhelm Conrad Rontgen is the famous Inventor of X-rays. He was born on 27 of March 1845 in Lennep, Germany. Wilhelm Rontgen was a German Physicist.  His family migrates to Netherlands when he was just 3 years old where he started boarding school in Institute of Martinus Herman Van Doorn. Primarily, Wilhelm Conrad Rontgen is famous for the discovery of X-rays.


In 1862, Wilhelm Conrad Rontgen was expelled unfairly from the technical school of Utrecht. The reason behind expelling Rontgen was that he made caricature of his teacher which is actually done by someone else.  Right after 3 years, in 1865 he again took admission in Utrecht for studying Physics. He had no credential for a regular student so on hearing that he could pass the examination for Polytechnic at Zurich.  He passed the examination and starting studies of mechanical Engineering.


He graduated in Ph.D. at University of Zurich and appointed as an assistant of Kundth, Professor of Rontgen and in the same year Rontgen went with Kundth in Wurzburg. In 1874, he appointed as a Lecturer in University of Strasbourg but in next year he joined the University of Hoenhem as a Professor of Academy in Agriculture. In 1900, Wilhelm Conrad Rontgen accepted the offer for Chair of Physics in the University of Munich on special request of Bavarian Government where he remained attached for the rest of his life.

Discovery of X-rays

During 1895 Wilhelm Conrad Rontgen was already working on the effects of cathode rays before determining the X-rays. His experiment was involved in passing of electric current through gases at enormously low pressure while he was experimenting on November 8, 1895 he observed that some specific rays were emitted during passing the current through discharge tube. He did his experiment in a dark room with a well-covered discharge tube resulting in the emission of rays which brightened a barium platinocyanide covered screen. The screen became glowing even though it was positioned in the path of the rays and 2 meters away from the discharge tube.

He continuously involved in experiments by using the photographic plate in order to capture the pictures of objects of random thickness placed in the path of rays. He generated his ‘roentgenogram” by developing the image of wife’s hand. Wilhelm analyzes his wife’s bone, wedding ring and flesh by variable transparency.

What is X-rays?

X-rays are the electromagnetic waves which are used for medical purposes. X radiations (X-rays) have highly short wavelength and high frequency with the wavelengths of range from 10-8 to 10-12 meter and corresponding frequencies are about from 1016 to 1020 hertz.

Noble Prize

In 1901, Wilhelm Conrad Rontgen received a Noble prize for his incredible discovery which is considered beneficial for the mankind in future.

Purpose of X-rays

X rays are beneficial in identifying the abnormalities which is present in the body. No doubt they are painless, non-invasive way to help in detecting the problems, for instance tumors, broken bones, limbs and cervical problems, dental decay, and the presence of foreign bodies etc.
Frequency of X-rays is higher than the UV rays which is commonly called as Ultra Violet Rays.

Deprivation from a Great Person

In February 10, 1923 Wilhelm Conrad Rontgen left the world and the nation deprived from an intelligent Physicist. He had done a great job for the nation by providing the X-rays which is till now helpful in diagnosing the diseases from mild to severe.  His other colleague really appreciates his outstanding and remarkable work and the entire world known his name for the discovering of X-rays in the year 1895.
