Wilhelm ROntgen Wilhelm Conrad Rontgen
Wilhelm Conrad Röntgen (German pronunciation:[ˈvɪlhɛlm ˈʁœntɡən]; 27 March 1845 – 10 February 1923) was a Germanphysicist, who, on 8 November 1895, produced and detected electromagnetic radiation in a wavelength range today known as X-rays or Röntgen rays, an achievement that earned him the first Nobel Prize in Physics in 1901
Biography :
Röntgen was born in Lennep (which is today a borough of Remscheid) in Rhenish Prussia as the only child of a merchant and manufacturer of cloth. His mother was Charlotte Constanze Frowein of Amsterdam. In March 1848, the family moved to Apeldoornand Wilhelm was raised in the Netherlands. He received his early education at the boarding school, Institute of Martinus Herman van Doorn, in Apeldoorn. From 1861 to 1863, he attended the ambachtsschool in Utrecht. He was expelled for refusing to reveal the identity of a classmate guilty of drawing an unflattering portrait of one of the school's teachers. Not only was he expelled, he subsequently found that he could not gain admittance into any other Dutch or German gymnasium.[2]
In 1865, he tried to attend the University of Utrecht without having the necessary credentials required for a regular student. Upon hearing that he could enter the Federal Polytechnic Institute in Zurich (today known as the ETH Zurich), he passed its examinations, and began studies there as a student of mechanical engineering. In 1869, he graduated with a Ph.D. from the University of Zurich; once there, he became a favorite student of Professor August Kundt, whom he followed to the University of Strassburg in 1873.

Personal life:
Röntgen was married to Anna Bertha Ludwig (m. 1872, d. 1919) and had one child, Josephine Bertha Ludwig. Adopted at age 6, in 1887, she was the daughter of Anna's brotherRöntgen died on 10 February 1923 from carcinoma of the intestine It is not believed his carcinoma was a result of his work with ionizing radiation because of the brief time he spent on those investigations, and because he was one of the few pioneers in the field who used protective lead shields routinely. In keeping with his will, all his personal and scientific correspondence were destroyed upon his death
