About Wilhelm Conrad Roentgen

The following text is largely based on the publication
"Important Personalities at the University of Giessen", page 12

Wilhelm Conrad Roentgen was a full professor of physics at the University of Giessen from 1879 to 1888. Later he taught as a professor at the universities in Würzburg and Munich. He was the first to receive the Nobel Prize in Physics in 1901 for the discovery of x-rays at the Physics Institute of the University of Würzburg on November 8, 1895. In German, his discovery is named Röntgenstrahlen after him.

During his time in Giessen, Roentgen brought about the relocation of the Institute of Physics from Frankfurter Strasse to the new main university building. He published about twenty scientific papers during this time, including work on the ‘x-ray tone’, in which he showed that gases absorb heat rays, and work on the detection of the magnetic field produced by a displacement current (‘x-ray current’).

Roentgen Prize and Roentgen Sculpture

In Roentgen’s honor, numerous honors and prizes are still awarded throughout Germany today such as the Roentgen Prize of the University of Giessen for outstanding work on basic research in radiation physics, photonics, and radiation biology. Moreover, he is commended by monuments in many German cities, including Giessen with the Roentgen Monument on Südanlage.

Based on Erich F. Reuter’s design for the Roentgen Monument in Giessen, a Roentgen sculpture was created for the Roentgen anniversary year 2020, which will accompany the ceremonial awarding of the Roentgen Prize at JLU in the future and can thus be seen as a visible sign of this high academic honor. The Roentgen sculpture can also be seen on the announcement poster.
