Who is that - the solution

The Nobel Prize winner who wanted mankind to benefit from his discovery is Wilhelm Conrad Röntgen.



Wilhelm Conrad Röntgen (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 Röntgen rays, an achievement that earned him the first Nobel Prize in Physics in 1901.

Following transliteration conventions for characters accented by an umlaut, "Röntgen" in English is spelled "Roentgen", and that is the usual rendering found in English-language scientific and medical references.
