Johannes Wihlem Geiger (Neustadt year der Weinstraße 1882 - Potsdam 1945), is a German Physicien which invented with Walther Müller the Geiger counter in 1928, meter of which he imagines the principle as of 1913. The Royal Society decrees to him the Médaille Hughes in 1928.

Geiger studies the Physique and the Mathématiques with Erlangen, where it obtains its doctorate in 1906. Starting from 1907, it works as assistant of Ernest Rutherford with the Université of Manchester, where it discovers with John Mitchell Nuttall the Loi of Geiger-Nuttal and carries out experiments which lead Rutherford to its atomic model. In 1908, it gives the proof of the statistical nature of the radioactive decays.

In 1912, it works with the German National institute of science and technology with Berlin, where it sets up a laboratory of study of the Radioactivité. It that it starts to develop a meter, is helped there by James Chadwick. Its research at the German National institute of Science and Technologie is stopped until in 1919 by the First World War. It is named professor with the Université of Berlin in 1924 following its studies to the measure of the radiations alpha.

It leaves Berlin for Kiel in 1925. It is there that it develops the Geiger counter with a student of doctorate, Walther Müller. It is named with Tübingen in 1929, then again with Berlin starting from 1936 where he is director of the institute of physics. It is made member of the Académie of Berlin in November 1936.

He was also member of the Uranverein (club of uranium) in the Nazi Germany, made up German physicists who tried without success to develop a atomic bomb during the Second world war.

Its honesty towards the Nazi party leads it to denounce his/her Jewish colleagues, of which some had previously helped it in its research.
