Nuclear physicist Hans Geiger, whose surname is known the world over for his invention of the radioactivity measuring device known as the Geiger counter, was born Johannes Wilhelm Geiger in Neustadt-an-der-Haardt, Germany, on September 30, 1882.
Geiger studied physics at the University of Munich and went on to complete his doctoral degree in the subject at the University of Erlangen in 1906.
Geiger was also involved in a number of experiments that would lead to Rutherford’s breakthrough theory of the atom, which declared that the nucleus occupies a very small volume at the center of every atom.
