Biography
Born September 16, 1882 in Basel in the family of the pharmacist Dr. Friedrich Geiger and his wife Elisabeth Caroline Geiger (née Knapp ).
He studied physics, mathematics, astronomy and chemistry in Basel . After three semesters, he moved to Berlin , and then to Heidelberg , where he studied for one semester. He graduated in Göttingen, where he conducted experimental work at the Institute of Mathematical Physics, together with Professor Waldemar Voigt . Here he continued to engage in atomic physics and spectroscopy.
On January 1, 1913, the Göttingen Academy of Sciences invited Geiger to work as an observer astronomer in geophysics and meteorology at the Samoa Observatory for one year, where he stayed longer due to the outbreak of World War I. At that time, the Samoan Islands in the South Pacific were a German colony called protectorate. In March 1915, he left the island and returned to Basel. Since he could not get the post of geophysicist, Geiger completely changed his profession, becoming a manager at his brother's pharmaceutical factory.
Together with Emil Wiechert, Geiger first used the method, which today is known as the Wiechert-Herglotz (or Herglotz-Wiechert) method, to determine the velocity structure in the bowels of the Earth.
He died on November 26, 1966 in Basel.
He was married since 1907 to Else Flügel , the family had two sons (born in 1908 and 1909).
