Hans Geiger was born on September 30, 1882, in Neustadt an der ​Weinstraße, Germany. He studied physics at the University of Berlin, where ​he was influenced by prominent physicists like Max Planck and Albert ​Einstein.

Key Experiment & Experiment

Geiger is best known for developing the Geiger counter, an instrument for ​detecting and measuring ionizing radiation. In 1909, he collaborated with ​Ernest Marsden on the gold foil experiment, which provided crucial evidence ​for the existence of the atomic nucleus. Geiger's precise measurements and ​techniques during this experiment helped confirm Rutherford’s model of the ​atom.

Later Life

In his later career, Geiger focused on research related to nuclear ​physics and radiation detection, contributing significantly to the field. ​He held academic positions in various institutions, including the ​University of Berlin and the University of Kiel.

Death

Geiger passed away on September 24, 1975, in Kiel, Germany. His ​inventions and research greatly advanced the understanding of atomic ​structure and radiation, leaving a lasting legacy in nuclear physics.
