Hans Geiger

Hans Geiger was a German physicist best known for his contributions to atomic physics, particularly the development of the Geiger counter, an instrument used to detect and measure ionizing radiation. His work in the early 20th century included experiments that provided evidence for the existence of the atomic nucleus, alongside Ernest Rutherford. Geiger's research helped advance our understanding of atomic structure, paving the way for modern physics and related fields. The Geiger counter remains essential in fields like radiation safety, nuclear industry, and medical applications, highlighting Geiger's lasting impact on science and technology.
