Johannes Wilhelm Geiger (/ ˈɡaɪɡər /; German: [ˈɡaɪɡɐ]; 30 September 1882 – 24 September 1945) was a German physicist. He is known as the inventor of the Geiger counter, a device used to detect ionizing radiation, and for carrying out the Rutherford scattering experiments, which led to the discovery of the atomic nucleus.

Hans Geiger (born September 30, 1882, Neustadt an der Haardt, Germany—died September 24, 1945, Potsdam) was a German physicist who introduced the first successful detector (the Geiger counter) of individual alpha particles and other ionizing radiations.

The German physicist Hans Wilhelm Geiger is best known as the inventor of the Geiger counter to measure radiation. In 1908, Geiger introduced the first successful detector of individual alpha particles. Later versions of this counter were able to count beta …

Hans Geiger was a German nuclear physicist (a person who studies the inner core of the atom) best known for his invention of the Geiger counter, a device used for detecting and counting atomic particles, and for his work in nuclear physics with Ernest Rutherford (1871–1937).

Nuclear physicist Hans Geiger, whose surname is known all over the world 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.

Feb 2, 2024 · Hans Geiger (1882–1945) was a German physicist renowned for his contributions to the field of nuclear physics and, notably, for his invention of the Geiger-Müller counter, an essential tool for detecting and measuring ionizing radiation.

Hans Geiger (1882-1945) was director of the Physics Institute of Königlich Technische Hochschule zu Berlin. Together with his colleague Walter Müller, he invented the Geiger-Müller counter used to measure radioactive particles and determine their energy level.

May 18, 2018 · Hans Geiger was a German nuclear physicist best known for his invention of the Geiger counter, a device used for counting atomic particles, and for his pioneering work in nuclear physics with Ernest Rutherford.

Johannes Wilhelm "Hans" Geiger (30 September 1882 – 24 September 1945) was a German physicist. He is perhaps best known as the co-inventor of the detector component of the Geiger counter and for the Geiger–Marsden experiment which discovered the atomic nucleus .

German nuclear physicist who developed various instruments and techniques for measuring charged nuclear particles—the most famous of which is the Geiger-Müller counter, commonly referred to as the Geiger counter. Geiger invented an alpha-particle detector in 1908 that allowed him and Ernst Rutherford to show alpha-particles to be helium nuclei.
