In this peaceful corner of Potsdam, marked by a simple tombstone, lies a giant of science. Hans Geiger. His name might not ring a bell immediately, but his invention probably does: the Geiger counter. Yes, right here rests the man who gave us the ability to detect radiation. Geiger was born in Germany in 1882. He initially embarked on a journey into the heart of the atom. His work with Ernest Rutherford in Manchester led to the groundbreaking Geiger-Marsden experiment, also known as the gold foil experiment. This experiment unveiled the existence of the atomic nucleus, a discovery that revolutionized our understanding of matter itself. Later, in 1928, Geiger, along with his student Walther Müller, perfected the device that would become his legacy: the Geiger-Müller counter. This invention, a tool to measure radiation, went on to become essential in various fields, from physics research to medical treatments and even disaster management. Think about Chernobyl or Fukushima. The Geiger counter played, and still plays, a critical role in monitoring radiation levels and ensuring safety. As you stand here, in the presence of Geiger’s final resting place, remember this man. His work transcended the boundaries of the laboratory, leaving an indelible mark on science and safety across the globe.
