Short Summary
Otto Hahn was a pioneering German chemist renowned for his work in radioactivity and radiochemistry. He is best known for the discovery of nuclear fission, a breakthrough that significantly impacted both scientific research and world history. His contributions to chemistry earned him the Nobel Prize in Chemistry in 1944. Hahn's work laid the groundwork for the development of nuclear energy and had profound implications during and after World War II.
Early Life & Education
Otto Hahn was born on March 8, 1879, in Frankfurt am Main, Germany, into a middle-class family. His father, Heinrich Hahn, was a successful businessman, and his mother was Charlotte Hahn. From a young age, Otto showed a keen interest in chemistry, conducting simple experiments in his home. He attended the University of Marburg and later the University of Munich, where he studied chemistry and earned his doctorate in 1901. Influenced by his professors and early exposure to scientific literature, he developed a strong foundation in the field of chemistry.
Career Highlights
Hahn's career began at the University College London under Sir William Ramsay, where he researched radioactivity. He then worked in Montreal with Ernest Rutherford, furthering his studies in radiochemistry. In 1907, he returned to Germany, joining the Kaiser Wilhelm Institute for Chemistry, where he spent most of his career. Hahn, along with his colleague Lise Meitner, discovered several new isotopes and ultimately achieved the groundbreaking discovery of nuclear fission in 1938. His work significantly advanced the understanding of atomic structure and radioactivity.
