Pronunciation: [ˈɒtə͡ʊ hˈɑːn] (IPA) 
Otto Hahn is a German chemist who was known for his pioneering work in the field of nuclear chemistry. The correct spelling of his name is "ˈɔto ˈhaːn" in IPA phonetic transcription. The first part of his name, "Otto," is pronounced with the "o" sound as in "boat" and the "t" sound is aspirated. The second part, "Hahn," has a long "a" as in "father" followed by the "h" sound, which represents an aspirated "h" in German.
Otto Hahn (1879-1968) was a German chemist and pioneer in the field of nuclear chemistry. He is best known for his discovery of nuclear fission, which revolutionized the understanding of atomic structure and led to the development of atomic energy.
Hahn's groundbreaking research on radioactivity and the behavior of radioactive isotopes laid the foundation for his eventual discovery of nuclear fission. In 1938, together with Fritz Strassmann, Hahn successfully demonstrated that bombarding uranium atoms with neutrons could cause them to split into lighter elements, releasing an immense amount of energy in the process. This breakthrough discovery proved the existence of nuclear fission and its potential as a powerful source of energy.
Otto Hahn received numerous accolades for his contributions to science, including the Nobel Prize in Chemistry in 1944, which he was awarded for his discovery of nuclear fission. This critically important insight paved the way for further research and development in atomic energy, nuclear weapons, and nuclear medicine.
Hahn also played a crucial role in advocating for the peaceful use of nuclear energy and actively opposed its deployment for military purposes. His scientific achievements and moral stance continue to inspire generations of scientists, and his name remains synonymous with the fundamental understanding of nuclear processes.
The word "Otto Hahn" is not derived from any specific etymology. It is the name of a German chemist and pioneer in the field of radiochemistry, Otto Hahn (1879-1968).
