Otto Hahn (1879–1968) was a German chemist who was a pioneer in the field of radiochemistry. He is referred to as the father of nuclear chemistry. Working with Lise Meitner at the Kaiser Wilhelm Institute for Chemistry in the building that now bears their names, they discovered isotopes of the radioactive elements radium, thorium, protactinium and uranium. He also discovered the phenomena of atomic recoil and nuclear isomerism, and pioneered rubidium–strontium dating. In 1938, Hahn, Meitner, Otto Robert Frisch and Fritz Strassmann discovered nuclear fission, for which Hahn alone was awarded the 1944 Nobel Prize in Chemistry. He worked on the German nuclear program during World War II and at the end of the war he was arrested by the Allied forces and detained in Farm Hall. After the war, he became the founding president of the Max Planck Society and one of the most influential and respected citizens of post-war West Germany. (Full article...)
