Fritz-Haber-Institut
The Fritz Haber Institute of the Max Planck Society (FHI) is a science research institute located at the heart of the academic district of Dahlem, in Berlin, Germany. The original Kaiser Wilhelm Institute for Physical Chemistry and Electrochemistry, founded in 1911, was incorporated into the Max Planck Society and simultaneously renamed for its first director, Fritz Haber, in 1953. The research topics covered throughout the history of the institute include chemical kinetics and reaction dynamics, colloid chemistry, atomic physics, spectroscopy, surface chemistry and surface physics, chemical physics and molecular physics, theoretical chemistry, and materials science. During World War I and World War II, the research of the institute was directed towards Germany's military needs. To the illustrious past members of the Institute belong Herbert Freundlich, James Franck, Paul Friedlander, Rudolf Ladenburg, Michael Polanyi, Eugene Wigner, Ladislaus Farkas, Hartmut Kallmann, ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Robert Havemann
Robert Havemann (; 11 March 1910 – 9 April 1982) was an East German chemist and dissident. Life and career He studied chemistry in Berlin and Munich from 1929 to 1933, and then later received a doctorate in physical chemistry from the Kaiser Wilhelm Institute. Havemann joined the Communist Party of Germany (KPD) in 1932 and was one of the founders of the resistance group, European Union. It was in connection with this group that he was arrested by the Gestapo in 1943. He received a death sentence, but his execution was continually postponed because of the intervention of former colleagues, who insisted that Havemann was as important due to his work on chemical weapons and that he was still needed to explain the research. His execution was postponed so many times, he was able to survive until the Brandenburg-Görden Prison was liberated by the Red Army.Bernd Florath.

Otto Hahn
Otto Hahn (; 8 March 1879 – 28 July 1968) was a German chemist who was a pioneer in the fields of radioactivity and radiochemistry. He is referred to as the father of nuclear chemistry and father of nuclear fission. Hahn and Lise Meitner discovered radioactive isotopes of radium, thorium, protactinium and uranium. He also discovered the phenomena of atomic recoil and nuclear isomerism, and pioneered rubidium–strontium dating. In 1938, Hahn, Lise Meitner and Fritz Strassmann discovered nuclear fission, for which Hahn received the 1944 Nobel Prize for Chemistry. Nuclear fission was the basis for nuclear reactors and nuclear weapons. A graduate of the University of Marburg, Hahn studied under Sir William Ramsay at University College London and at McGill University in Montreal under Ernest Rutherford, where he discovered several new radioactive isotopes. He returned to Germany in 1906; Emil Fischer placed a former woodworking shop in the basement of the Chemical I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hartmut Kallmann
Harmut Kallmann (5 February 1896 – 11 June 1978) was a German physicist. He is known for his work on the scintillation counter for the detection of gamma rays. Biography - Career Kallmann was born in Berlin in a Jewish family. He studied at the University of Göttingen and wrote his dissertation under Max Planck, completing it in 1920. After this he worked at the Kaiser Wilhelm Institute for Physical Chemistry and Electrochemistry. As a post-doctoral researcher he worked with Fritz Haber and Fritz London. In 1933 he was dismissed from the institute due to his ''non-Aryan'' Jewish descent. The companies IG Farben and AEG provided him a research lab to continue his work with some restrictions. Kallmann built the world's first organic scintillator in Berlin. Thermo Electron corporation (now Thermo Fisher Scientific) credited Kallmann and Broser with pioneering modern day scintillation counting by combining a scintillating material with a photomultiplier, as a means of impr ...

Eugene Wigner
Eugene Paul "E. P." Wigner ( hu, Wigner Jenő Pál, ; November 17, 1902 – January 1, 1995) was a Hungarian-American theoretical physicist who also contributed to mathematical physics. He received the Nobel Prize in Physics in 1963 "for his contributions to the theory of the atomic nucleus and the elementary particles, particularly through the discovery and application of fundamental symmetry principles". A graduate of the Technical University of Berlin, Wigner worked as an assistant to Karl Weissenberg and Richard Becker at the Kaiser Wilhelm Institute in Berlin, and David Hilbert at the University of Göttingen. Wigner and Hermann Weyl were responsible for introducing group theory into physics, particularly the theory of symmetry in physics. Along the way he performed ground-breaking work in pure mathematics, in which he authored a number of mathematical theorems. In particular, Wigner's theorem is a cornerstone in the mathematical formulation of quantum mechanics. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Michael Polanyi
Michael Polanyi (; hu, Polányi Mihály; 11 March 1891 – 22 February 1976) was a Hungarian-British polymath, who made important theoretical contributions to physical chemistry, economics, and philosophy. He argued that positivism supplies an imperfect account of knowing as no observer is perfectly impartial. His wide-ranging research in physical science included chemical kinetics, x-ray diffraction, and adsorption of gases. He pioneered the theory of fibre diffraction analysis in 1921, and the dislocation theory of plastic deformation of ductile metals and other materials in 1934. He immigrated to Germany, in 1926 becoming a chemistry professor at the Kaiser Wilhelm Institute in Berlin, and then in 1933 to England, becoming first a chemistry professor, and then a social sciences professor at the University of Manchester. Two of his pupils, and his son John Charles Polanyi won Nobel Prizes in Chemistry. In 1944 Polanyi was elected to the Royal Society. The contribution ...

He emigrated from Germany as early as 1932 and became a Brackett Research Professor at Princeton University. When the wave of German emigration began in 1933, he was the principal coordinator for job placement of exiled physicists in the United States. Albert Einstein gave the eulogy at Rudolf's funeral. He and his wife Elsa had three children, Margarethe, Kurt, and Eva. Kurt had two children, Toni and Nils Ladenburg.

Paul Friedländer (29 August 1857 in Königsberg – 4 September 1923 in Darmstadt) was a German chemist best known for his research on derivates of indigo (for example thioindigo) and isolation of Tyrian purple from ''Murex brandaris''. Life and work Paul Friedländer was born as son of Ludwig Friedländer in Königsberg in 1857. The chemist Carl Gräbe was a regular guest of his father; thus after finishing the gymnasium, Friedländer studied chemistry in Königsberg in the laboratories of Gräbe.
