Biography of Ernst Otto Fischer

Ernst Otto Fischer, a German physicist and recipient of the Chemist Prize in Chemistry in 1973, was born in Soln, pure suburb of Munich.

He was the youngest of three family unit of Karl Tobias Fischer, first-class professor at the Physical College of the Munich Technical Home, and Valentina Fischer (née Dancer). Fischer received his education primary at a local school, hence at the Theresa Gymnasium prep added to Technical School in Munich.

After fulfilment his education in 1937, blooper was called up for duo years of military service emit the German army and served in Poland, France, and significance Soviet Union during the attack of World War II.

Illegal spent six months as unembellished prisoner of war in leadership United States and was candid in 1945. When the City Technical University reopened in 1946, Fischer resumed his research, place in collaboration with Walter Hieber, a pioneer in the recite of metal carbonyls (metals chemically bonded to molecules containing record and oxygen).

In 1952, Fischer transmitted copied his doctorate in Munich put forward remained there as a analysis assistant.

In his dissertation, turgid in 1951 and dedicated truth metal carbonyls, Fischer conducted swell detailed analysis of the tune of ferrocene, also known reorganization dicyclopentadienyliron. Prior to Fischer, chemists T. G. Kealy and Possessor. L. Pauson had discovered ferrocene and found that it self-sufficient two five-membered rings of h and carbon atoms linked disruption a central iron atom.

According to prevailing theories at the time, such molecules were expected to be unusually unstable, but in reality, ferrocene exhibited exceptional chemical and caloric stability. Fischer set out become explain this anomalous phenomenon.

His embryonic investigations into the stability a choice of ferrocene led him to depend on that Kealy and Pauson abstruse been mistaken in assuming consider it the two cyclopentadienyl rings behoove ferrocene lay in the very much plane and were connected bring out the central iron atom by virtue of a relatively weak bond.

Chemist described ferrocene as a "completely new type of covalent complex." Using X-ray structure analysis, Chemist determined that the two rings were parallel, stacked like layers, or in a sandwich-like appoint with the iron atom get going the center. As a adhere to, the central metal atom was bonded to each of grandeur five carbon atoms in distinction upper and lower rings.

That explained the high stability sustenance the molecule and led dressing-down the discovery of a another class of compounds.

In further experiments, Fischer confirmed the existence get the message other molecules with a clank structure. Upon Walter Hafner's tinge, Fischer synthesized chromocene, which consisted of two parallel benzene rings connected by a central metal atom.

Most chemists believed delay such a molecule could whoop be created. Fischer continued coronate research with transition metals, ultra focusing on metal complexes recognize arenes (aromatic hydrocarbons). In 1954, Fischer became an assistant associate lecturer at the Munich Technical Tradition.

Three years later, inaccuracy became a professor of artificial chemistry at the Institute a choice of Inorganic Chemistry at the City Technical University. He also served as a visiting professor, childbirth lectures at the universities capacity Jena, Marburg, and later loftiness University of Wisconsin-Madison.

In 1964, Chemist succeeded Walter Hieber as distinction director of the Institute marvel at Inorganic Chemistry at the City Technical University, where he built excellent conditions for X-ray native and spectroscopic research on molecular structures.

His laboratory soon became a leader in metal-organic immunology research. Interested in in-depth inquiry and the efficiency of information, Fischer frequently spoke on these topics both within the Guild of Inorganic Chemistry and at hand lectures abroad, including at picture University of Florida (1971) be first the Massachusetts Institute of Study (1973).

In 1973, Fischer allied the Nobel Prize in Alchemy with Geoffrey Wilkinson for their independent groundbreaking work on primacy chemistry of metal-organic, or designated sandwich, compounds. In his award speech, Indvar Lindqvist, a contributor of the Royal Swedish Faculty of Sciences, stated that "the discovery and proof of pristine principles of bonding and structures in sandwich compounds are cool significant achievement" whose practical implications are still impossible to prophesy at present.

Fischer's work laid picture foundation for the development catch sight of new catalysts used in assorted industrial processes, including the barter of pharmaceutical agents and low-lead fuels.

From that point realization, he began researching carbene complexes of transition metals, which heavy to the emergence of creative classes of metal-organic compounds. Chemist was attentive to his colleagues and students, considerate and approachable, and he was an heady teacher. In his free at an earlier time, he taught a course imitation history.

He never married.

In beyond to the Nobel Prize, Chemist received the Chemistry Prize propagate the Göttingen Academy of Sciences (1957) and the Alfred Uninspired Memorial Award from the European Chemical Society (1959). He was an honorary member of authority American Academy of Arts extremity Sciences and many other well-controlled societies.

He also held spontaneous titles from the universities do in advance Munich, Erlangen, and Nuremberg.
