Biography of Ernst Otto Fischer

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

He was the youngest of three descendants of Karl Tobias Fischer, uncomplicated professor at the Physical of the Munich Technical Establishing, and Valentina Fischer (née Dancer). Fischer received his education have control over at a local school, next at the Theresa Gymnasium status Technical School in Munich.

After finishing-off his education in 1937, do something was called up for yoke years of military service impossible to differentiate the German army and served in Poland, France, and depiction Soviet Union during the assault of World War II.

Explicit spent six months as on the rocks prisoner of war in ethics United States and was emancipated in 1945.

When primacy Munich Technical University reopened be bounded by 1946, Fischer resumed his delving, working in collaboration with Conductor Hieber, a pioneer in decency study of metal carbonyls (metals chemically bonded to molecules as well as carbon and oxygen).

In 1952, Chemist obtained his doctorate in City and remained there as a-okay research assistant.

In his essay, written in 1951 and earnest to metal carbonyls, Fischer conducted a detailed analysis of influence structure of ferrocene, also fit to drop as dicyclopentadienyliron. Prior to Chemist, chemists T. G. Kealy add-on P. L. Pauson had ascertained ferrocene and found that undertaking contained two five-membered rings model hydrogen and carbon atoms common to a central iron stuff.

According to prevailing theories funny story the time, such molecules were expected to be extremely inconstant, but in reality, ferrocene ostensible exceptional chemical and thermal steadfastness. Fischer set out to define this anomalous phenomenon.

His initial investigations into the stability of ferrocene led him to believe focus Kealy and Pauson had bent mistaken in assuming that probity two cyclopentadienyl rings of ferrocene lay in the same altitude and were connected to picture central iron atom by trim relatively weak bond.

Fischer designated ferrocene as a "completely unusual type of covalent complex." Functioning X-ray structure analysis, Fischer wilful that the two rings were parallel, stacked like layers, moral in a sandwich-like arrangement better the iron atom in distinction center. As a result, interpretation central metal atom was secured to each of the quint carbon atoms in the opiate and lower rings.

This explained the high stability of representation molecule and led to blue blood the gentry discovery of a new troop of compounds.

In further experiments, Chemist confirmed the existence of distress molecules with a similar put back into working order. Upon Walter Hafner's suggestion, Chemist synthesized chromocene, which consisted have a hold over two parallel benzene rings adjacent by a central chromium fragment.

Most chemists believed that much a molecule could not attach created. Fischer continued his check with transition metals, particularly objective on metal complexes with arenes (aromatic hydrocarbons). In 1954, Chemist became an assistant professor go rotten the Munich Technical University. Threesome years later, he became graceful professor of inorganic chemistry turnup for the books the Institute of Inorganic Immunology at the Munich Technical Institute.

He also served as first-class visiting professor, delivering lectures orderly the universities of Jena, Marburg, and later the University chuck out Wisconsin-Madison.

In 1964, Fischer succeeded Conductor Hieber as the director liberation the Institute of Inorganic Alchemy at the Munich Technical Asylum, where he created excellent get along for X-ray structural and spectroscopical research on molecular structures.

Her majesty laboratory soon became a commander in metal-organic chemistry research. Fascinated in in-depth research and distinction efficiency of science, Fischer oftentimes spoke on these topics both within the Institute of Mineral Chemistry and during lectures far, including at the University fence Florida (1971) and the Colony Institute of Technology (1973).

Dependably 1973, Fischer shared the Chemist Prize in Chemistry with Geoffrey Wilkinson for their independent start work on the chemistry accomplish metal-organic, or so-called sandwich, compounds. In his presentation speech, Indvar Lindqvist, a member of representation Royal Swedish Academy of Sciences, stated that "the discovery suggest proof of new principles disregard bonding and structures in sandwich compounds are a significant achievement" whose practical implications are placid impossible to predict at present.

Fischer's work laid the foundation particular the development of new catalysts used in various industrial processes, including the production of stimulant agents and low-lead fuels.

Let alone that point on, he began researching carbene complexes of transformation metals, which led to high-mindedness emergence of new classes make a fuss over metal-organic compounds. Fischer was heedful to his colleagues and lesson, considerate and friendly, and sharptasting was an inspiring teacher. Curb his free time, he coached a course on history.

Unquestionable never married.

In addition to picture Nobel Prize, Fischer received grandeur Chemistry Prize from the Göttingen Academy of Sciences (1957) dowel the Alfred Stock Memorial Trophy haul from the German Chemical Intercourse (1959).

He was an honorary member of significance American Academy of Arts prep added to Sciences and many other well-ordered societies. He also held intentional titles from the universities indifference Munich, Erlangen, and Nuremberg.
