Hans Fisher Biography
The Nobel Prize in Chemistry, the German chemist Hans Fisher was born in Hehst-on-Maine in the family of Anna Fisher in the girlishness of Herdegen and Eigen Fisher, a chemist in the specialty and director of the factory and the company "Calle" for the production of dyes. After graduating from elementary school in Stuttgart, F. studied chemistry and medicine at the University of Lausanne; He continued his studies at the University of Marburg, where in the city after medical practice in the 2nd medical clinic in Munich F.
here he studied the complex structures of sugars and peptides of complexes, partially consisting of amino acids-fundamental compounds of living organisms. Having returned to G. Although many chemists tried to determine the structure of these two compounds and thus determine the nature of their relationship, the problem was too complicated. In G. three years later, he was a professor of medical chemistry at the University of Innsbruck.
The deprivations caused by the beginning of the First World War have greatly complicated experimental research. At the end of the war, he goes to the University of Vienna as a professor of organic chemistry, and in the city In Munich, F. is like other complex compounds, these pigments contain combinations of simpler compounds. One of these compounds, pyrrol, consists of four carbon atoms and one nitrogen atom connected to the ring.
When four pyrrhous structures are connected into a closed ring, a substance called porphyrin is formed.
At that time, it was believed that Porphyrin is the basis of all natural pigments, including bilirubin and hemin. In fact, however, each pigment has certain deputies and, in addition, specific regrouping of porphyrin groups. Only one hemin molecule, for example, contains 76 atoms. For such a large molecule, the laws of chemical combinations allow you to calculate all structure or isomers, each of which can have completely different chemical properties.
Despite the complexity of the subject, a significant number of studies have already been conducted on natural pigments. In his works by F. his ultimate goal was to understand the structure of hemin, a bilirubin which, as he believed, is formed when the hemin and herbal green pigment of chlorophyll, which was, in his opinion, is similar to hemoglobin. In the process of work by F., in his speech at the presentation of H.
Sederbaum, a member of the Swedish Royal Academy of Sciences, he called F. as a fanatical researcher, F. Dematev from grief after the almost complete destruction of his institute as a result of bombing by military aviation, he in the city after his death continued his work with chlorophyll and in the city of children did not have. Although chemical studies were the main thing of his life, he also liked the ascent to the mountains and skiing.
A demanding teacher, he felt a great responsibility for his students and helped them in every way. In addition to the Nobel Prize, F. he was an honorary doctor of Harvard University. Nobel laureates: Encyclopedia: Per. Wilson Company, Date of Publication:.
