Bruckner Gyző

* Késmárk, November 1, 1900 – † Budapest, March 8, 1980 / organic chemist, ; pharmaceutical chemist, university professor, member of the Hungarian Academy of Sciences ; ; His father was a mathematics teacher for 25 years, then director of the Késmárk Lyceum, where his son also completed his secondary school studies. He earned a degree in chemical engineering from the József University of Technology in Budapest in 1925, and a doctorate in humanities from the Ferenc József University of Science in Szeged in 1928 for a work on physical chemistry (later he dealt exclusively with organic chemistry!). He taught in Szeged between 1926 and 1949. In 1926–1938 he was a member of the Institute of Chemistry of the Ferenc József University of Science and Technology, and He was an assistant professor and then a private teacher at the Institute of Organic Chemistry and Medicinal Chemistry, and from 1938 he was first a public extraordinary and then a full professor. From 1949 to 1970 he was a head professor at the ELTE University in Budapest. In the second half of the 1920s he was a visiting researcher at universities in Germany (Berlin–Charlottenburg) and Austria (Graz) for a few years. He mastered biochemical microanalytical methods from the Austrian Nobel Prize-winning chemist Fritz Pregl, which he successfully disseminated in Hungary. In Szeged he maintained good relations with the Nobel Prize-winning Albert Szent-Györgyi, who, among other things, discovered vitamin P. Győző Bruckner showed that this substance was actually a mixture of two flavono-glycosides. He achieved significant results primarily in the field of studying medicinal natural compounds, while discovering fundamental reaction mechanisms (e.g. reversible N–O-acyl migration, transfer of diene synthesis to aromatic systems). He is credited with the theoretical derivation and practical implementation of the synthesis of isoquinoline. One of his most significant discoveries was related to splenobacillus: in 1937, he determined that the pathogen owes its high resistance to a capsular substance containing a polypeptide built from a D-glutamic acid chain, which microorganisms capable of degrading or transforming L-amino acids cannot handle. From then on, Győző Bruckner primarily worked on peptide chemistry. At the turn of the 1950s and 1960s, under his leadership, the world's first artificial production of adrenocorticotropic hormone, produced in the pituitary gland, was achieved. He was a pioneering scientist, and his students later became professors and outstanding practitioners in their fields. Bruckner Győző received the Kossuth Prize twice (1949, 1955). He was a member of numerous Hungarian and foreign scientific societies. The Hungarian Academy of Sciences elected him a corresponding member in 1946 and a full member in 1949. His uncle of the same name – Bruckner Győző (1877–1962) – became known as a legal historian and a member of the Hungarian Academy of Sciences. His younger brother, Bruckner Zoltán (Késmárk, December 11, 1902 – Budapest, June 23, 1958) also became a chemical engineer and was one of the directors of the Hungarian rubber industry. As a prisoner of war in the Soviet Union from 1945 to 1950, he was involved in research into building materials and the development of soil improvement technologies. ; ; His main works: ; Organic Chemistry I-III., 1952–1981. ; ; &nbsp,
