Ruzicka, Leopold, Adolf Butenandt of Germany, of the 1939 Nobel Prize for Chemistry for his work on ringed molecules, terpenes (a class of hydrocarbons found in the essential oils of many plants), and sex hormones. Ruzicka's investigations of natural odoriferous compounds, begun in 1916, culminated in the discovery that the molecules of muskone and civetone, important to the perfume industry, contain rings of 15 and 17 carbon atoms, respectively. Before this discovery, rings with more than eight atoms had been unknown and indeed had been believed to be too unstable to exist. Ruzicka's discovery greatly expanded research on these compounds. He also showed that the carbon skeletons of terpenes and many other large organic molecules are constructed from multiple units of isoprene. In the mid-1930s Ruzicka discovered the molecular structure of several male sex hormones, notably testosterone and androsterone, and subsequently synthesized them.

FECS Millennium Project 100 Distinguished European Chemists 20th Century Ruzicka, Leopold Stephen Born: Vukovar (now Croatia), 1887 Died: Mammern (Switzerland), 1976 Ruzicka studied chemistry at the Technical University of Karlsruhe (Germany), where he received his doctorate under H. Staudinger (1910). After a professorship in Utrecht (The Netherlands) (1927-1929) he became professor of chemistry at the Swiss Federal Institut for Technology (ETH). His main work started in 1921. It involved: macrocyclic compounds, higher terpenes and steroids. He shared the Nobel Prize with Butenandt in 1939. His "biogenetic isoprene rule", which was pioneered by Wallach, became, in 1953, the crowning of his life.

home Register Bedlington Terrier Gartenorchideen ... Banner Genealogie Der Familienname Ruzicka Ruzicka 245/461 (sowie Ruzicska 10/17, Ruziczka 26/35, Ruzizka 11/15, Ruschitzka 33/78 und Ruzitschka 1/3) ist, ebenso wie das nicht ganz so häufige Ruzek 31/41, eine Verkleinerungsform von Ruze 4/6 Rose. Zwar ist die Ableitung von einem Hausnamen denkbar, aber die weite Verbreitung legt eher die Verwandtschaft mit dem weiblichen Vornamen Rosa (tschech. Roza 6/7) und Rosomil nahe. Davon allerdings kaum zu unterscheiden ist eine Herleitung aus einem der genannten Familiennamen in der Grundbedeutung Rose, was sich auf einen Rosengärtner beziehen kann, wie deutsche Belege seit dem 14 Jahrhundert zeigen.(Simek/Mikulasek: Kleines Lexikon der tschechischen Familiennamen in Österrreich,1995) Die Zahlen hinter den Namen geben vor dem Schrägstrich die Zahl der Telefonteilnehmer in Wien, hinter dem Schrägstrich die Zahl der Telefonteilnehmer in ganz Österreich, inklusive Wien an. Im Bezirk Beneschau in Tschechien, dem Ursprung der Familie Dr.Ruzicka, gibt es 22 Telefonteilnehmer mit dem Namen Ruzicka. Die Familie Dr.Ruzicka ab 1700

His family of craftsmen and farmers was of Czech German and Croatian origin and was the first Nobel Prize winning Croatian chemist. He holds eight honorary doctorates (4 Science Medicine , 1 Natural Sciences, 1 Law ), 7 prizes and medals, and 24 honorary memberships in chemical, biochemical, and other scientific societies. edit Education Osijek . He changed his original idea of becoming a priest and switched to studying technical disciplines. Chemistry was his choice, probably because he hoped to get a position at the newly opened sugar refinery built in Osijek. Due to the excessive hardship of everyday and political life, he left and chose the High Technical School in Karlsruhe in Germany . He was a good student in areas he liked and that he thought would be necessary and beneficial in future, which was organic chemistry . That is why his physical chemistry professor

Nobel Prize Winning Chemists Leopold Ruzicka The Nobel Prize for Chemistry 1939 Leopold Stephen Ruzicka was born on September 3, 1887, in Vukovar. His father, Stjepan Ruzicka, was a cooper; his mother's maiden name was Ljubica Sever. After the early death of his father in 1891, he returned with his mother to her birthplace, Osijek, on the Drava somewhat west of its junction with the Danube. There he attended the primary school and the classical gymnasium where the Croatian language was used. He wanted to study at the Zurich Polytechnic Institute but found to his dismay that an entrance examination was required not only in chemistry but also in "descriptive geometry". He chose the Technische Hochshule at Karlsrohe, where he began his chemical studies in 1906. After two years of research work Ruzicka was a "Dipl. Ing", and two weeks later "Dr. Ing". Professor Staudinger appointed him as his assistant, and they together entered the quite unexplored field of the active constituents-named by them pyrethrins-of Dalmatian insect powder, a plant product, toxic to insects and other cold-blooded animals. They thus opened a new chapter of alicyclic chemistry, which was then as unfamiliar to Ruzicka as it was to Staudinger. He was awarded the Nobel Prize for Chemistry in 1939 "for his work on polymethylenes and higher terpenes".
