		Ruzicka was interested in the large ring ketones civetone and muscone because of their musk odor, and showed through degradation and synthesis that they had 17- and 15-membered carbon rings.
		In his work on terpenes, Ruzicka made extensive use of the isoprene rule, first formulated by Otto Wallach in 1887 (see portrait) but largely ignored until Ruzicka recognized its general significance.
		Ruzicka was born in Croatia (though he published under Leopold, his given name was Lavoslav) but, after studies in Germany he moved to Switzerland where he spent most of his career at the Swiss Federal Institute of Technology (ETH).

		He enrolled at the Federal Institute of Technology in Zürich as a chemical engineer, and by the time he graduated he was fascinated with the work being done on steroid hormones in the laboratories of Leopold Ruzicka and Thaddeus Reichstein.
		Ruzicka was convinced that there was a structural relationship among the various terpenes based on a common building block (now known as the isoprene unit).
		In the hope of finding a synthetic principle for the construction of this class of compounds, Ruzicka put his students to work on determining structures of and synthesizing many of the terpenes.

		The care with which the appointments of that era were made is demonstrated by the fact that, of the 4 professors appointed between 1893 and 1929, 3 received the Nobel Prize in Chemistry for work done largely at the ETH (R. Willstätter, R. Kuhn, H. Staudinger).
		The next two professors, Leopold Ruzicka and Vladimir Prelog, both also subsequent Nobel Laureates, were born in Vukovar and Sarajevo, respectively.
		In accord with the rising international prominence of Chemistry at the ETH, Ruzicka and Prelog stayed at the ETH for 28 and 25 years, respectively.

		Almost simultaneously in Switzerland, the Slav chemist Leopold Ruzicka secured a patent for T-production by the same means.

		• You learn how Ruzicka, another Croat and a leader in the structural determination and synthesis of hormones, brought Prelog to safe haven in Switzerland during World War II, and how Prelog succeeded Ruzicka as director of organic chemistry at the ETH, one of the world's most respected laboratories.
		And then the President took Ruzicka and said, "Professor Ruzicka, you shouldn't say such things before the public.
		Prelog seems to toy with the alternative of 50 years (as a very young child Ruzicka may have been better behaved).
