Konrad Bloch receives one half of the Nobel Prize in Physiology or Medicine along with Feodor Lynen "for their discoveries concerning the mechanism and regulation of the cholesterol and fatty acid metabolism".

Konrad Bloch enters Munich Technical University. Thanks to Hans Fischer, he develops a great interest for organic chemistry, particularly for the structure of natural products. He attends also the Sessions of the Münchener Chemische Gesellschaft and he hears great organic chemists as Adolph Windaus, Heinrich Wieland and Rudolf Willstätter reporting their researches on steroids, porphyrins and enzymes.

After retirement at Harvard in 1982, Konrad Bloch serves between 1986 and 1989 as the Mack and Effie Campbell Tyner Eminent Scholar Chair in the College of Human Sciences at Florida State University.

Konrad Bloch is appointed Assistant Professor of biochemistry at University of Chicago in the department headed by E. A. Evans Jr. Later Bloch becomes an Associate Professor (1948) and Professor (1950). In Chicago he continues working on cholesterol and he also works with J. Snoke on the enzymatic synthesis of the tripeptide glutathione.

Konrad Bloch dies at age 88 of congestive heart failure in Lexington, Massachusetts.

Konrad Bloch attends the former "Neisse Gymnasium".

Konrad Bloch joins the Institute of Organic Chemistry in Zurich as Guggenheim Fellow. Here he works with L. Ruzicka, V. Prelog and their colleagues. Bloch is truly inspired by the biogenetic considerations on terpene-sterol relationships developed by the Swiss.

Konrad Bloch joins Rudolf Schoenheimer’s research group. Schoenheimer and his associate David Rittenberg are stimulating Bloch's interest in intermediary metabolism and problems of biosynthesis. In 1942, in collaboration with David Rittenberg, Bloch starts working on the biological synthesis of cholesterol.

Bloch becomes Higgins Professor at Harvard University, and in 1968 Chairman of the Department. He deepens various aspects of terpene and sterol biogenesis. He studies the 27 carbon atoms in the cholesterol molecule showing that all natural steroid-related substances in humans are derived from cholesterol. He defines many of the steps involved in converting acetate into cholesterol. Bloch also works on the enzymatic formation of unsaturated fatty acids and on biochemical evolution.

Bloch and Rittenberg notice that the two-carbon compound acetic acid plays a main role in the biosynthesis of cholesterol. Bloch tries to define how acetic acid molecules combine in this process. He is helped by Lynen and his co-workers in Munich and by Sir Warcup Cornforth and Popják in England. Their discovery simplify the research on the relation of blood cholesterol levels to atherosclerosis, research in physiology and on the chemistry of terpenes, rubber and other isoprene derivatives.

Konrad Bloch is born in Nysa (Neisse), once Upper Silesia (Germany) as the son of Fritz Bloch and his wife Hedwig (née Striemer).

Konrad Bloch moves to the United States to enter the Department of Biochemistry, College of Physicians and Surgeons at Columbia University. Here he becomes a graduate student under Hans T. Clarke and earns his Ph.D. in 1938.

After his BSc in Chemistry, Konrad Bloch leaves Germany because of the rising discrimination. He accepts a temporary position at the Schweizerische Forschungsinstitut in Davos, Switzerland where he investigates the phospholipids of tubercle bacilli.
