Vladimir Prelog

Born: July 23, 1906 | Sarajevo, YU
Died: January 7, 1998 | Zürich, CH

Vladimir Prelog reflects on his long and distinguished career as an organic chemist, from his formative years in Yugoslavia, his doctoral studies in Prague, his academic involvement at the Technical Faculty of the University of Zagreb, to his research at the Swiss Federal Institute of Technology (ETH). At ETH, Prelog has worked with the chemistry of natural products and stereochemistry while collaborating with Cahn and Ingold to create the CIP system for defining absolute configuration.

Abstract of Interview

In this interview Vladimir Prelog discusses his long and distinguished career as an organic chemist. He begins by recalling his early education in Yugoslavia, doctoral studies in Prague, and first job as a chemist. He returned to Yugoslavia in 1935 to teach at the Technical Faculty of the University of Zagreb. The interview continues with Prelog describing how he finessed the problems of war and foreign occupation by emigrating to Switzerland, where he began a 35-year affiliation with the Swiss Federal Institute of Technology (ETH). The central portion of the interview contains Prelog's reflections on his research at the ETH. This includes work with the chemistry of natural products and with stereochemistry, and his creation (with Cahn and Ingold) of the CIP system for defining absolute configuration. The interview concludes with Prelog speaking about the growing complexity and expense of chemical research, his relationships with American chemists, his current research, and the future of chemistry and chemical education.
