Vladimir Prelog. 23 July 1906—7 January 1998

Vladimir Prelog, one of the truly influential organic chemists of the past century, died in Zurich after a short illness on 7 January 1998. For his contributions to stereochemistry, he shared the 1975 Nobel Prize in Chemistry with J.W. Cornforth. In his 1991 autobiographical sketch (53)* Prelog told what he wanted to tell about himself and his work. The present memoir borrows heavily on this, but we have also drawn on our own perceptions gathered over many years of companionship and communion.
