Swiss scientist Vladimir Prelog (friends called him "Vlado") developed x-ray analysis techniques to reveal the stereochemical structures of numerous complex organic molecules, and laid out the general rules of molecular structure in relation to the properties of chemical compounds. He also developed reliable systemic rules for using x-ray analysis to determine whether the atoms of a lopsided, or asymmetric, carbon-based molecule are arranged in "right-handed" or "left-handed" placement (either arrangement contains the same atoms, but the atoms are connected in mirror-image arrangements). He won the Nobel Prize for Chemistry in 1975, sharing the honor with John Cornforth.

Prelog was agnostic, and so strongly opposed to authoritarianism that when he was named as director of the laboratory at Swiss Federal Institute of Technology he instead reorganized the lab's responsibilities so that it operated efficiently without any further administrative efforts. He was the butt of his favorite joke, which he recounted often, in which he cajoled a colleague, Robert B. Woodward, to say something nice about the frequently grumpy chemist Sir Robert Robinson, and Woodward claimed that Robinson had said "Prelog is not a good chemist, but he is a nice person".

On 28 June 1914, when Prelog was almost eight years old and still living in his native Sarajevo, he was one of several dozen "flower boys" arrayed along the carriage route of Archduke Franz Ferdinand and his duchess, holding a basket of colorful pedals and leaves to shower onto the Archduke's parade path. Instead, of course, the Duke and Duchess were assassinated a few hundred feet from where the boy stood, launching the conflagration we now call World War I. During the second World War Prelog fled Nazi-occupied Zagreb and settled in Switzerland, where he became a citizen and worked for decades at the Swiss Federal Institute of Technology in Zürich.
