Emil Fischer and supramolecular chemistry : The link between the discoverer of the lock‐and‐key concept and major aspects of this new branch of chemistry is tracked down by A.

He also comments on the two fundamental selection types—postsynthesis selection and presynthesis selection, or in other words, discovery and design.
