Biography
German chemist. He received his Ph.D. under Alfred Werner, the "father of coordination chemistry," at the University of Zurich. His thesis, submitted in 1898, dealt with adducts of tinhalides. Pfeiffer was considered Werner's most successful student and became Werner's assistant until, due to a dispute with his mentor, he left first for Rostock, then Karlsruhe, and finally Bonn. At Bonn, where he had studied as an undergraduate, he occupied Kekulé's chair.
Pfeiffer's work spanned many themes. The Pfeiffer effect, which involves interactions between chiral solutes, is named after his discoveries. His group first made the salen ligands, which gave the first artificial oxygen carriers. He recognized that crystals, e.g. of zinc sulfide, are large molecules.
He died 4 March 1951.
