Hermann Staudinger (1881-1965)

German chemist, professor in Karlsruhe, Zurich and, from 1926, Freiburg. He discovered ketenes and, in 1919 with Jules Meyer, the reaction of azides with phosphines that bears his name (the Staudinger reaction).

He argued, against the majority view of his time, that polymers are giant molecules held together by covalent bonds, macromolecules. For this he received the 1953 Nobel Prize in Chemistry.
