Walther Nernst was awarded the 1920 Nobel Prize in Chemistry.
The stamp shows a portrait of Walther Nernst together with a schematic of the Nernst Lamp which he invented in 1897 at the Göttingen physicochemical institute (which he had founded in 1895). However, the Nobel Prize was awarded "in recognition of his work in thermochemistry" (in particular his Heat Theorem, discovered in 1905).
The stamp of Walther Nernst was sold together with a stamp of Charles-Edouard Guillaume (1920 Nobel Prize in Physics) in the form of a little booklet (design: Jan Magnusson) containing a total of 10 stamps.
