  • 1937 - Davy Medal, Royal Society of London (UK) In recognition of his work on the chemistry of the porphyrins, particularly his determination of their detailed structure by degradation and his syntheses of porphyrins of biological importance
  • 1929 - Liebig-Denkmünze (Liebig Medal), Society of German Chemists

Overview

Hanns Fischer was a researcher affiliated with the University of Zurich in Switzerland. Their work contributed to the field of chemistry, with a particular focus on the study of porphyrins. Fischer's research involved the determination of detailed structures of porphyrins through degradation methods, as well as the synthesis of biologically important porphyrins.

Throughout their career, Fischer received recognition for their contributions to chemistry. Notably, Fischer was awarded the Liebig-Denkmünze (Liebig Medal) by the Society of German Chemists in 1929. Further acknowledgment came in 1937 with the Davy Medal from the Royal Society of London (UK), awarded in recognition of Fischer's work on the chemistry of porphyrins, particularly for the determination of their structures and synthetic methods.

Fischer's research output has influenced studies related to the chemistry of natural compounds involving porphyrin structures. This area encompasses tests of chemical degradation and synthesis techniques aimed at understanding molecular configurations.
