Early years

Karrer was born in Frankfurt-am-Main. In 1919 he became Professor of Chemistry and Director of the Chemical Institute.


Karrer's early research concerned complex metal compounds but his most important work has concerned retina. Later, Karrer confirmed the structure of ascorbic acid (vitamin C) and extended his researches into the vitamin B2 and E. His important contributions to the chemistry of the flavins led to identification of lactoflavin as part of the complex originally thought to be vitamin B2.

Karrer published many papers, and received many honours and awards, including the Nobel Prize in 1937. His textbook Lehrbuch der Organischen Chemie (Textbook of Organic Chemistry) was published in 1927, went through thirteen editions, and was published in seven languages.

Personal life

Karrer was married to Helena Froelich in 1914 and had three sons, one of whom died in infancy.[1] He died June 18, 1971, at the age of 82 in Zürich. His wife died in 1972.


The prestigious Paul Karrer Gold Medal and lecture was established in his honour in 1959 by a group of leading companies such as CIBA AG, J.R. Geigy, F. Hoffmann-La Roche & Co. AG, Sandoz AG, Société des Produits Nestlé AG and Dr. A. Wander AG. It is awarded annually or biennually to an outstanding chemist who delivers a lecture at the University of Zurich. [2]
