In 1892 Karrer's family returned to Switzerland where he was educated at Wildegg and at the grammar school in Lenzburg, Aarau, where he matriculated in 1908.
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.

Nobel prizes in Chemistry were successively awarded to Paul Karrer (in 1937) and Richard Kühn (in 1938) for their work on the structure and chemistry of the carotenoids.
Karrer and Jucker (1948), when dealing with the function of carotenoids, wrote "All these investigations are still at a preliminary stage and further researches will be required in order to elucidate the importance of carotenoids in plants." Similarly, Goodwin (1952) stated " with regard to formation and function (of carotenoids), knowledge is rudimentary".

Conrad Eugster studied chemistry at the University of Zurich, received his doctorate here in 1953 under the guidance of Paul Karrer, and became a Privatdozent in 1955.
Conrad Eugster also studied intensively the chemistry of quinones, including the isolation and structure determination of caryopterone, cordeauxiaquinone, and the reactions of quinones with nucleophiles for the synthesis of annelated quinones.
He made important contributions to the area of terpene and carotenoid chemistry; together with Peter Rüedi a large number of coloured tetra- and pentacyclic abietanoids were isolated from tropical plants of the Labiatae family, and the first syntheses of B,B-carotene and related carotenoids was completed in collaboration with Paul Karrer.
