Arthur Stoll, son of a teacher and school headmaster, studied from winter semester 1906/07 chemistry at the Federal Polytechnic in Zurich where he was at Richard Willstätter 1910 with a thesis about the reaction of Nitrosamiden with phenylhydrazine graduate and 1912 with a thesis About chlorophyllase and chlorophyllides Ph.D. has been. In the same year he followed Willstätter's assistant to the Kaiser Wilhelm Institute for Chemistry in Berlin, where he worked with him to develop essential knowledge about the importance of chlorophyll in carbon assimilation . In 1915 he moved with Willstätter from Berlin to the Ludwig Maximilians University in Munich to do his habilitation .

In 1917 he was appointed Royal Bavarian Professor of Chemistry. In the same year he was hired at the Sandoz Chemical Factory , where he was appointed head of the department to set up a new pharmaceutical department. At Sandoz he was President of the Board of Directors from 1949 to 1956 , and from 1964 he was Chairman of the Board of Directors .

Together with his employees, Stoll developed a number of processes for the production of medicines. He succeeded for the first time in isolating ergot alkaloids (such as ergotamine and ergobasin ) as well as cardiac glycosides , which are used as drugs for heart disease. Processes for the production of soluble calcium salts have also been developed. One of his main achievements is that he succeeded in isolating a number of pharmacologically active substances from a “ total drug” and thus incorporating them into specifically effective and therapeutically precise individual substances .

Stoll owned a modern art collection, which included the works Two Women in Flowers , Girl Study for the Chosen One and Feeling by Ferdinand Hodler .
