About Richard Martin Willstätter, Nobel Prize in Chemistry, 1915

Richard Martin Willstätter (13 August 1872 – 3 August 1942) was a German organic chemist whose study of the structure of plant pigments, chlorophyll included, won him the 1915 Nobel Prize for Chemistry. Willstätter invented paper chromatography independently of Mikhail Tsvet.

Biography

Willstätter was born in to a Jewish family in Karlsruhe. He went to school there and, when his family moved, he attended the Technical School in Nuremberg. At age 18 he entered the University of Munich to study science and stayed for the next fifteen years. He was in the Department of Chemistry, first as a student of Adolf von Baeyer -- he received his doctorate in 1894 - then as a faculty member. His doctoral thesis was on the structure of cocaine. Willstätter continued his research into other alkaloids and synthesized several of them. In 1896 he was named Lecturer and in 1902 Professor extraordinarius (professor without a chair).

In 1905 he left Munich to become professor at the ETH Zürich and there he worked on the plant pigment chlorophyll. He determined its structure.

In 1912 he became professor of chemistry at the University of Berlin and director of the Kaiser Wilhelm Institute for Chemistry, studying the structure of pigments of flowers and fruits.

In 1916 he returned to Munich as the successor to his mentor Baeyer. During the 1920s Willstätter investigated the mechanisms of enzyme reactions and did much to establish that enzymes are chemical substances, not biological organisms.

In 1924 Willstätter's career came to "a tragic end when, as a gesture against increasing antisemitism, he announced his retirement." According to his Nobel biography: "Expressions of confidence by the Faculty, by his students and by the Minister failed to shake the fifty-three year old scientist in his decision to resign. He lived on in retirement in Munich....Dazzling offers both at home and abroad were alike rejected by him."

In 1938 Willstätter emigrated to Switzerland. He spent the last three years of his life there in Muralto near Locarno writing his autobiography. He died of a heart attack in 1942.

Willstätter's autobiography, Aus meinem Leben, was not published in German until 1949. It was translated into English as From My Life in 1965.

-----------------------------------------------------------------------

Richard Martin Willstätter was born in Karlsruhe in Baden on August 13, 1872, and went to school first in his home town and then, when his parents moved house, at the Technical School in Nuremberg. When he was 18 he went to the University of Munich where he studied Science, entered the Department of Chemistry under Baeyer and stayed there for the following fifteen years, first as a student, from 1896 as a lecturer - pursuing his scientific work independently - until in early 1902 he became J. Thiele's successor as Extraordinary Professor.

As a young man he studied principally the structure and synthesis of plant alkaloids such as atropine and cocaine. In this, as in his later work on quinone and quinone type compounds which are the basis of many dyestuffs, he sought to acquire skill in chemical methods in order to prepare himself for the extensive and more difficult work of investigating plant and animal pigments. For this undertaking the working facilities which the Munich laboratory afforded him were too limited and he was glad to accept the first offer of a Professorial Chair which he received in the summer of 1905. It was thus that he came to Zurich to the Federal Technical College.

These seven years in Switzerland were for him the best and most significant. But while research and teaching brought him great satisfaction, at the same time he suffered personal misfortune and soon became lonely. He enjoyed his work in Zurich so much that he did not think of those years as a waiting period until he was called back to Germany in 1912. For the Jubilee of the University of Berlin, Kaiser Wilhelm had established a Society for the Promotion of Scientific Knowledge and this body had founded an Institute of Chemistry in Berlin/Dahlem. He was offered a Research Laboratory here in conjunction with an honorary professorship at the University of Berlin.

In the two short years before the outbreak of the first World War he was able with a team of collaborators to round off his investigations into chlorophyll and, in connexion with that, to complete some work on haemoglobin and, in rapid succession, to carry out his studies of anthocyanes, the colouring matter of flowers and fruits. These investigations into plant pigments, especially the work on chlorophyll, were honoured by the award of the Nobel Prize for Chemistry (1915), just at the time when he had decided to accept a call to the University of Munich and again, as successor to his old teacher Adolf von Baeyer, take an active part in university teaching; for, as things were then, the even tenour of scientific life at Dahlem was gone.

In the period that followed Willstätter continued on lines of fundamental importance, and his brilliant and fruitful work is regarded today as a pioneering achievement. The investigations into photosynthesis and into the nature and activity of the enzymes were precursory of modern Biochemistry. At that time the method so far developed of concentrating enzymes through adsorption did not make it possible to attain to the crystallized enzymes. In this connexion, Willstätter carried out important studies of adsorbents, metal hydroxides, hydrogels and silicic acids. In addition he was quick to give his attention also to problems of theoretical chemistry. Thus he achieved the first synthesis of cyclo-octatetraene, and went on to compare it with benzene; so also he set up experiments to produce cyclobutadiene.

Willstätter's career came to a tragic end when, as a gesture against increasing antisemitism, he announced his retirement in 1924. Expressions of confidence by the Faculty, by his students and by the Minister failed to shake the fifty-three year old scientist in his decision to resign. He lived on in retirement in Munich, maintaining contact only with those of his pupils who remained in the Institute and with his successor, Heinrich Wieland, whom he had nominated. Dazzling offers both at home and abroad were alike rejected by him. In 1938 he fled from the Gestapo with the help of his pupil A. Stoll and managed to emigrate to Switzerland, losing all but a meagre part of his belongings.

Willstätter was married to Sophie Leser, the daughter of a Heidelberg University professor. They had one son, Ludwig, and one daughter, Ida Margarete.

The old man passed the last three years of his life in Muroalto near Locarno writing his Biography (Aus meinem Leben, edited by A. Stoll, Verlag Chemie, Weinheim, 1949; English edition From my Life, Benjamin, New York, 1965) until he died on 3rd August, 1942, of a heart attack.

In 1956 a memorial to Richard Willstätter was unveiled in Muroalto.

In an epilogue written by A. Stoll to Willstätter's Biography the list of honours and distinctions accorded to this great scholar in every part of the civilized world alone occupies no less than three pages.
