Tadeus Reichstein isolates and explains the constitution of aldosterone, a hormone of the adrenal cortex, which until then had not been isolated, in collaboration with S.A.S. Simpson and J.F. Tait (London), A. Wettstein and R. Neher (Ciba Ltd, Basel), and M. Tausk (NV Organon, Oss, The Netherlands).

Tadeus Reichstein receives one third of the Nobel Prize in Physiology or Medicine along with Edward C. Kendall and Philip S. Hench "for their discoveries relating to the hormones of the adrenal cortex, their structure and biological effects".

Tadeus Reichstein becomes Lecturer at the E.T.H. He lectures on organic and physiological chemistry and in 1931 he becomes Assistant to Professor L. Ruzicka. In 1933 Reichstein succeeds also, independently of Sir Norman Haworth and his collaborators in Birmingham, in synthesizing vitamin C (ascorbic acid).

Reichstein works on the isolation of the volatile flavour components of roasted coffee for the German company Frank (Kathreiner’s malt coffee) together with his assistant and friend Joseph von Euw in a small laboratory in Albisrieden. He finds that the aroma of coffee is composed of complex substances, among which are derivatives of furan and pyrrole, and substances containing sulphur. Reichstein publishes a series of papers on these substances, and also on the aromatic substances in chicory.

Tadeus Reichstein begins his doctorate under the supervision of Nobel Laureate Hermann Staudinger. At the same time, Reichstein works with Leopold Ruzicka, an assistant of Staudinger. Collaborating in the cellar laboratory at the ETHZ, Reichstein benefits very much from Ruzicka's great practical skills.

Tadeus Reichstein happily rejoins his family in Zurich where he receives private tuition at home for seven years. During these years Reichstein develops an insatiable thirst for knowledge and his amazement for the wonders of nature and especially of plants.

Tadeus Reichstein is appointed Titular Professor at the University of Basel. In 1937 he becomes Associate Professor, and in 1938 Professor in Pharmaceutical Chemistry, and Director of the Pharmaceutical Institute. In 1946 he takes over, in addition, the Chair of Organic Chemistry and he holds both these appointments until 1950.

Escaping from Russian to Switzerland because of the horrific pogroms against Russia’s Jewish population, Reichstein's parents decide to seek refuge in Switzerland. On their way to Zurich they leave Tadeus at a boarding school in Jena, where the little child will endure the violent methods of punishment of his teachers.

Tadeus Reichstein spends his early childhood in Kiev where his father sets up his own business as an engineer specializing in sugar processing plants.

Tadeus Reichstein enters the Eidgenössische Technische Hochschule where he receives his diploma in chemistry.

Tadeus Reichstein in the mid-1930's begins his pioneering work on the hormones produced in the adrenal glands, which are located above the kidneys. During this studies Reichstein discovers several biologically active substances including corticosterone, the anti-inflammatory agent now known as cortisone. At the same time, similar independent research on cortisone is being done in America by Prof. Edward C. Kendall at the Mayo Clinic in Minnesota.

Tadeus Reichstein becomes Director of the new Institute of Organic Chemistry at the University of Basel, the building of which he had supervised about a decade earlier. After being made Emeritus Professor in 1967, Reichstein works on the phytochemistry and cytology of ferns, publishing at least 80 papers on these subjects in the last three decades of his life.

Tadeus Reichstein finds a job in Rorschach in a chemical company. His duty is to improve batteries for flashlights. Reichstein is happy to have a well-paid job to contribute to the family budget.

Tadeus Reichstein is born in Wloclawek, at that time in the Russian part of Poland, to Isidor Reichstein, an engineer, and Gastava Brockmann. Reichstein is the oldest of five sons.

Tadeus Reichstein attends the Oberrealschule and also does his military service.

Tadeus Reichstein dies in Basel at age 99. The principal industrial process for the artificial synthesis of Vitamin C still bears his name.

Barry Marshall accepts a part-time appointment at the Pennsylvania State University spending there part of the spring semester each year.
