Abstract

The picture for the German Congress of Endocrinology from 20.3 to 22.3.2019 in Göttingen shows Arnold-Adolf Berthold, Adolf Windaus and Werner Creutzfeld, in the background the auditorium of the university. The colorful and prominent cock refers to the pioneering experiments of Berthold, who transplanted testicles in chickens, which then took properties of the taps. The sun and the steroid formula indicate the importance of vitamin D. Windaus received the Nobel Prize for the characterization of vitamin D. The design of the congress logo comes from Mrs. Conny Blaack from Göttingen. In Göttingen, Arnold-Adolf Berthold (1801-1863) carried out the first basic endocrinological experiments. He is considered one of the founders of our field and is the namesake of our Berthold Lecture. Berthold was Professor of Physiological Anatomy and Natural History. In 1849, he established a link between male sexual and behavioral characteristics and a substance secreted by the testes and was able to show that transplanted testes cause these effects by secretion of a substance into the bloodstream. Werner Creutzfeld (1924-2006), who chaired the Department of Internal Medicine from 1964-1992 and later Gastroenterology and Endocrinology, has also significantly influenced the modern therapy of diabetes mellitus through groundbreaking work on the incretin concept and GLP-1. For the connection of Göttingen to osteology Adolf Windaus (1876-1959). He was awarded the Nobel Prize in Chemistry in 1928 for his contributions to the study of the structure of sterols and their association with vitamins, especially vitamin D and vitamin A. The chemical synthesis of vitamin D is based on his work and has been used by many children in the industrial age Problems of osteomalacia solved.
