The first Danish chairs of ophthalmology

In the last century German medical sciences made up the chief inspiration to the medical profession in Europe. The influence of German ophthalmology spread to Denmark, and accordingly the first Danish professor, Edmund Hansen Grut was trained in the Graefe clinic. His successor, Jannik Bjerrum grew up in southern Jutland, a district later on lost to the German Empire. The hitherto prevailing Danish sympathies with the neighbour in the south vanished after this. Bjerrum thus wrote all his papers in Danish and made no efforts to achieve an international reputation. In contrast, Marius Tscherning, received widespread recognition as a scientist. He spent many years in France. His scientific insights at last brought him to the Danish chair of ophthalmology. The history of the first three professors of ophthalmology, so different in their attitudes, has narrative value, but exemplifies as well the rapid development of the profession in the years 1886–1925.
