During World War I, Thorvald Madsen in his capacity as director of Statens Serum Institut was heavily involved in humanitarian work for prisoners of war. From 1916 onwards Madsen did several inspection visits to detention centers in Russia, where conditions were highly questionable. During these travels brought Thorvald Madsen, among other things excess serum against various diseases. In addition, Madsen helped more Danish-Schleswigers, who had been in German military service and ended up a prisoner of war. Thorvald Madsen was also involved in the work of selecting sick prisoners of war who were sent to Denmark as part of the conditions of prisoner exchanges between, on the one hand, Austria-Hungary and Germany on the other hand, Russia.[1]
