Born in Munich on 5 July 1871, Schilling studied medicine in his native city, receiving a doctor's degree there in 1895. He was a professor of parasitology at the University of Berlin and a member of Malaria Commission of the League of Nations.. Within a few years, Schilling was practicing in the German colonial possessions in Africa. Recognized for his contributions in the field of tropical medicine, he was appointed the first-ever director of the tropical medicine division of the Robert Koch Institute in 1905, where he would remain for the subsequent three decades.
Italian research
Upon retirement from the Robert Koch Institute in 1936, Schilling moved to Benito Mussolini's FascistItaly, where he was given the opportunity to conduct immunization experiments on inmates of the psychiatric asylums of Volterra and San Niccolò di Siena. As Schilling stressed the significance of the research for German interests, the Nazigovernment of Germany also supported him with a financial grant for his Italian experimentation.
Dachau experiments
Schilling returned to Germany after a meeting with Leonardo Conti, the Nazis' Health Chief, in 1941, and by early 1942 he was provided with a special malaria research station at Dachau's concentration camp by Heinrich Himmler, the leader of the SS. Despite negative assessments from colleagues, Schilling would remain in charge of the malaria station for the duration of the war. . In his hand he holds records showing that hundreds of priests died at the camp after being exposed to malaria during Nazi medical experiments. Although in the 1930s Schilling had stressed the point that malaria research on human subjects could be performed in an entirely harmless fashion, the Dachau subjects included prisoners who were injected with synthetic drugs at doses ranging from high to lethal. They had been exposed to malaria mosquitos in cages strapped to their hands or arms so as to ensure infection with the parasite. Of the more than 1,000 prisoners used in the malaria experiments at Dachau during the war, between 300 and 400 died as a result; among survivors, a substantial number remained permanently injured. A number of priests imprisoned by the Nazis were killed during the experiments. In the course of the Dachau Trials following the liberation of the camp at the close of the war, Schilling was tried by a U.S. General Military Court, appointed at 2 November 1945, in the case of The United States versus Martin Gottfried Weiss, Wilhelm Rupert, et al. The defendants, 40 doctors and staff, were charged and convicted of offenses of the violations of laws and usages of war in that they acted in pursuance of a common design, did encourage, aid, abet, and participate in the subjection of Allied nationals and prisoners of war to cruelties and mistreatments at Dachau Concentration Camp and its subcamps. According to the August H. Vieweg testimony, the patients used in the malaria experiments were Poles, Russians, and Yugoslavs. At that time there was no formal code of ethics in medical research to which the judges could hold the accused Nazi doctors accountable. The "scientific experiments" exposed during the trials lead to the Nuremberg Code, developed in 1949 as a ten-point code of human experimentation ethics. The tribunal sentenced Schilling to death by hanging on 13 December 1945. His execution took place at Landsberg Prison in Landsberg am Lech on 28 May 1946. The execution was filmed by military personnel, who recorded Schilling's ascending the gallows and his hanging, along with a coffin marked "Dr Schilling, Claus."
