concentration camp, it functioned as an extermination camp or death camp. Medical experiments and scientific racism Prisoners were used for medical experiments and their illnesses or their recoveries from them were used for research. Experiments on live prisoners were performed by Dr. Bofinger, who injected Herero who were suffering from scurvy with various substances including arsenic and opium; afterwards he researched the effects of these substances via autopsy. Experimentation with the dead body parts of the prisoners was rife. Zoologist (1872–1955) noted taking "body parts from fresh native corpses" which according to him was a "welcome addition", and he also noted that he could use prisoners for that purpose. An estimated 300 skulls were sent to Germany for experimentation, in part from concentration camp prisoners. In October 2011, after three years of talks, the first 20 of an estimated 300 skulls stored in the museum of the Charité were returned to Namibia for burial. In 2014, 14 additional skulls were repatriated by the University of Freiburg. Number of victims A census conducted in 1905 revealed that 25,000 Herero remained in German South West Africa. According to the Whitaker Report, the population of 80,000 Herero was reduced to 15,000 "starving refugees" between 1904 and 1907. In Colonial Genocide and Reparations Claims in the 21st Century: The Socio-Legal Context of Claims under International Law by the Herero against Germany for Genocide in Namibia by Jeremy Sarkin-Hughes, a number of 100,000 victims is given. Up to 80% of the indigenous populations were killed. Newspapers reported 65,000 victims when announcing that Germany recognized the genocide in 2004. Aftermath With the closure of concentration camps, all surviving Herero were distributed as labourers for settlers in the German colony. From that time on, all Herero over the age of seven were forced to wear a metal disc with their labour registration number, and banned from owning land or cattle, a necessity for pastoral society. About 19,000 German troops were engaged in the conflict, of which 3,000 saw combat. The rest were used for upkeep and administration. The German losses were 676 soldiers killed in combat, 76 missing, and 689 dead from disease. The Reiterdenkmal () in Windhoek was erected in 1912 to celebrate the victory and to remember the fallen German soldiers and civilians. Until after Independence, no monument was built to the killed indigenous population. It remains a bone of contention in independent Namibia. The
