Beginning of February
The "race researcher" Robert Ritter has the SS present him with Sinti in custody in the camp for scientific evaluation.
After typhus spreads to villages situated to the north of the camp, the SS are compelled to adopt measures to improve the water supply.
The new special registry office "Weimar II" in the camp command area commences its work, which consists primarily in the registration of deaths.
After the war begins, 8,500 men are committed to the camp, among them some 700 Czechs, hundreds of Burgenland Roma, more than 2,200 Poles and more than a thousand Viennese Jews.
The SS crowd more than 3,000 Poles and Jews into a special camp consisting of tents on the muster ground. Their treatment of these persons is characteristic of systematic mass murder.
A dysentery epidemic breaks out. The spread of the disease to the surrounding villages leads to a conflict with the government health authorities.
After the attempt to assassinate Hitler in Munich the previous evening, the SS take revenge on the Jewish inmates. An execution squad murders 21 Jews in the quarry. All other Jews in the camp are deprived of food for three days.
There are 11,807 inmates in the camp. In 1939, 1,378 inmates have died in Buchenwald.
