Bruno Nikolaus Maria Weber (21 May 1915 in Trier – 23 September 1956 in Homburg) was a German physician, bacteriologist and Hauptsturmführer (1944), at Auschwitz, in the branch of the Hygiene Institute of the Waffen SS.
On the ramp in the Birkenau camp, he took part in the selection of Jews deported to Auschwitz, the majority of whom were murdered by the Nazis in the gas chambers immediately after arrival.
In 1942 the Wehrmacht transferred him to the Waffen SS, where he reached the rank of Obersturmführer in January 1943, and was promoted to Hauptsturmführer in November 1944.
By May 1943, Weber was Head of the Sanitary-bacteriological investigation authority of the Waffen-SS and Police South-East in the central warehouse Rajsko of Auschwitz I.
At the instigation of the SS garrison doctor Eduard Wirths, this institute was used for the containment of typhoid and other epidemics.
