Hans Kammler (26 August 1901 – after October 1945) was an SS-Obergruppenführer responsible for Nazi civil engineering projects and its top secret V-weapons program. He oversaw the construction of various Nazi concentration camps, including Auschwitz, before being put in charge of the V-2 rocket and Emergency Fighter Programs towards the end of World War II. Kammler disappeared in May 1945 during the final days of the war, although conjecture about his capture or death remains.

Early life

Kammler was born in Stettin, German Empire (now Szczecin, Poland). In 1919, after volunteering for army service, he served in the Rossbach Freikorps. From 1919 to 1923, he studied civil engineering at the Technische Hochschule der Freien Stadt Danzig and Munich and was awarded his doctorate of engineering (Dr. Ing.) in November 1932, following some years of practical work in local building administration.

Nazi activist

In 1931, Kammler joined the Nazi Party (NSDAP), where he held a variety of administrative positions after the Nazi government came to national power in 1933. Initially he was head of the Aviation Ministry's building department. He joined the Schutzstaffel (SS) on 20 May 1933. In 1934, he was serving the Reich's Ministry as the leader of the Reichsbund der Kleingärtner und Kleinsiedler (Reich's federation of allotment gardeners and small home owners).
