Hans Kammler

Hans Kammler (26 August 1901 – 1945 [assumed]) 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 before being put in charge of the V-2 rocket and Emergency Fighter Programs towards the end of World War II.

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.

In 1931, Kammler joined the Nazi Party (NSDAP), where he held a variety of administrative positions after the Nazi government came to power in 1933.

Initially he was head of the Aviation Ministry's building department.

He joined the 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).

Committed to the Nazi cause, engineers like Kammler "saw no contradiction between notions of blood and soil and the methods of modern organization and technology."

Historian Michael Thad Allen argues that Kammler wanted to place "the best means of modern organization" at the Nazis' disposal since he believed that National Socialism was a "necessary catalyst" for modern construction.

For Kammler, the concepts of "modern technology, organization, and ideologies of German supremacy" were all interwoven.

Before joining Oswald Pohl's organization at the SS Main Economic and Administrative Office (WVHA), Kammler had already been advising the SS Race and Settlement Office as a consultant.

In June 1941, he joined the Waffen-SS.

Due to Himmler's desire to increase the pace and scale of SS construction activities Kammler was released as an adviser in the Reichskommissariat for the Reinforcement of Germandom, so his technical and managerial competencies could be exploited.

In the person of Kammler, Allen writes, "technological competence and extreme Nazi fanaticism coexisted in the same man."

Even Albert Speer—Hitler's chief architect—came to fear Kammler and placed him among "Himmler's most brutal and most ruthless henchmen."

Kammler was known to scrutinize the education of his subordinates as well as their ideological commitment to National Socialism, which he factored into their duty assignments and promotions.

Immediately after being assigned to the WVHA, Kammler became Pohl's deputy, where he worked with SS-Gruppenführer Richard Glücks of Office D (Concentration Camps Inspectorate), and was also named Chief of Office C, which designed and constructed all the concentration and extermination camps.

On 26 September 1941—just days after the announcement of the plan for Majdanek—Kammler ordered the construction of the largest of the camps at Auschwitz.

On 19 December 1941, Kammler updated Himmler about the slow progress at both Auschwitz-Birkenau and Majdanek, remarking that construction was delayed due to the freezing weather, lack of materials, and insufficient manpower.

By late March 1942, the systematic mass deportation of Jews to Auschwitz had begun.

Historian Nikolaus Wachsmann states that Kammler "was intimately involved in all the major building projects in Auschwitz."

For instance, in his capacity within the WVHA, Kammler oversaw the installation of more efficient cremation facilities at Auschwitz-Birkenau, when the Nazis converted it into an extermination camp.

Under Kammler's supervision, new crematoria were planned during August 1942 at Birkenau to facilitate burning up to one-hundred twenty thousand corpses per month.

After the RAF successfully bombed the rocket production facilities at Peenemünde during August 1943, Reich Ministry of Armaments and War Production Albert Speer recommended transferring the V-2 rocket production underground.

Hitler immediately agreed with Speer, and the two decided that the SS, with its massive supply of slave labor, was best suited for this task.

As the SS construction chief, Kammler was selected to oversee the project—along with representatives Gerhard Degenkolb and Karl Maria Hettlage from Speer's ministry—which began at a huge fuel storage facility in Thuringia under the Mittelwerke GmbH.

By the end of August 1943, Kammler had a sizable detachment of concentration camp inmates from Buchenwald working at the new underground installation, and before the year was out there were so many slave laborers that another facility (Mittelbau-Dora concentration camp) had to be established.

The secret weapons projects for which Kammler was given responsibility included manufacturing both the Messerschmitt Me 262 and the V-2, which Kammler—in a construction effort of ruthless brutality and speed—had in production before the end of 1943.

The tunnels and weapons were built in horrendous conditions by the slave laborers from Mittelbau-Dora.

Research has found that of the 60,000 people that passed through Mittelbau-Dora camp, an estimated 10,000 died producing the V2 alone, which is double the roughly 5,000 killed by the weapon system in Britain and Belgium combined.

More than 20,000 died at Mittelbau-Dora in total throughout the camp's existence.

Kammler's attitude towards the prisoners was utter indifference, having once exclaimed, "Don't worry about the victims. The work must proceed ahead in the shortest time possible".

Speer made Kammler his representative for "special construction tasks", expecting that Kammler would commit himself to working in harmony with the ministry's main construction committee.

But in March 1944 Kammler had Göring appoint him as his delegate for "special buildings" under the fighter aircraft program, which made him one of the war economy's most important managers, and robbed Speer of much of his influence.

Kammler was also involved in an attempt to finish the Blockhaus d'Éperlecques near Saint-Omer, Pas-de-Calais in Northern France.

The fortified bunker was to be used as a V-2 launch base but it was abandoned in September 1944 before it was finished.

Kammler disappeared in May 1945 during the final days of the war.

There has been much conjecture regarding his fate.

Kammler was born in Stettin, German Empire (now Szczecin, Poland).
