Sigmund Rascher (12 February 1909 – 26 April 1945) was a German SS doctor. He conducted deadly experiments on humans about high altitude, freezing and blood coagulation under SS leader Heinrich Himmler's patronage, to whom his wife Karoline "Nini" Diehl had direct connections. When police investigations uncovered that the couple defrauded the public with their supernatural fertility by 'hiring' and kidnapping babies, she and Rascher were arrested in April 1944. He was accused of financial irregularities, murder of his former lab assistant, and scientific fraud, and brought to Buchenwald and Dachau before being executed. After his death, the Nuremberg Trials judged his experiments as inhumane and criminal. [1]

<i>Schutzstaffel</i> Major paramilitary organization of Nazi Germany

The Schutzstaffel was a major paramilitary organization under Adolf Hitler and the Nazi Party (NSDAP) in Nazi Germany, and later throughout German-occupied Europe during World War II. It began with a small guard unit known as the Saal-Schutz made up of NSDAP volunteers to provide security for party meetings in Munich. In 1925, Heinrich Himmler joined the unit, which had by then been reformed and given its final name. Under his direction (1929–45) it grew from a small paramilitary formation to one of the most powerful organizations in Nazi Germany. From 1929 until the regime's collapse in 1945, the SS was the foremost agency of security, surveillance, and terror within Germany and German-occupied Europe.

Nazi human experimentation was a series of medical experiments on large numbers of prisoners, including children, by Nazi Germany in its concentration camps in the early to mid 1940s, during World War II and the Holocaust. Chief target populations included Romani, Sinti, ethnic Poles, Soviet POWs, disabled Germans, and Jews from across Europe.

Heinrich Himmler High Nazi Germany official, head of the SS

Heinrich Luitpold Himmler was Reichsführer of the Schutzstaffel, and a leading member of the Nazi Party (NSDAP) of Germany. Himmler was one of the most powerful men in Nazi Germany and among those most directly responsible for the Holocaust.


Early life

Sigmund Rascher was born the third child of Hanns-August Rascher (1880–1952) a physician and avid follower of Rudolf Steiner.[ citation needed ] Therefore, Rascher attended the first Waldorf School, a school based on Steiner's anthroposophist approach to education. He came under the influence of Ehrenfried Pfeiffer, who believed in the influence of cosmic rhythms on life processes. [2] He completed his secondary education, the German Abitur in Konstanz in 1930 or 1931—he used both dates. [3]

Rudolf Steiner Austrian esotericist

Rudolf Joseph Lorenz Steiner was an Austrian philosopher, social reformer, architect, and esotericist. Steiner gained initial recognition at the end of the nineteenth century as a literary critic and published philosophical works including The Philosophy of Freedom. At the beginning of the twentieth century he founded an esoteric spiritual movement, anthroposophy, with roots in German idealist philosophy and theosophy; other influences include Goethean science and Rosicrucianism.

Ehrenfried Pfeiffer was a German scientist, soil scientist, leading advocate of biodynamic agriculture, anthroposophist and student of Rudolf Steiner.


In 1933, he began to study medicine in Munich, where he also joined the NSDAP. The exact day of his joining is uncertain: Rascher insisted that it was on 1 March, whereas documents show 1 May. This is relevant in that the first date is 4 days before the Nazi victory in the German national election, March 1933, whereas the second date is after Hitler had consolidated power on 23 March with his Enabling Act. [4]

Medicine The science and practice of the diagnosis, treatment, and prevention of physical and mental illnesses

Medicine is the science and practice of establishing the diagnosis, prognosis, treatment, and prevention of disease. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others.

Munich Place in Bavaria, Germany

Munich is the capital and most populous city of Bavaria, the second most populous German federal state. With a population of around 1.5 million, it is the third-largest city in Germany, after Berlin and Hamburg, as well as the 12th-largest city in the European Union. The city's metropolitan region is home to 6 million people. Straddling the banks of the River Isar north of the Bavarian Alps, it is the seat of the Bavarian administrative region of Upper Bavaria, while being the most densely populated municipality in Germany. Munich is the second-largest city in the Bavarian dialect area, after the Austrian capital of Vienna.

Enabling Act of 1933 Transfer of the Reichstags power to the government under Hitler

The Enabling Act of 1933, formally titled Gesetz zur Behebung der Not von Volk und Reich, was an amendment to the Weimar Constitution that gave the German Cabinet — in effect, Chancellor Adolf Hitler — the power to enact laws without the involvement of the Reichstag. The Enabling Act gave Hitler plenary powers and followed on the heels of the Reichstag Fire Decree, which had abolished most civil liberties and transferred state powers to the Reich government. The combined effect of the two laws was to transform Hitler's government into a legal dictatorship.

After his medical internship, Rascher worked with his now divorced father in Basel, Switzerland, and continued his medical studies there, joining the Swiss Voluntary Work Forces. In 1934, he returned to Munich to finish his studies, and received his doctorate in 1936.[ citation needed ] In May 1936, Rascher joined the SA .[ citation needed ] From 1936 to 1938 Rascher worked on cancer diagnostics, supported by a DFG stipend under Prof. Trumpp in Munich.[ citation needed ] Until 1939 he was an assistant physician at Munich's hospital Schwabinger Krankenhaus.

Basel Place in Basel-Stadt, Switzerland

Basel is a city in northwestern Switzerland on the river Rhine. Basel is Switzerland's third-most-populous city with about 180,000 inhabitants.

Doctorate academic or professional degree

A doctorate or doctor's degree or doctoral degree is an academic degree awarded by universities that is, in most countries, a research degree that qualifies the holder to teach at the university level in the degree's field, or to work in a specific profession. There are a variety of doctoral degrees, with the most common being the Doctor of Philosophy (PhD), which is awarded in many different fields, ranging from the humanities to the scientific disciplines.

<i lang="de" title="German language text">Sturmabteilung</i> original Nazi paramilitary

The Sturmabteilung, literally Storm Detachment, was the Nazi Party's original paramilitary. It played a significant role in Adolf Hitler's rise to power in the 1920s and 1930s. Its primary purposes were providing protection for Nazi rallies and assemblies, disrupting the meetings of opposing parties, fighting against the paramilitary units of the opposing parties, especially the Red Front Fighters League of the Communist Party of Germany (KPD), and intimidating Romanis, trade unionists, and, especially, Jews – for instance, during the Nazi boycott of Jewish businesses.

In 1939, Rascher transferred to the SS with the rank of Private.[ citation needed ]

Career with the SS

In 1939 Rascher denounced his father, and was conscripted into the Luftwaffe. A relationship with and eventual marriage to former singer Karoline "Nini" Diehl gained him direct access to Reichsführer-SS Heinrich Himmler. Rascher's connection with Himmler gave him immense influence, even over his superiors. [6] Though it is unclear as to the precise nature of Diehl's connection to Himmler, she frequently corresponded with him and interceded with him on her husband's behalf; it is suggested that Diehl may have been a former lover of Himmler. [7]

<i>Reichsführer-SS</i> special title and rank in Nazi Germany (1925-1945)

Reichsführer-SS was a special title and rank that existed between the years of 1925 and 1945 for the commander of the Schutzstaffel (SS). Reichsführer-SS was a title from 1925 to 1933, and from 1934 to 1945 it was the highest rank of the SS. The longest serving and most noteworthy Reichsführer-SS was Heinrich Himmler.

A week after first meeting Himmler, Rascher presented a paper, "Report on the Development and Solution to Some of the Reichsfuehrer's Assigned Tasks During a Discussion Held on April 24, 1939". [6] Rascher became involved in testing a plant extract as a cancer treatment. Kurt Blome, deputy of the Reich Health Leader and Plenipotentiary for Cancer Research in the Reich Research Council, favoured testing the extract on rodents, but Rascher insisted on using human test subjects. Himmler took Rascher's side and a Human Cancer Testing Station was established at Dachau. Blome worked on the project. [6]

High altitude experiments

Rascher suggested in early 1941, while a captain in the Luftwaffe's Medical Service, that high-altitude/low-pressure experiments be carried out on human beings. [8] While taking a course in aviation medicine at Munich, he wrote Himmler a letter in which he said that his course included research into high-altitude flight and it was regretted that no tests with humans had been possible as such experiments were highly dangerous and nobody volunteered for them. Rascher asked Himmler to place human subjects at his disposal, stating quite frankly that the experiments might prove fatal, but that previous tests made with monkeys had been unsatisfactory. The letter was answered by Rudolf Brandt, Himmler's adjutant, who informed Rascher that prisoners would be made available. [9] [10]

Rascher subsequently wrote back to Brandt, asking for permission to carry out his experiments at Dachau, and plans for the experiments were developed at a conference in early 1942 attended by Rascher and members of the Luftwaffe Medical Service. The experiments were carried out in the spring and summer of the same year, using a portable pressure chamber supplied by the Luftwaffe. The victims were locked in the chamber, the interior pressure of which was then lowered to a level corresponding to very high altitudes. The pressure could be very quickly altered, allowing Rascher to simulate the conditions which would be experienced by a pilot freefalling from altitude without oxygen. After viewing a report of one of the fatal experiments, Himmler remarked that if a subject should survive such treatment, he should be "pardoned" to life imprisonment. Rascher replied to Himmler that the victims had to date been merely Poles and Russians, and that he believed they should be given no amnesty of any sort. [9]

Freezing experiments

Rascher also conducted so-called "freezing experiments" on behalf of the Luftwaffe on 300 test subjects without their consent. US investigators later concluded that Rascher had been merely a convenient front for Luftwaffe chief surgeon Erich Hippke, who had been the true source of the ideas for Rascher's experiments. [1] [8] [11] The experiments were conducted at Dachau after the high-altitude experiments had concluded. The purpose was to determine the best way of warming German pilots who had been forced down in the North Sea and suffered hypothermia. Rascher's victims were forced to remain outdoors naked in freezing weather for up to 14 hours, or kept in a tank of icewater for three hours, their pulse and internal temperature measured through a series of electrodes. Warming of the victims was then attempted by different methods, most usually and successfully by immersion in hot water; at least one witness, an assistant to some of these procedures, later testified that some victims were thrown into boiling water for rewarming. [12]

Himmler attended some of the experiments, and told Rascher he should go to the North Sea region and find out how ordinary people there warmed victims of extreme cold. Himmler reportedly said he thought "that a fisherwoman could well take her half-frozen husband into her bed and revive him in that manner" and added that everyone believed "animal warmth" had a different effect than artificial warmth. [13] Four Romani women were sent from Ravensbrück concentration camp and warming was attempted by placing the hypothermic victim between two naked women. [14] [15]

In October 1942, results of the experiments were presented at a medical conference in Nuremberg in two presentations named "Prevention and Treatment of Freezing", and "Warming Up After Freezing to the Danger Point". [16]

Rascher, who had by now been transferred to the Waffen-SS, was eager to obtain the academic credentials necessary for a high-level university position. A habilitation which was to be based on his research failed, however, at Munich, Marburg, and Frankfurt, due to the formal requirement that results be made available for public scrutiny. [17]

Similar experiments were conducted from July to September 1944, as the Ahnenerbe provided space and materials to doctors at Dachau to undertake "seawater experiments", chiefly through Wolfram Sievers. Sievers is known to have visited Dachau on 20 July 1944, to speak with Kurt Plötner and the non-Ahnenerbe Wilhelm Beiglboeck, who ultimately carried out the experiments.

While at Dachau, Rascher developed the standard cyanide capsules, which could be easily bitten through, either deliberately or accidentally. [18]

Blood coagulation experiments

Rascher experimented with the effects of Polygal, a substance made from beet and apple pectin, which aided blood clotting. He predicted that the preventive use of Polygal tablets would reduce bleeding from gunshot wounds sustained during combat or during surgery. Subjects were given a Polygal tablet, and shot through the neck or chest, or their limbs amputated without anaesthesia. Rascher published an article on his experience of using Polygal, without detailing the nature of the human trials and also set up a company to manufacture the substance, staffed by prisoners. [19]

Personal life and execution

Attempting to please Himmler through demonstrating that population growth could be accelerated by extending female childbearing age, Rascher publicized the fact that his wife Karoline had given birth to three children even after reaching 48 years of age, and Himmler used a photograph of Rascher's family as propaganda material. However, during her fourth "pregnancy," Mrs. Rascher was arrested while attempting to kidnap a baby. An investigation later revealed that her other three children had been either purchased or kidnapped. Himmler felt betrayed, and Rascher was arrested in April 1944.

In addition to acting as an accessory in the kidnappings of the three infants, Rascher was also accused of financial irregularities, the murder of his former lab assistant, and scientific fraud. Both Rascher and his wife were hastily condemned without trial to the concentration camps. [20] Rascher was imprisoned at Buchenwald following his arrest in 1944, until the camp's evacuation in April 1945. He and other prisoners were then taken to Dachau where Rascher was executed by firing squad on 26 April 1945, three days before the camp was liberated by American troops. [21] In another first hand account a fellow SS officer witnessed Rascher's execution by SS-Hauptscharführer Theodor Bongartz  [ de ] on Himmler's direct order by shooting him through the cell observation and food delivery door, then kicking his body with the words 'You pig, now you've got the punishment you deserve'. [22]

After his death, the Nuremberg Trials judged his experiments as inhumane and criminal. [1]

Unethical human experimentation is human experimentation that violates the principles of medical ethics. Such practices have included denying patients the right to informed consent, using pseudoscientific frameworks such as race science, and torturing people under the guise of research. Around World War II, Imperial Japan and Nazi Germany carried out brutal experiments on prisoners and civilians through groups like Unit 731 or individuals like Josef Mengele; the Nuremburg Code was developed after the war in response to the Nazi experiments. Countries have carried out brutal experiments on marginalized populations. Examples include American abuses during Project MKUltra and the Tuskegee syphilis experiments, and the mistreatment of indigenous populations in Canada and Australia. The Declaration of Helsinki, developed by the World Medical Association (WMA), is widely regarded as the cornerstone document on human research ethics.
