LETTER FROM HIMMLER TO RASCHER, 24 OCTOBER 1942, AND NOTE BY RUDOLF BRANDT

Field Command Post, 24 Oct 1942

Top Secret

Dear Rascher!

I acknowledge the receipt of your letter of the 9th and 10th and both notes of 16 October 1942.

I have read your report regarding cooling experiments on humans with great interest. SS Sturmbannfuehrer Sievers should arrange the possibility of evaluation at institutes which are connected with us.

I regard these people as guilty of treason and high treason, who, still today, reject these experiments on humans and would instead let sturdy German soldiers die as a result of these cooling methods. I shall not hesitate to report these men to the offices concerned. I empower you to make my opinion on this known to the offices concerned.

I invite you to a personal conference in November as I cannot make it sooner despite my great interest.

SS Obergruppenfuehrer Wolff will once again get in touch with Field Marshal Milch. You are empowered to make a report to Field Marshal Milch—and, of course, to the Reich Marshal if he has time—concerning those who are not doctors.

I think that covers which have heat packets or something similar sewed in their lining are the best for the warming of those who were stranded at sea and were picked up in boats or small vessels and where there is no possibility of placing these chilled people in a hot bath. I take it for granted that you know these heat packets which we also have in the SS and which were used by the Russians a great deal. They consist of a mass which develops a warmth of 70° to 80° upon addition of water and retains it for hours.

I am very curious as to the experiments with body warmth. I personally take it that these experiments will probably bring the best and lasting results. Naturally, I could be mistaken.

Keep me informed on future findings. Of course we will see each other in November.

Heil Hitler!

Yours

MEMORANDUM OF RASCHER ON WOMEN USED FOR REWARMING IN FREEZING EXPERIMENTS, 5 NOVEMBER 1942

Sigmund Rascher, M. D.

Munich, Trogerstrasse 56, 5 November 1942

Subject: Requested report on concentration camp prostitutes.

For the resuscitation experiments by animal warmth after freezing as ordered by the Reich Leader SS I had four women assigned to me from the women’s concentration camp Ravensbrueck.

One of the assigned women shows unobjectionably Nordic racial characteristics: blond hair, blue eyes, corresponding head and body structure, 21¾ years of age. I asked the girl why she had volunteered for the brothel. I received the answer: “To get out of the concentration camp, for we were promised that all those who would volunteer for the brothel for half a year would then be released from the concentration camp”. To my objection that it was a great shame to volunteer as a prostitute, I was told: “Rather half a year in the brothel than half a year in the concentration camp”. Then followed an account of a number of most peculiar conditions at camp Ravensbrueck. Most of the reported conditions were confirmed by the three other prostitutes and by the female warden who had accompanied them from Ravensbrueck.

It hurts my racial feelings to expose to racially inferior concentration camp elements a girl as a prostitute who has the appearance of a pure Nordic and who could perhaps by assignment of proper work be put on the right road.

Therefore, I refused to use this girl for my experimental purposes and gave the adequate reports to the camp commander and the adjutant of the Reich Leader SS.

LETTER FROM SIEVERS TO BRANDT, 28 JANUARY 1943, AND
RASCHER’S REPORT ON HIS DISCUSSIONS WITH GRAWITZ AND
POPPENDICK

[illegible shorthand notes]

Secret!

I submit to you enclosed a documentary note of Dr. Rascher on his discussion with the Reich Physician SS [Reichsarzt SS] of 13 January 1943. I would be much obliged to you if you could advise us as to what attitude we or Dr. Rascher are to take in the future. I am slightly astonished about the course of the discussion, for the orders of the Reich Leader SS were especially to the effect that we—that is the Ahnenerbe—were to take Dr. Rascher’s work under our care. The argument of SS Gruppenfuehrer Grawitz, that it constituted an unbearable situation to have a non-physician give information on medical matters, is not pertinent. I have never claimed to be a judge of medical matters, nor do I consider it as one of my duties. My duty merely consists of smoothing the way for the research men and seeing that the tasks ordered by the Reich Leader SS are carried out in the quickest possible way. On one thing I certainly can form an opinion—that is, on who is doing the quickest job.

If things are to go on in the future as SS Gruppenfuehrer Grawitz desires, I am afraid that Dr. Rascher’s work will not continue to advance as fast and unhampered as hitherto.

With comradely greetings,

Heil Hitler!

Yours

COPY

Rascher: Reports on freezing experiments with water and emphasizes that they have been concluded practically, but not in theory.

Grawitz: Question about the memorandum. Whether Rascher believes this to be absolutely established for dry freezings, too?

Rascher: No, a lot of theoretical work is still to be done, primarily many practical experiments have still to be conducted.

Grawitz: That is my opinion, too. We cannot distribute a memorandum to the troops, abolishing all former views, if this is not entirely well-founded, as otherwise uncertainties will arise among the troops. I shall write to Obersturmbannfuehrer Dr. Brandt that I am asking the Reich Leader SS not to distribute the memorandum before a well-founded method of treatment of dry frozen persons has been established.

Rascher: Very well, that’s why the Reich Leader SS gave me the order of 13 December 1942. But I urgently want to emphasize that the results of the freezing experiments with water have been established and are well-founded.

Grawitz: Well, now, this had to be mentioned in the letter to Brandt so that you are not blamed in any way! You see, from my former activities (mention of some hospital) I know so much about metabolism that I am almost a specialist in this field and can help you enormously.

Rascher: As I understood, Gruppenfuehrer, that’s why I am to turn to your office for glass materials, chemicals, etc.

Grawitz: No. Not only for that. You have to turn to me in all medical matters, since after all, I am Reich Physician SS and all medical affairs are subordinate to me. It is absolutely necessary that all medical matters destined for the Reich Leader SS go through my office.

Rascher: I don’t know, Gruppenfuehrer, if this was the intention. I am under the direct orders of the Reich Leader SS and I have always reported directly to him. I have never received orders to another effect.

Grawitz: You certainly will be transferred to the Waffen SS?

Rascher: Yes, I hope so. The transfer is under way.

Grawitz: There you are. Then you will be under my orders as a physician at any rate and all matters will have to go through my office, otherwise the situation would be unbearable.

Rascher: But I am under the orders of the Ahnenerbe! Am I to report to you, too, what I have to report to the Ahnenerbe?

Grawitz: Certainly! At least a copy on all medical matters has to be sent to me for my information. For it is an unbearable situation to have a non-physician, such as Standartenfuehrer Sievers, inform me on medical matters if he does not have the adequate special medical education. I have nothing against Sievers. Well, yes, I know you are of the Ahnenerbe. I don’t say anything against your work for the Ahnenerbe, but I want you to work with the Ahnenerbe for the Reich Physician. I shall also write to Brandt on that matter.

Poppendick: Well, I already had to ask Standartenfuehrer Sievers several times to come to me to receive information. In the long run all medical matters wind up with us, anyway.

Grawitz: You see, this is the point! When the Reich Leader SS does not understand a medical matter clearly he hands the matter over to me, anyway.

Rascher: Of course, I am grateful for every kind of help, but I believe that I am primarily under the orders of the Ahnenerbe.

Grawitz: Certainly not when you are a member of the Waffen SS. I am able to be of much use to you through my knowledge and I shall inform Brandt to that effect. It isn’t that I bear a grudge against you or your work, but all things have to follow their course. Don’t be afraid, scientific thefts don’t occur with us. As I know, you have to acquire the right of giving lectures at universities as a qualified academic teacher under Pfannenstiel. And you will need support. Do you want to be supported by me?

Rascher: Of course, I thank you most obediently. Where I need support, I gladly accept it.

Grawitz: Well, we shall wait then with the memorandum until you have a few hundred cases, then we shall continue. Of course, I would not like the Reich Leader SS to believe that I want to impede you. But if something has not yet been proved to a great extent, we cannot distribute anything to the troops that might spread uncertainty among the responsible authorities!

Everything may be true for freezing by water, but we don’t have that in the Waffen SS. So you agree to wait with the distribution of the memorandum.

Rascher: Gruppenfuehrer, anyway it is entirely your affair, whether the memorandum is issued now, as you are responsible for it. I composed the memorandum on the basis of these few cases of dry freezing, because the Reich Leader SS pressed for its publication. In composing the memorandum, I was fully aware of the necessity that many experiments still have to be carried out, and I also submitted this view on the occasion of a discussion with the Reich Leader SS in Dachau. But the Reich Leader saw the results in Dachau and in wanting to help the troops ordered the memorandum to be drawn up.

Grawitz: In composing a memorandum or in any other scientific work you should not let anybody press you, not even the Reich Leader SS, that will never do! Well now, you’ll send me a copy of all your medical correspondence with the Ahnenerbe, and you’ll no longer write directly to the Reich Leader SS in medical matters but write to me, as it comes to me anyway. Will you do that?

Rascher: I’ll have to discuss the matter with Standartenfuehrer Sievers first, this comes too much as a surprise.

Grawitz: Well, I shall send you a copy of my letter to Dr. Brandt so that you can get a clear picture. I am very pleased to have established such a close contact with you.

This is a certified true copy.

LETTER FROM RASCHER TO HIMMLER, 17 FEBRUARY 1943, AND
SUMMARY OF EXPERIMENTS FOR REWARMING OF CHILLED
HUMAN BEINGS BY ANIMAL WARMTH, 12 FEBRUARY 1943

Munich, 17 February 1943

To the Reich Leader SS and Chief of the German Police Heinrich Himmler

Berlin SW 11, Prinz Albrecht Str. 8

Dear Reich Leader,

Enclosed I present to you in condensed form a summary of the results of the experiments made in warming up people who have been cooled off by using animal heat.

Right now I am attempting to prove through experiments on human beings that it is possible to warm up people cooled off by dry cold just as fast as people who were cooled off by remaining in cold water. The Reich Physician SS, SS Gruppenfuehrer Dr. Grawitz, doubted very much that that would be possible and said that I would have to prove it first by 100 experiments. Up to now I have cooled off about 30 people stripped in the open air during 9-14 hours at 27°-29°. After a time corresponding to a transport of 1 hour, I put these subjects in a hot bath. Up to now every single patient was completely warmed up within 1 hour at most, though some of them had their hands and feet frozen white. In some cases a slight fatigue with slightly rising temperature was observed on the day following the experiments. I have not observed any fatal results from this extremely fast warming up. I have not so far been able to do any warming up by “Sauna” as ordered by you, my dear Reich Leader, as the weather in December and January was too warm for any experiments in the open air, and right now the camp is closed on account of typhoid and I am not allowed therefore to bring in subjects, for “Sauna” experiments.

With most obedient greetings and sincere gratitude, and

Heil Hitler!

Yours very devotedly

Rascher

Secret

Experiments for rewarming of intensely chilled human beings by
animal warmth

A. Purpose of the Experiments

To ascertain whether the rewarming of intensely chilled human beings by animal warmth, i. e., the warmth of animals or human beings, is as good or better than rewarming by physical or medical means.

B. Method of the Experiments

The experimental subjects were cooled in the usual way—clad or unclad—in cold water of temperatures varying between 4° C. and 9° C. The rectal temperature of every experimental subject was recorded thermoelectrically. The reduction of temperature occurred within the usual span of time varying in accordance with the general condition of the body of the experimental subject and the temperature of the water. The experimental subjects were removed from the water when their rectal temperature reached 30° C. At this time the experimental subjects had all lost consciousness. In eight cases the experimental subjects were then placed between two naked women in a spacious bed. The women were supposed to nestle as closely as possible to the chilled person. Then all three persons were covered with blankets. A speeding up of rewarming by light cradles or by medicines was not attempted.

C. Results

1. When the temperature of the experimental subjects was recorded it was striking that an after-drop of temperature up to 3° C. occurred, which is a greater after-drop than seen with any other method of rewarming. It was observed, however, that consciousness returned at an earlier point, that is, at a lower body temperature than with other methods of rewarming. Once the subjects regained consciousness they did not lose it again, but very quickly grasped the situation and snuggled up to the naked female bodies. The rise of body temperature then occurred at about the same speed as in experimental subjects who had been rewarmed by packing in blankets. Exceptions were four experimental subjects who, at body temperatures between 30° C. and 32° C., performed the act of sexual intercourse. In these experimental subjects the temperature rose very rapidly after sexual intercourse, which could be compared with the speedy rise in temperature in a hot bath.

2. Another set of experiments concerned the rewarming of intensely chilled persons by one woman. In all these cases rewarming was significantly quicker than could be accomplished by two women. The cause of this seems to me that in warming by one woman only, personal inhibitions are removed, and the woman nestles up to the chilled individual much more intimately. Also in these cases, the return of complete consciousness was strikingly rapid. Only one experimental subject did not return to consciousness and the warming effect was only slight. This person died with symptoms suggesting cerebral hemorrhage, as was confirmed by subsequent autopsy.

D. Summary

Rewarming experiments of intensely chilled experimental subjects demonstrated that rewarming with animal warmth was very slow. Only such experimental subjects whose physical condition permitted sexual intercourse rewarmed themselves remarkably quickly and showed an equally strikingly rapid return to complete physical well-being. Since excessively long exposure of the body to low temperatures implies danger of internal damage, that method must be chosen for rewarming which guarantees the quickest relief from dangerously low temperatures. This method, according to our experiences, is a massive and rapid supply of warmth by means of a hot bath.

Rewarming of intensely chilled human beings by human or animal warmth can therefore be recommended only in such cases in which other possibilities for rewarming are not available, or in cases of specially tender individuals who possibly may not be able to stand a massive and rapid supply of warmth. As for example, I am thinking of intensely chilled small children, who are best rewarmed by the body of their mothers, with the aid of hot water bottles.

LETTER FROM HIPPKE TO HIMMLER, 19 FEBRUARY 1943, ON
FREEZING EXPERIMENTS IN DACHAU

The Inspector of the Medical Service of the Luftwaffe

File No. 55 No. 81038/43 (2 IIB)

Reich Leader,

The experiments conducted in Dachau concerning protective measures against the effects of freezing on the human body by immersion in cold water have led to results of practical use. They were conducted by the Stabsaerzte [Captains] of the Luftwaffe, Professor Dr. Holzloehner, Dr. Fink, and Dr. Rascher in cooperation with the SS, and are now finished. The results were reported upon by those who worked on them during a conference on medical problems arising from distress at sea and winter hardships, on 26 and 27 October 1942, at Nuernberg. The detailed report on the conference is at present in state of preparation.

I thank you most gratefully for the great assistance that the cooperation of the SS has meant for us in conducting the experiments, and beg you to express our thanks, too, to the commander of the Dachau camp.

Heil Hitler!

REPORTING ON DRY-FREEZING EXPERIMENTS IN DACHAU

Dr. med. Sigmund Rascher

[4 April 1943]

To Herr Oberregierungsrat SS Obersturmbannfuehrer Dr. R. Brandt

Berlin SW 11, Prinz Albrecht Strasse 8

Much esteemed Obersturmbannfuehrer!

The question of the saving of people frozen in the open air has in the meantime been cleared up, since, thank goodness, there was once again a period of heavy frost weather in Dachau. Certain people were in the open air for 14 hours at -6° C., reached an internal temperature of 25° C. with peripheral freezings, and were all able to be saved by a hot bath. As I said: it is easy to contradict! But before someone does so, he should come and see for himself. Moreover, a report about freezing in the open air will be sent to the Reich Leader in the next few days.

With best wishes,

Heil Hitler!

Yours gratefully,

LETTER FROM RASCHER TO KEINDL, 28 APRIL 1943, ABOUT PREVIOUS FREEZING EXPERIMENTS CONDUCTED AT SACHSENHAUSEN

Dachau 3K, 28 April 1943

Obersturmbannfuehrer!

By order of the Reich Leader SS, I have been conducting freezing experiments on human beings in the Dachau concentration camp for more than a year. Today I learned from an experimental subject that I was not the only one conducting these experiments, but that, on the contrary, already in October and November 1938, similar experiments were conducted in the Sachsenhausen concentration camp. SS Hauptsturmfuehrer Dr. Samenstrang is said to have frozen experimental subjects—that is prisoners—in cold water, and subsequently revived them by means of warm water or hot compresses. As I was to work out and have worked out a prescription for the Waffen SS for the resuscitation of frozen persons (for the campaign in the East), knowledge of all preliminary experiments in my field of work is of great importance for me.

I therefore request that if possible you let me know what kind of experiments were conducted in your camp, and, if possible, what results were obtained in connection with these experiments.

As you might not know anything about me, please make inquiries about me, if necessary, either at the Personal Staff of the Reich Leader SS (Obersturmbannfuehrer Baumert) or from the Commander of the Dachau concentration camp, SS Sturmbannfuehrer Weiss.

Yours sincerely

Heil Hitler!

LETTER FROM RASCHER TO SIEVERS, 17 MAY 1943, CONCERNING,
A CONFERENCE WITH GEBHARDT ON FREEZING EXPERIMENTS

Dr. med. Rascher, SS Hauptsturmfuehrer

Dachau 3K, 17 May 1943

Dear Standartenfuehrer!

The following contains a short account of my report to SS Gruppenfuehrer Dr. Gebhardt.

On 14 May 1943, I reported to SS Gruppenfuehrer Prof. Dr. Gebhardt at Hohenlychen. I had hardly arrived, when SS Gruppenfuehrer Dr. Gebhardt asked me in a very loud voice to explain how I dared to submit specialist medical reports directly to the Reich Leader SS (he was referring to the treatise on “The Cooling of Human Beings Outdoors”). I actually did not even get a chance to speak and practically couldn’t reply anything. Then, when I tried to reply, Prof. Dr. Gebhardt said that if I wanted to defy him, my train would be leaving for Berlin at 3 o’clock. When I was finally given the opportunity to speak I was able to point out to Prof. Dr. Gebhardt that the report in question was not meant to be a strictly scientific work, but simply was a short information for the Reich Leader SS on the results of the experiments conducted up to now. Dr. Gebhardt had taken the view that the report was unscientific, and if a student of the second term dared to submit a treatise of that kind, he would throw him out. Later on I was able to tell him that of course all the physiological-chemical experiments that could be carried out in Dachau with the available instruments had indeed been conducted. Whereupon Dr. Gebhardt replied: “I can imagine that you did a lot of work; one can tell it from this job. If I had not believed that you did a lot of work, I would not have asked you to come at all.”

In addition Dr. Gebhardt said that he intended to merge all the groups of physicians working independently within the SS, since that would suit the Reich Leader SS much better than individual people working on their own. Besides that, he said that I somehow ought to learn university methods of working since very likely I did not yet have the proper training. He suggested that it was necessary for me to get out of Dachau since there I was quite left to myself and had no guidance whatsoever; that since I intended to enter upon a university career, I would by all means have to complete the training of a university assistant first. He further said that all those SS physicians, who are qualified to enter upon a university career, had the duty to do so. Upon my reply that for that reason I was already in touch with Professor Pfannenstiel, Professor Gebhardt replied that these matters ought to be processed by a centralized agency. In future it would not do that I send any reports directly to the Reich Leader SS, but that further reports to serve their purpose would have to be transmitted through him to the Reich Leader. If the report had reached a suitable stage, he would first inform the Reich Leader SS, and then go to see the Reich Leader SS together with me. Finally Dr. Gebhardt asked me to give him data on my personal and scientific career to enable him to make further arrangements. He requested me to call again in the afternoon.

When I called in the afternoon, I was, as in the morning, accompanied by SS Hauptsturmfuehrer Dr. Fischer. This time Dr. Gebhardt was extremely amiable. He asked me whether I now agreed with his arrangements; it would be by far the best I could do, if I joined him. I should not worry, but just continue my work in Dachau, until I had finished my jobs. Later, one would see what was to be done for the future. Upon my question, what it was all about, and who was my superior, whether the Reichsarzt SS, SS Gruppenfuehrer Dr. Grawitz, who had come for an inspection several days ago, the Reich Leader SS, as he personally had promised me, or the Ahnenerbe, of which I had been a member for years, Dr. Gebhardt suggested that all that will be straightened out. Just trust it to me. But I’ll need your curriculum vitae soon, since I have to report to the Reich Leader SS on 23 May.

May I ask you, Standartenfuehrer, under whom I am actually working? Under the Reich Leader SS, the Ahnenerbe, the Reich Physician SS or Dr. Gebhardt? Dr. Gebhardt has already asked me why I am not a member of the Waffen SS. Upon my answer that Dr. Hippke does not like to let me go, he declared that I was too able for him to let me go. Standartenfuehrer! If the same tug of war starts in the Waffen SS as has been going on between Luftwaffe and the SS, I’d rather do without a transfer to the Waffen SS. I was promised that I would continue to work under the Reich Leader SS or under the Ahnenerbe. But I cannot serve several masters at the same time. Of course I am convinced that SS Gruppenfuehrer Prof. Dr. Gebhardt has the best of intentions. His assistants are enthusiastic about him. If I am compelled to ask Prof. Dr. Gebhardt’s advice each time I am going to start a new experiment, I will get so much involved in the academic routine that I won’t even be allowed to experiment with such a method as rapid resuscitation which overthrows all the established clinical experiences because the results contradict Prof. Dr. Gebhardt’s methods which are based upon centuries-old clinical experiences. Also the cooperation with Professor von Luetzelberg would thus come to an end, as these experiments are from the very start contradictory to the hitherto recognized clinical experiences. I think, this arrangement would stop everything that really ought to be experimented.

I pray you with all my heart, Standartenfuehrer, to handle this affair in such a way that Prof. Dr. Gebhardt, who is a very close friend of the Reich Leader SS does not become my enemy. I think that Prof. Dr. Gebhardt can and will be an extremely disagreeable adversary. Before I get into trouble with him, I would rather resign my job and ask for an immediate transfer to the Luftwaffe for combat service. I therefore ask you again to deal with this affair with as much circumspection as it actually requires, because in addition I am convinced that Prof. Dr. Gebhardt (apart from his personal ambition) really has good intentions.

Very respectfully yours and

Heil Hitler!

Yours very devotedly

LETTER FROM RASCHER TO NEFF, 21 OCTOBER 1943, CONCERNING
DRY-FREEZING EXPERIMENTS

Dr. S. Rascher

Dachau, 21 October 1943

Dear Neff:

Your letter dated 11.10 reached me here on 15.10. First of all many thanks for your decision to write such a detailed letter. I really was very pleased about it. To come right away to the affair concerned: I am very sorry to hear that you are being bullied, especially as there exists no reason at all for it. Please let me know the name, rank, and address of your commanding officer because I most certainly will take the matter up. There is no purpose at all in your getting stuck there. Finally I too know how the general condition of your health had been, when you were still here, and I also am able to judge that you cannot go through heavy infantry training. I am glad that you have become accustomed to the ideals of the place and I am convinced that you would be glad to go to the front. But on the other hand, I believe that I need you more urgently than you are needed at the front. As a matter of fact I need you for the following: From the Reich Research Council [Reichsforschungsrat] I got the order to carry out open country freezing experiments and I think they will take place on the Sudelfeld. Now I need urgently a most reliable man, acquainted with the material, and that is you in this case. During the next few days I will go with Sievers to the Fuehrer’s Headquarters [Fuehrerhauptquartier], and report there in this sense, and will let you know immediately.

I expect your notice soon, and remain until then with sincerest comradely regards,

Your old chief,

[Initialed] R.
