  Department of Justice

  HOLC Building

  Gentlemen:

  I am writing in support of the application of Dr. Sidney Weinbaum now at McNeil Island, for parole.

  I have known Dr. Weinbaum for nearly thirty years. He was an undergraduate student at the California Institute of Technology while I was a graduate student, and we attended some classes together. I did not become very well acquainted with him until 1929. At that time he had lost his job, just when the young man who had been appointed my assistant had been drowned in the sinking of the steamer San Juan. Sidney Weinbaum was given appointment as my research assistant, and from 1929 he continued for nearly fifteen years to serve in this capacity. He completed work for the Ph.D. degree in physics, under my direction.

  Dr Weinbaum is a man of considerable ability, and with extensive training in the physical and mathematical fields. He served as a very effective collaborator with me in various investigations in the field of fundamental research, including quantum mechanics and the determination of the structure of crystals with x-rays.

  Although I have not known Dr. Weinbaum intimately, except in this professional capacity, where I had day-to-day contact with him, I may say that I have always had confidence in him as a reliable and thoughtful person. So far as I am aware he has not been accused of any subversive activities that involve his access to classified material. I do not know enough about the circumstances attending his arrest, trial, and conviction for perjury to feel that I understand this matter. I may say, however, that I consider Dr. Weinbaum to be a trustworthy and loyal American citizen, and it seems to me that the events leading to his conviction must have resulted from circumstances that strained him beyond his control. I do not think that Dr. Weinbaum is a man of strong will. I think, however, that he is a good man, and I hope that it will be possible to give him parole.

  Sincerely yours,

  The Honorable Dean Acheson

  Washington, D.C.

  My dear Sir:

  I have learned recently that Stephen H. Fritchman, minister of the First Unitarian Church of Los Angeles, was denied a passport, when he had been invited to address the Australian Unitarian Churches, in celebration of the hundredth anniversary of the introduction of Unitarianism into Australia.

  I am writing to express my strong feelings about the denial of this passport. I myself suffered great harm as a result of the denial of a passport to me this spring, when I had been invited by the Royal Society of London to take part in a special discussion meeting of the Royal Society on the structure of proteins, on 1 May. This harm has been diminished only in part by the subsequent issuance of a passport to me, permitting me to go to France and London to discuss scientific questions with scientists in these countries. No explanation of the denial and later issuance of a passport to me was given by the Department of State, and I conclude that a mistake was made by the Department when the passport was denied to me initially.

  I feel that a similar mistake has been made in the case of Mr. Fritchman. I have known Mr. Fritchman for several years. I consider him to be a great man. He is one of the most honest, forthright, straightforward, and high-principled men that I have ever known. He is an honor to the United States of America - the world would be a great world indeed if one percent of its people were comparable to Mr. Fritchman.

  Is the United States of America, through its passport policy, now going to interfere with religion in the way that it has interfered with the progress of science? Is the passport policy that has been pursued, and apparently is still being pursued, designed to suppress those conscientious ministers of the Gospel who are working for the welfare and happiness of human beings throughout the world?

  I sincerely trust, for the sake of the United States of America, that the precedent that has been set by the Department of State in my case can be followed, and that Mr. Fritchman will be given his passport.

  Yours truly,

  First Unitarian Church

  2936 West Eighth Street

  Los Angeles 5, California

  Dear Mr. Fritchman:

  I have come across your letter of 22 July, which awaited me for two months, until I returned from Europe.

  I was sorry that it seemed necessary to me to reply to your cable by not accepting your kind offer to me to take part in the Forum this year, and to speak this fall. I found it necessary to leave for Europe on 15 July, with only four days' notice - I had not expected that the Department of State would reverse its decision about my passport. I had, in the meantime, agreed to do work during the summer (especially the revision of a book, which the publisher wished to put out in a second edition), and the trip to Europe necessitated my postponing this work. On my return to Pasadena I had not only this job to do, but all of the accumulated work of the summer, at the Institute; and I am sorry to say that I am still overwhelmed.

  I feel very sympathetic to the Unitarian Church, however, and I should like to do my part. The letter of 22 July suggests that I be a speaker on the Forum during this season, and specifically that I speak on a second Friday night in any month from January through May, 1953.

  I recognize that you probably have arranged your schedule completely. I, too, have some engagements - in particular, I have agreed to go to Belgium for a week, probably the first week in April, so that April would be ruled out for me.

  Would you pass on to Mr. Mahoney the suggestion that if there is still an open date, I should be glad to appear on the Forum, provided that it does not conflict with an engagement already made. I am not suggesting days, because so far as I know now any second Friday from January to May, except April, would be satisfactory to me.

  I was shocked indeed to learn about the refusal of a passport to you. I have written a letter of protest to the Secretary of State. It seems to me to be a more reprehensible action, on the part of the government, that was the refusal of a passport to me, a scientist.

  Mr. Fritchman Page 2 4/11/52

  There is one bit of information that I am happy to pass on to you. Professor Weber, of the University of Tübingen, extended to me a tentative invitation to come to Germany next summer. He said that he was hoping to arrange a German-American conference on the physiology and structure of muscle, and that he was going to ask the Unitarian Service Committee to bring me to Germany, in order to take part in this conference. I was greatly impressed by Professor Weber, when I met him in Paris this summer and I hope that this arrangement can be made.

  With the expression of my sincere admiration for the forthright stand that you have continued to take on the important questions of the day, I am

  Sincerely yours,

  To: Professor Pauling From: Walter Schroeder Date: November 6, 1952

  I would like to present a resumé of amino acid analyses of gelatin and collagen as they are to be found in recent literature. The data are recorded in the attached table.

  Sources and Presentation of Data

  The date listed under “Neuman” are taken from papers by Neuman (Arch. Biochem., 24, 289 (1949)) and Neuman and Logan (J. Biol. Chem., 184, 299 (1950)). In these papers, complete analyses are listed for 4 gelatins, 12 collagens, and 6 elastins from various mammalian, avian, end marine sources. In summarizing these values for the attached table, the elastins as well as the marine gelatin and collagen have been omitted; the marine materials differ appreciably in certain amino acids. The table lists the averages from 3 gelatins and 11 collagens and also the extreme values which Neuman gives for proline, hydroxyproline , and glycine. Neuman has made these analyses in the main by microbiological procedures but has also used chemical and colorimetric methods. Hydroxylysine is assumed to be 1 g. per 100 g. protein.

  The data listed under “Tristram” are his compilation (Adv. Prot. Chem., 5, 143 (1949)) of the results of Chibnall and of Bowes and Kenten.

  The table also includes a calculation of the residue percentage accounted for by proline, hydroxyproline, and glycine in the two proteins and a few other values which are to be found in the literature for these three amino acids.

  Comments

  It seems reasonable to assume that the data may be in error to ± 5 to 10 percent of the quantity determined. In very few instances is this conservative estimate of error exceeded by the differences which are to observed whether one compares Neuman’s and Tristram’s values for the two proteins individually or whether one compares the two proteins with each other. The concordance of the results is very gratifying in view of the fact that the results from more than 15 samples are being compared. It should also be mentioned that in these analyses essentially all of the nitrogen and weight of the proteins is accounted for. A few scattered values from the literature agree well; in the case of hydroxyproline and glycine but those for proline are considerably higher. The latter were obtained by the Bergmann school by precipitation methods and are suspect for this reason.

  It is reasonable to conclude that the published analyses of gelatin and collagen give a very good picture of the amino acid composition of these proteins and, furthermore, that these proteins do not differ appreciably in their amino acid make-up. The average of all data given by Neumann and Tristram for proline, hydroxyproline , and glycine in both proteins is as follows:

  [Data Table]

  In view of this rather extensive body of data, it is doubtful that it would be desirable or worthwhile for us to embark on a program of determining the amino acid composition of gelatin and collagen by ion exchange methods. In order to obtain definitive results, the efforts of two workers for at least six months would be required. If our results should differ from the data which have been presented, it would probably require much more work in order to determine the source of the differences.

  Dear Dr. Pauling: Sunday, Nov. 9

  I don't know how much of what is currently going on around here you did not get to talk over when you were here, so some of things in this newsletter may be old stuff, but anyway, here goes. Francis Crick has been working over an idea he has, and has written a letter to "Nature" entitled "Is α-Keratin a Coiled Coil?". This has to do with a central α-helix surrounded by some more of the same which are helical helices, with pitch just right to explain the meridional reflections which the α-helix does not. Max sent it to the editor with a covering letter requesting high speed publication, so he must think it's pretty hot stuff, although Bragg apparently isn't too keen on the idea. I must confess that I haven't looked into the matter very thoroughly, mostly because it's rather hard to follow Crick's mercurial arguments, and anyway, the whole thing isn't on a very quantitative basis as yet.

  The London meeting celebrating the 40th anniversary of x-ray diffraction was most interesting. Bragg gave the final paper, concerned with his & Max's progress with hemoglobin. They have done ever so much more than described in their Proc. Roy. Soc. paper, the one with the trains, and now have an array in the (hCl) plane going up to about h=12, each line of constant h having a possible curve, or its negative, following the molecular transform. As yet they have no form giving information between the h lines, thus the ambiguity for each line, and a total number of possibilities of 2h . Max isn't quite satisfied with the accuracy of some of the data, so the drawing of the nodes and loops is considered provisional. They have not, so far as I know, made any of the projections for the possibilities which they think are more probable. Max rediscovered a missing shrinking stage last week, and this may give more useful data. I am photographing crystals of sheep metHb which I grew myself, starting with the sheep. This, it is hoped,will give some values between the h-lines.

  I have been talking over with Prof. Sutton the possibility of extending the interatomic distance tables to include x-ray results. We agreed that it was a good idea, and now have to decide where to draw the line. Furthermore he has to clear my participation with Kathleen Lonsdale, who once had a student working on it, but said student didn't really do any work, and wasn't reliable anyway, nevertheless she must be allowed to give her release. Nothing is straightforwardly simple in this country.

  With regard to next year, I am still interested in the Berkeley proposition, but it seemed to me that in his last letter Prof. Stanley wasn't too encouraging. It may just be his way of saying things, so I shall be very interested in any impressions you have had in your talks with him about me. If the Berkeley job could develop into something permanent, that would of course be very nice, and if it definitely could not, I don't think that I would be too interested.

  I have also been doing some more work on Dyer's compound, his cysteylglycine sodium iodide with the non-planar peptide group. I have a structure with everything orthodox, but am now faced with the prospect of calculating the F's by hand (they are complex). This project may come in handy, however, on those long dark winter evenings.

  Peter, who may have written about his bathtub arrangements, has a standing invitation to use our bathroom here at the house, but he hasn't taken advantage of it yet. I do not think that this means that he has not yet taken a bath, as the days have been relatively warm until quite recently. We were all going to throw a party here, on the 5th, in case the election came out right. So, in place of the party the prospective

  Dear Dr. Low:

  I am pleased that you are publishing a note on the 4.4-residue helix. We evaluated the coordinates for it a short while ago, and have been making some calculations of the strain energy, etc. Also, I tried to find out why we overlooked it in our earlier work, apparently it was simply overlooked, at the time when we were attempting to discover helical structures of this sort by the analytical solution of simultaneous equations (trigonometric ones, of course), defining the bond angles and the distances. We worked very hard on this job, for over a year. It is evident now that this mathematical method is not the best one for finding structures of this kind.

  I am sorry that I cannot send you a reprint of my Phi Lambda Upsilon Lecture but our supply of them is exhausted.

  As to the Bamford X-ray pattern, the repeating unit with fiber axis 43.2 A. seems to me to be a 29-residue 8-turn unit. I think that the Courtsulds people feel the same way, although, of course, they are not sure about our α helix. I may mention that Dr. Yakel here made a preparation of poly- -methyl-L-glutamate with a different X-ray pattern from the earlier one that we had (which corresponded to 18 residues in 5 turns). The new fiber is not hexagonal, and I am not sure what its identity distance is.

  It seems to me to be wrong to emphasize the difference between an 18-residue 5-turn, an 11-residue 3-turn, and a 29-residue 8-turn α helix, as Bamford has done in one of his papers. All of these are included within our original description of the α helix. The coordinates of the 18-residue 5-turn helix were presented, as an example. In our discussion both this structure and the 11-residue structure ware dis-

  Dr. B. W. Low: Page 2 November 10, 1952

  cussed, and It was pointed out that a little range of values of number of residues per turn could be accepted.

  I feel sure that there are at least two, probably three, and perhaps more different modifications of fibrous poly- -methyl-L-glutamate, all, however, based upon the α helix.

  Sincerely yours,

  Dear Jerry:

  I thank you for sending your letter, with mention of Crick's letter to Nature "Is α-Keratin a Coiled Coil?".

  I remember that when I was in Cambridge Crick asked me if I had thought about the possibility of α helixes twisting around one another, and I said that I had - I don't remember that we said any more about the matter. In fact, I have been trying to account for the x-ray data, etc, for the α -keratin proteins on this basis, and after considerable work felt that the answers had been found. Corey and I sent a paper to Nature about two months ago, on this subject, but it has not yet appeared, I wrote to the editors last week, asking when it would be published. We are writing several detailed papers about these compound helixes now.

  I didn't have a chance to say anything to Stanley about the Berkeley job, when I was up there, I judge that things are not too promising, from what you say. I have accordingly just written to Professor Stanley J. Cristol, at the University of Colorado, Boulder, Colorado, recommending you for appointment there. They want a man who would accept appointment to the staff and also be willing to serve as Department Chairman, for a limited term. They are interested only in men eligible for the rank of Associate Professor or full Professor. I think that Colorado is a fine place, and that this would be a good job for you — the University is in Boulder. Why do you not write to Cristol, giving him detailed information about your career.

  I hope that you finish up the cysteyl glycine sodium iodide structure.

  I'm glad to learn that you have a good house. We were disturbed to know that you were having trouble. I know that housing is a problem in Cambridge.

  21 November 1952

  Dr. Albert Szent-Gyorgyi

  Laboratory of the Institute for Muscle Research

  Marine Biological Laboratory

  Woods Hole, Massachusetts

  Dear Dr. Szent-Gyorgyi:

  I am very pleased to have your letter of 8 November 1952. I shall be especially pleased, of course, if your nomination for the Nobel Prize in Chemistry for 1953 were to be successful; but in any case I am grateful to you for expressing such a high opinion of my work.

  First, let me say that I am not responsible for the discovery of the hydrogen bond. I think that some of my work on the hydrogen bond was of some importance, but it is my opinion that the credit for the discovery of the hydrogen bond belongs to W. M. Latimer and W. H. Rodebush, both of whom were then at the University of California (Latimer is still there, and Rodebush is at the University of Illinois). Their paper in 1922 was the first one in which the hydrogen bond was described in a clear way, with a discussion of its importance. There had been rather vague suggestions made by other people, during the preceding ten years.

  I think that my own most important work was done during the period 1928 to 1932. It involved the discovery of fundamental principles about the nature of the chemical bond and the configuration of molecules. Many applications of these fundamental principles have been made, of which the application to proteins is without much doubt the most important. The application to proteins has included work on hemoglobin, especially study of the magnetic properties and relation to the structure of the molecule in the neighborhood of the iron atoms, and also, more recently, the work with Corey on the configuration of polypeptide chains in proteins.

  I enclose a nearly complete bibliography, and a statement, about my contributions to science, including some quotations and references to the original papers. I also enclose some of the original papers. I am sorry to say that I have completely exhausted the reprints of some of these.

  Dr. Szent-Gyorgyi Page 2 21/11/52

  The bibliography that I am sending is just a copy of a standard bibliography that we have prepared. The statement about the researches is, however, one that I have written just for you in answer to your letter. The wording is not identical with that in any publication or document.

  You may be interested to know that Professor Corey and I have sent, about two months ago, a short paper to NATURE, in which we describe structures of the α-keratin proteins that are somewhat improved over our earlier ones. The new structures involve exactly the α helix, which we described before. However, instead of the α helix having a straight axis, as it has in the synthetic polypeptides, some of the molecules are compound helixes - an α helix whose axis is itself a helix. The α-keratin proteins consist of cables, each of which involves seven α helixes - a central one and six others that twist slowly about it. Moreover, these cables are piled together, and the interstices are filled with additional α helixes, which have a slight twist in order to fit in. I may say that I think that actin consists of individual α helixes (which fill up the interstices in actomyosin), and that myosin consists of the seven-strand cables. There is a good bit of evidence in support of these ideas.

  I hope that you will come to see us in Pasadena one of these days - it has been a long time since you have made a trip out here. If it turns out that you are coming to Los Angeles for some purpose next year, as I hope you will be, we should be very pleased to have you visit us - perhaps you and Mrs. Szent-Gyorgyi could be our guests. If you come during the academic year, I hope that you would find it possible to present a seminar talk again. If you are here in the summertime, I hope that you can chat with us about the structure of muscle.

  With best regards, I am

  Sincerely yours,

  Dear Mamma,

  Thanks very much for the letter. I enjoyed it. My room, like many English rooms, is yellow with black trim. I hung up the material Anita gave me for a lava lava, but it certainly needs something, Curtains would be very nice. I really need a picture, like your Picasso lovers or that Gaugin. I must try sometime to buy a Gaugin. It is very cold in my room. I cannot keep it warm, very drafty.

  I am very happy to be here. It is cold and wet, but no end of the plays and lectures and books and societies. I charge books and therefore can run up an immense bill. I ordered Eric Partridge's Dictionary of Slang for Pa. Probably cost a mint to send it over, in which case I'll send the Oxford D. of Americ Modern American Usage instead. Hard to find presents for women in this country.

  I think I shall probably put in a request for an increase in the original starting off sum of money I had. This was $50 + to keep me alive to 1 Oct. Well, I am still alive and the $50 was spent on blankets and sheets. It was to buy me a coat, 3 blankets, 4 70x40 sheets 13 ²/₆, $40. Well, anyway, I have blankets but no coat. I originally thought the 1^st monthly check for $125 was for sept, in which case I could buy clothes with it. But it was for October.

  I talked 6 weeks ago with Victor on the phone, but still have not heard from them since. I went to tea at Todds and danced with the youngest, and to lunch in Clare with Sir John L.J. and wife and daughter. He is very nice. I do not know what to do for Christmas. No invitations. I cannot afford to go to Paris or Wasers, but they won't allow me to stay in college and the Cavendish is closed for three weeks. I can live with Kendrews, but would like to do something different. Maybe Oxford. Can I just write to Dorothy and ask to stay a week? Maybe Rothschilds will come through.

  I had my first tea last Sunday. Reasonably good for a first attempt. I like Odile and Frances very much. That dark brown china of hers is German.
