  Dear Riley:

  I am writing to you because Dr. Corey end I have decided that there is the possibility (not, however, yet assured) that an appointment could be offered to Dr. Arndt, effective this summer or fall.

  If I remember correctly, both you and Dr. Arndt spoke to me about the possibility of his coming to this country. I believe that he wants to come here permanently.

  I should be pleased to have you give me your opinion of Dr. Arndt. Has he had experience in the determination of crystals - I believe not. I remember that he is a physicist, and I think you told me that he is a good man with apparatus. Do you consider that he is a hard worker?

  At the present time what Dr. Corey and I have in mind is that we might have him help us on making a radial distribution study of a number of nucleic acid preparations, and perhaps some other things.

  If we find out that the funds available to us will permit us to offer him an appointment, and if your recommendation seems to justify it, our appointment would be for one year. There is, however, a good chance that the appointment could be continued for a second year.

  With best regards, I am

  Sincerely yours,

  Linus Pauling:W

  P.S. The Editors of NATURE have now written me that our paper will appear in the 10 January issue - you no doubt will have seen it by this time. I have written them, saying that we were misled by their letter three months ago into believing that it would be given rapid publication. LP

  Dear Riley:

  I am writing now to say that we have found the error in our calculations of the radial distribution functions for the α helixes (1 and 2).

  I regret to say that the wrong azimuthal angle was used in locating the positions of some of the atoms in the structure. As a result some of the interatomic distances are wrong — usually by a few tenths Angstrom, but in some cases by as much as one Angstrom.

  We propose at some convenient time in the future to mention that this error has been made, without going into much detail about it. You may mention it, if you care to - perhaps you should let me check on the wording.

  With best regards, I am

  Sincerely yours,

  13 January 1953

  Dear Momma and Daddy and Crell,

  I came back today, just in time for [mail?] and now I am having a little Christmas all by myself. I had an immense pile of letters and magazines and a package. And I put out my greens and the nicely wrapped presents with them and put my cards on the mantel. I have not opened the things to eat, (except I cheated a little and had a date) the wrappings are grand. I got a book, Boswell in Holland, but I know not from whom. It came from Uromans. Sounds like Uncle Z.

  Last night in London, the night before in Brussels Bruxelles, (I don't know how you spell it in English.) Perhaps I ought to go see Daddy there. Really loud city. Parks and a ring, big boulevard. We stayed there a day. And two days in Frankfurt with George McManus. Do you remember him. Funny. He is about 40, works for the High Commission for Germany. Lives in a big house and has four full time servants. I do not think you should go back to Germany. It is too heart rendering. Rubble-rubble everywhere. The people are industrious and are making great progress though. Still, it is too tragic.

  I got your letter to Vienna forwarded to [Eisenery?]. We stayed there ten days. Fun, but too long for me to think I'll go alone in the future.

  Next summer I'll go to Sweden. I would like to float down the Rhine or something on a little raft and see you in Sweden. I fear the Myoglobin work will be so hot I'll have to stay here and work. Those dates are grand. Thank you very much for everything. Such an immense piece of fruit cake. I hope there is some left for the others, like you and Linda.

  I went to dinner at the Braggs with daughter Margaret, the night before leaving in December. She is too much the sophisticated Oxford undergraduate. Bragg is very nice.

  I got a letter from Tsang-Hsiang-San. He sent ten dollars for me to buy Planck for him which he should not have done. Address: 1820 N. Vista, L.A. 46. He did not get into Canada.

  There is now a bath tub here. I can bathe.

  Thank you, Crellin, very much for the New Yorker. I was hoping that some one would send it to me and I am glad you did. Thank you also for the Audio Engineering business. I am sorry it was so much work.

  14-1-53

  We all think you are hopping mad at Nature and rightly so. Evidently John & Francis finally got Bragg to write a letter to the editor telling him to get off the pot. But I guess by then he had already published. I was told a story today. You know how children are threatened "You had better be good or the bad ogre will come get you." Well, for more than a year Francis and others have been saying to the nucleic acid people at Kings "You had better work hard or Pauling will get interested in nucleic acids." I would appreciate very much a copy of "your" article. The MRC Unit would like one too. They are very interested. A couple of months ago Corey wrote Donahue or someone and said "'We' are writing another article..." With the we in quotation marks. I don't know if I should tell you all this. It is pretty amusing.

  Do you want more problems, or is it too late? I did not take the book with me on the trip. Could not do any work.

  My copy of the new International Table came. Very nice looking book. Ought to be for 8.40

  I don't really need pictures of the chairs. Just dimensions and angles. Daddy knows what would be needed to make one.

  I am working on sperm whale myoglobin. To determine the molecular shape. Stranded whales are the property of the Queen, but we have an agreement with her to get a piece of meat if one comes ashore.

  I might buy a kerosene heater.

  The nuts are wonderful. You are a darling Mamma.

  Bragg wants to know, and so do I, if you are coming to England after the Solvay Congress?

  Dearest family, thank you for everything.

  Much love,

  Peter

  Dear Herbert:

  I have just seen Dr. Rowen, who told me about some electron micrographs of nucleic acid fibers that yon have made. In particular, he said that you found, from the length of the shadow, that the molecules are about 20 A in diameter.

  Professor R. B. Corey and I have written a paper on the structure of the nucleic acids, which will appear in the February issue of the Proceedings of the National Academy of Sciences. Our structure is a completely detailed one, with all atoms precisely located, except that the purine and pyrimidine bases can be attached essentially at random.

  It is important in our argument that we know that the molecules are 20 A in diameter. We have quoted your 1948 work, and work of Ogston as leading to this value from physical chemical data. Also, we have referred to a paper by Williams, showing by electron micrography that the molecules are roughly this diameter. I think that we should probably refer to your electron micrographs. If you think that we should, will you give ne some information about your results, and a statement as to how we should refer to the work — perhaps it will be published before the end of January, and the reference could be given; if not, we can refer to the journal with the statement "in press."

  Our structure accounts nicely for the principal features of the x-ray diagrams. I have been tempted to think that all nucleic acids have the same fundamental structure.

  With best regards, I am

  Dr. Jerry Donohue

  Cavendish Laboratory

  Cambridge, England

  Dear Jerry:

  The holidays and various activities have kept me from answering your letter of 16 December until now.

  I asked Yakel to check over the calculations of the radial distribution functions for the a helix, and he has done so. He has reported to me that the inter-atomic distances that were used seem to agree with those that he has calculated, to within about 0.1 A. The coordinates that were used in the calculations are, in fact, not those given in our published table (which refers to a 3.6—residue helix), but those obtained about a year earlier. They correspond to a 3.67—residue helix - the helix with 11 residues in 3 turns.

  I think that the smoothing function that we used was one that I devised on the basis of information that you gave me. It involved spreading each point out over about 0.5 A to either side. I think that it is in between yours for B = 2 and B = 4. I sent details about our smoothing function to Riley, and it is likely that it does not differ much from the one that he used. It is not clear to me whether the difference between our calculated curves and yours (and Riley's) is due to a difference in the coordinates, or to something else. Perhaps we missed the double peak at 5 A for β carbon 2 because of an error in one of our points.

  Yakel, Schatz, and Rack have completed their work on the cylindrical distribution function. They have evaluated the cylindrical distribution function for a keratin and also for collagen from the experimental fiber diagrams, and they have evaluated the cylindrical distribution function for the a helix, using the coordinates for the 3.67-residue helix as the starting point. There is only rough agreement between the theoretical function and the experimental function for a keratin. There is of course, disagreement for collagen.

  I expect that you have seen our article in NATURE, on the a-keratin proteins. We have made more detailed calculations, but have not yet written the material up for publication in the PROCEEDINGS.

  Did I tell you that Corey and I have sent a paper on the structure of nucleic acids off to the PROCEEDINGS for publication? It will appear In the February issue.

  As to Carlisle, I went over his material on ribonuclease with him and Bernal this summer. I reached the conclusion that the Fourier diagrams that he obtains, and adduces as evidence against a helixes and in favor of a ribbon structure, are pure artifacts - that there is no justification for assuming the signs of Fourier terms in the way that he does. There is, of course, the possibility that

  Dr. Donohue Page 2 20/1/53

  I misunderstood the argument that he presented, but I do not think that I did.

  I hope to see you in Cambridge about 6 April - I plan to stop off for the weekend while on the way to Brussels.

  With best regards, I am

  Sincerely yours,

  Dear Linus:

  In reply to your letter of January 15, the paper "The Electron Microscopy of Sodium Desoxyribonucleate" by H. Kahler and B. J. Lloyd, Jr. is in press in Biochimica and Biophysica Acta. Enclosed is an abstract presented before the Electron Microscope Society.

  In this paper we conclude that the diameter of nucleic is 15 + 5 Ǻ. Most of our measurements were actually within the range of 15 + 2 Ǻ, but there is some uncertainty about the exact place where the shadow ends. An arbitrary decision has to be made in making the measurement, and since this decision made lead to a systematic error of a couple Ǻ we leaned backwards and simply put a round figure 5 Ǻ as the overall error. In any event, I would be surprised if the diameter is greater than 20 Ǻ. Our photographs have one important advantage over those of Williams in that the fibers tend to lie in a flatter position on the substrate film, whereas in his technique most of the fibers are partly off the film due to the freezing process. However, it was very satisfying to find that we both got the same value in completely independent determinations.

  I am very much interested in your paper and should like to receive a reprint as soon as possible.

  With best wishes.

  Sincerely yours,

  Herbert Kahler

  Dear Mamma,

  I still have a rather poor cold, and I do not know if I can ever get rid of it. The English remedy is to drink rum in hot milk.

  I have eaten all the dates and the candied walnuts. You are a darling mamma. They were very good. I am going to save the fruit cake, or I hope so. It is grand. I gave a piece to my little Danish girl friend the other night.

  I am interested in two things. (1) Does Daddy have Partridge, Eric, A Dictionary of Slang yet? If not I shall send it, as I now have a copy. It is lots of fun. (2) I want those chair measurements. I have now found a joker to make them. I need the angles & lengths and the iron diameter. And a couple of seats. Can you get them sent to me from New York.? If leather were nice & cheap, I might get a leather one here. But it is not.

  I am still mad at Rothschild's. Not a word. I was thinking about writing a letter in the Boswell-Eghiton fashion, but I guess it is a no go. I am not sure quite what to do.

  I am dickering for an overcoat. I have a duffle coat, but am looking for an overcoat. I hope to be successfull.

  I am quite happy with my lamb skin lined boots. The look very nice & are warm. The wool socks I bought in September are now shrunk so I cannot get them on. There is no way to get my wool things washed. I'll have to do it myself.

  I love you,

  Peter

  I have sent letters & cheques to 1. J. dyman Eng.

  I received an excellent letter from Mariette. Sounds like a fine girl. She might be completely grown up at the present rate continues by the time I am grown up, the rate of which is rather uncertain. I must write a letter to her.

  Mamma, you darling, my package came. Thank you very much. I have probably already written you about it. The [Springers?] are superb. They arrived excellent. The dates are very good; I had had some dates a little while ago; and the nuts I like. They disappeared to quickly. I like the sweater. It is a lonely color. For indoor wear.

  Is Linda coming to see me?

  The Daffodils are now blooming furiously. There are immense quantities in the market. Wild wood daffodil, are 9d a dozen. It has become very cold. I wear my duffel coat and my lambskin boots. I also have a cold, which I expect will last until summer.

  I wish Jim Watson were here. It is rather dull now. Nothing to do. No interesting girls, just young affected little things only interested in sex, I am in direct manner.

  I think I shall go hear the professor's inaugural speech at the R.I. I shall visit the 5 [?] I guess for the weekend.

  I enclose a couple of reprints from The Tatler.

  Dear Professor Pauling,

  I was very interested in your ingeneous cable model of the structure of proteins which appear in Nature. Would you kindly send me two reprints of this paper and reprints of further work on this subject?

  Since there will no doubt be many attempts to verify your model experimentally, I think it is very important that the anticipated inter- ferences be calculated exactly. Dr. D. P. Riley and myself have calcu- lated the equatorial intensities for an aggregate of seven rods (your AB₆ model) in Acta Crystallographica 5 272 (1952) which we have applied to our scattering data for desoxyribose nucleic acid (Biochim. Biophys. Acta 7 526 (1951)). Judging from your earlier paper with Corey, I imagine you calculated the form factor for equatorial spacing ( 1 + 6J₀(X)) by treating the A₆ ring of rods as a shell about the central B rod. However, our detailed analysis of the problem gives for the normalized intensity

  1/49 [7 + 24 J₀(x) + 6J₀ (2x) + 12 J₀( √3x) (1)

  This quantity in turn should be multiplied by the normalized intensity for a solid rod (a fair approximation to your helix) namely by

  [2J₁ (x) / k^R]² (2)

  If the rods are in contact x = (4Л/λ)ρ sinθ .

  If the rods are not in contact (lateral swelling as seems to be the case for collagen, for example) then x in expression (1) above becomes

  (4Л/λ)γ

  ρ sinθ where γ is the "degree of swelling" while x remains unchanged in expression (2) if, as is usually the case, the interatomic distances in the rod remain unchanged on swelling.

  Prof. Pauling January 26, 1953

  For your AB₆ model where the rods are in contact (Y= i.o) we obtain maxima at x=(0), 3.8, and 6.0 (for infinite two-dimensional array there should be a sharp maximum at x=7.2). Taking your rod as 10 A₀ then there should be maxima in intensity along the equator at sinθ / γ = (0), 0.030, 0.048 reciprocal Angstroms corresponding to Bragg spacings (first order) of 16.5 and 10.4 Angstroms. For comparison, an infinite lattice of hexagonally close-packed rods of diameter 10 Å gives a spacing at 8.8 Angstroms.

  You suggest in your paper that there may be overlapping in the X-ray diffraction diagrams of α-keratin at low angles. I am planning to do small angle experiments with keratin to look for fine structure along the equator. I think such work is important to understand the gross structure of proteins of the kind you discuss in your paper. It would be nice if your model of the seven strand cable is correct. Riley and I postulated a nearly similar arrangement for deoxyribose nucleic acid. It is conceivable that the protein cables could fit alongside of or be intermingled with the nucleic acid cables to form nucleoproteins - but I guess I'm off in the realm of fantasy.

  Sincerely and with best personal [sic] regards to you and Professor Corey

  Polytechnic Institute of Brooklyn

  Brooklyn 2, New York

  Dear Dr. Oster:

  I am glad to have your letter of 26 January, and to know about your interest in our α-karatin structures.

  We shall send you two reprints of the paper when they arrive.

  First, as to the form factor of the 7-strand cable, I must say that Crick has written me that he has evaluated the form factor for a compound helix exactly. His expression is without doubt similar to the Cochran, Crick, and Vend expression for a simple helix. I have been interested, however, in approximate expressions that involve less work in calculation.

  I think that the expression that you give for the intensity doesn't apply to our 7-strand cable. Unless I have misunderstood your work, your expression applies to an aggregate of 7 cylindrical molecules in parallel orientation, 6 around a central one. The expression that Corey and I used is an approximate expression for a different ease, that in which the 6 outer helixes are twisted about the central one.

  I have read through your paper on deoxyribonucleic acid - I think that you gave me a reprint, which, however, I lost, so that I had forgotten about your work until reminded by your letter. Unless I have misunderstood this paper too, the structure that you discussed for aggregates of nucleic acid molecules did not involve 6 twisted about a seventh, but rather 6 arranged hexagonally about a seventh, and with axes parallel with that of the seventh.

  Corey and I have a paper in press now, on the structure of nucleic acids. It is to appear in the February issue of the Proceedings of the National Academy of Sciences. The structure is an interesting one, in that it involves three intertwined polynucleotide chains. Each of the polynucleotide chains has 24 residues in 7 turns of its helix. All of the polynucleotide residues are structurally equivalent. There is some evidence in support of the structure. The diameter of the molecule is about 18 A. I am sorry that we did not remember your paper with Riley, in which you suggest a value of 16 A for the diameter of the molecule. We have already read proof on the paper and accordingly cannot introduce the reference now.

  Dr. Oster 29/1/53

  I should be interested to know what sort of work you are carrying on at the present time. You mentioned your plan to do some work on proteins in the future; have you got started on this work, or are you working on nucleic acids, or other substances?

  Sincerely yours,

  Dear Spring:

  I am glad to have your letter of 19 January, and to know that you think well of our new structures for the a— keratin proteins. It seems to Corey and me that there is very little doubt that these structures are correct — although the derivation is not straightforward, there is a lot of evidence in support of them.

  We shall have a short letter in Nature and a paper in the Proceedings of the National Academy of Sciences next month on the structure of the nucleic acids. We think that it is likely that all nucleic acids have the same structure and that it is the one that we have discovered, which in- volves three polynucleotide chains tightly twisted about one another.

  Everything is going along well here. I am looking forward to a brief stay in England in April, probably about 15 April, just after the Solvay Congress in Brussels.

  Lennard-Jones has written several letters to me recently. He seems to be very pleased that he is to be president of your college. He ought to be a good man for the job.

  We all send our best regards to you and your family.
