  Dr. Warren Weaver

  The Rockefeller Foundation

  49 West 49th Street

  New York, New York

  Dear Warren:

  I am writing now to ask your advice about our research program in immunology.

  First let me say that the work in organic chemistry and structural chemistry is going along well. Zechmeister, with two post-doctorate assistants and four graduate students, is making headway on several problems. He has fitted into our department satisfactorily, and there has been no trouble at all of the sort that sometimes accompanies the appointment of a European professor. Carl Niemann is working as hard as ever and as effectively. The molecular structure program is booming along. The crystal structure of alanine, now completed, has turned out to be especially interesting. In this crystal for the first time the positions of hydrogen atoms were verified by the x-ray data. We are now beginning to get good x-ray photographs of large polypeptides, with fifty or one hundred amino acid residues per molecule, and I think that we shall succeed in making complete structure determinations of these. At present we are studying polyglycines, and Dr. Edsall, who is here this year as Guggenheim Fellow, is now preparing some polypeptides containing both glycine and alanine. I am confident that this method of attack, using synthetic polypeptides of known amino acid composition, which might be called artificial proteins, will lead ultimately to the solution of the protein problem.

  For about six months Dr. Dan Campbell, Rockefeller Fellow, and Dr. David Pressman have been working with me on experimental problems in immunology. This work has moved along slowly, because of its nature, but I am pleased with the results obtained. It was fortunate for us that Dr. Campbell was here. Dr. Pressman, an organic chemist trained here, was supported in part from the Rockefeller Foundation and in part from the Noyes Fund of the Institute. All together we have used about $2000 of this year's Rockefeller budget for the work in immunology. The researches completed or under way are the following.

  1. Serological reactions with simple substances containing two or more haptenic groups. We have shown, verifying the work of Landsteiner and van der Scheer, that simple substances containing two or more haptenic groups will give the precipitin reaction with homologous antiserum and produce shock in sensitized guinea pigs. Hooker and Boyd had said that they could not obtain reactions of this type. We have made quantitative studies of the precipitin reaction, determining the amount of antibody nitrogen precipitated by the micro-Kjeldahl method. So far we have positive results for six substances involving arsanilic acid residues attached to resorcinol or phloroglucinol. These results are described in a paper which Campbell, Pressman, and I have published in the Proceedings of the National Academy of Science. The production of a precipitate by simple substances containing two or more groups is, I think, a very strong argument for the framework theory of antibody-antigen precipitates.

  2. The manufacture of antibodies in vitro from normal serum proteins. In my paper I suggested that it should be possible to manufacture antibodies in vitro by denaturing serum proteins and slowly renaturing them in the presence of antigen. Experiments along these lines have been carried out, using three different fractions of beef globulin and the dye methyl blue as antigen. It was found that after denaturation of the protein with alkali or by heat slow renaturation in the presence of the dye produced a protein solution which combined with the dye much more strongly than protein solutions obtained in other ways, such as by rapid renaturation in presence of dye or by various treatments in absence of dye. Similar experiments were started here with bacteria as antigen, and Dr. Campbell plans to continue them in Chicago. Further work is needed to test the specificity of the artificially produced antigens, but the results obtained already are positive.

  3. A quantitative study of sera homologous to antigens containing two different haptenic groups. Landsteiner reported experiments suggesting that no antibody molecules of type A'-B' were present in the serum produced by antigens containing two different groups A and B. This result is incompatible with my theory or any theory involving bivalent or multivalent antibody molecules. With the cooperation of Dr. Landsteiner, we have been carrying out quantitative studies of his sera, and have obtained results which support the conclusion opposite to that reached by him.

  4. The theory that agglutination is the result of the clasping together of cells by bivalent antibody molecules requires that inhibition of agglutination occur on treatment of cells by a sufficiently strong agglutinin solution. Hooker and Boyd have reported failure to produce agglutination in erythrocytes and argue accordingly against the bivalent antibody theory. We are carrying out agglutination experiments using antiarsanilic acid serum as agglutinin and erythrocytes treated with diazotized arsanilic acid as the cells.

  There are many other experiments which we plan to carry out. These include the quantitative study of antibody-antigen composition of precipitates, the determination of equilibrium constants and heats of reactions by physical-chemical methods, especially by the use of various haptens for the study of soluble complexes, the separation of antibodies of different kinds by combination with charged haptens and subsequent electrophoresis, the investigation of the order of the reaction of antibody production by quantitative studies of serum titer for large numbers of rabbits immunized by different amounts of antigen, etc. We are handicapped at present by our inability to determine the amounts of antigens, especially those containing arsenic, in small precipitates with sufficient accuracy. This problem can be solved easily by the use of radioactive arsenic (the isotope As74 made from germanium by deuteron bombardment, with sixteen-day half life), and Edwin McMillan has arranged for this to be made for us in Berkeley when we are in a position to use it effectively.

  I feel enthusiastic about the program of research in immunology, and I would like to carry it on vigorously for some time in the future. In addition to the experiments mentioned above, we have many others under consideration, some of which have been suggested by the immunologists who have written to me since the appearance of my paper. I have, in fact, been carrying on a rather lively correspondence with immunologists of the country, especially with Dr. Boyd in Boston, who is strongly opposed to my theory in so far as it involves bivalent antibodies. I find that immunological work is laborious, and that it moves along slowly unless a suitable number of assistants are available. I am afraid that it would not be possible to take from our present funds enough money to permit the work to be done effectively— we got along this year because of our accidental good fortune in having Dan Campbell here.

  The program which I have in mind would involve the expenditure of about $20,000 per year, with the following budget:

  Research Fellow, Immunology $3000.00

  Research Fellow, Organic Chemistry 2400.00

  Research Fellow, Physical Chemistry 2000.00

  Assistant, Immunology 1500.00

  Assistant, Organic Chemistry 1200.00

  Assistant, Microanalysis and Radioactivity 1400.00

  Apparatus, supplies, animals 7500.00

  Expenses of visiting professor 1000.00

  Total $20,000.00

  As Research Fellow in Immunology I would like to have Dr. Dan Campbell, at present Assistant Professor of Bacteriology and Immunology at the University of Chicago. He is a good technician in the field, an industrious man who works steadily day after day, and a man with interest in chemistry and with an open mind regarding science. I doubt that a better man could be found for this appointment. As Research Fellow in Organic Chemistry I would suggest Dr. David Pressman, who has been carrying on this work this year, and has become deeply interested in immunology. He has been helped in the preparation of organic substances this year by two seniors in chemistry, the two best men in our senior class. Both are American-born Japanese. I think that one might be kept on next year full time as assistant in organic chemistry. The item of $7500.00 for apparatus, supplies, animals would permit us to use the large number of animals required for some of our projected researches, and should permit also the construction of a Tiselius apparatus for the electrophoretic separation of antibody fractions by the suggested method of combination with charged haptens, and for other investigations. I have included the item $1000.00 for expenses of a visiting professor. It seems to me that one of the best ways of assuring that we were making an effective attack on immunological problems would be to bring here each year some authority in the field, for discussion and collaboration. This would be of value also to the people here in biology.

  I would like to be able to plan to carry on this program over a five-year period.

  Would you please tell me whether you think that it would be worth while for an application along these lines to be submitted to the Rockefeller Foundation and if so in what respects the application should deviate from the outline given in this letter. I would like our attack on the problem to be intensive enough to be effective, and the program which I have described above is, I think, just about right.

  With best regards, I am

  Sincerely yours,

  Linus Pauling

  Dear Pauling,

  I had a letter from Jordan, from Nov. 13. He is in the army since the beginning of the war, and his forwarding address is: c/o Pastor Finke, Rolandstrasse 9, Bremen. Probably he is now busy quenching? the fires. He would like to have a reprint of your antibody paper. Apparently he cannot send any of his papers, because there seems to be a prohibition on sending printed matter out of Germany. Apparently he does not feel very much [?] by our note in Science, because he says he does not believe in the resonance idea very much any how

  You showed no reaction to the Frank-Kamenetzky proposal of synthesis by resonance between the reaction product and an intermediate activated state. I was X-mas in Princeton and talked it over with Wigner who saw no serious objection to it. One could probably test it by experiment without to much difficulty.

  April 4 and 5 we are going to have a meeting here of the Southeastern Phycists, nothing to brag about. But we are trying to pep it up by a symposium on molecular structure, with Miss Sponer, Teller, H. H. Nieben, Brockway And Placzek. If an Eastern trip of yours would coincide with this date you would be most enthusiastically welcome to participate.

  With best regards,

  Max

  Professor William C. Boyd

  Department of Biochemistry

  Boston University

  School of Medicine

  80 E. Concord Street

  Boston, Massachusetts

  Dear Professor Boyd:

  I am enclosing a copy of our manuscript on serological reactions with simple substances, and I would be glad to have your comments on it. We have included mention of the substances referred to in your letter, rather than only the substance referred to in the published discussion of your work. Is this satisfactory to you?

  Dr. Pressman has pointed out to me that it is easier to attach azo groups in the 4.5 positions of dihydroxynaphthalene than the 2.7 positions. Have I interpreted your formula correctly as the 2.7 derivative?

  I don't think that there can be misunderstanding about the question of composition of precipitate versus final concentration of reagents when the discussion is detailed enough to be understood. If equilibrium is reached, the composition of the precipitate must be determined by the final composition of the solution. If equilibrium is not reached, this need not be so.

  I do not feel that the lattice theory is necessarily right - that is I am willing to be convinced by the evidence, although I recognize that it is going to be difficult to find a crucial experiment. It seems to me that the available information tends to support the theory rather than to discredit it. For example, I have felt on reading your papers on agglutination that you usually observed separate agglutination of different cells, and observed clumping together only when conditions were just right. This would be expected from the framework theory. How do you explain the formation of separate clumps under various conditions?

  Sincerely yours,

  [Linus Pauling]

  January 23, 1941

  Dr. A. M. Pappenheimer, Jr.

  Department of Bacteriology

  University of Pennsylvania

  Philadelphia, Pennsylvania

  Dear Dr. Pappenheimer:

  I am very sorry to have been so dilatory about replying to your letter. It was a surprise to me to see that two months had gone by since it reached me—the period has been so busy that I have not noticed how long I was delaying. I was very much interested to read your reprints and your manuscript with Dr. Petermann. I am returning the manuscript under separate cover.

  Some of the assumptions in my paper on the structure of antibodies were made for the sake of simplicity. Thus I can not contend that antibodies are necessarily elongated with their active groups at the extreme ends. The evidence which you have obtained shows that this assumption is not always right. Also if the antibodies aggregate the effective valence may be increased, as you suggest. It is not indeed required that the valence of the primary antibody molecule be restricted to 2, but it seems likely to me that most antibodies have the valence 2 because the process of antibody manufacture becomes more complex as the valence increases.

  My theory does not require that the active part of an antibody be less stable than other parts. It does, I think, require that the stability of antibodies analogous to different antigens be in general different.

  The situation regarding antigen activity in relation to strength of groups is not at all clear. I am not sure that the argument which I presented is sound, and nearly every immunologist with whom I have talked has found fault with my conclusion.

  It would be very interesting indeed to know through experiment whether your enzyme treated antitoxin has or has not a higher proline content than the original untreated antitoxin.

  Drs. Dan Campbell and David Pressman and I have been carrying on some experiments during the last few months. We have obtained precipitates with various simple substances containing two or more atoxyl groups and antitoxyl serum, verifying Landsteiner and van der Scheer's results, and we have got evidence that our dye solutions are not colloidal by observing their dialysis through cellophane.

  I hope that I shall be able to talk with you some time. I shall try to visit the University of Pennsylvania on some eastern trip, and I hope that whenever the opportunity presents itself you will make a visit to our Laboratories.

  Sincerely yours,

  Linus Pauling

  Dear Dr Boyd:

  I am very glad to have your comments on our paper. We are changing the wording in just the way that you recommend. It was, of course, wrong for me to write that you failed to verify Landsteiner's observations. Dr. Landsteiner has also written to me that this sentence is incorrect.

  I am having Dr. Pressman send some samples of our precipitable haptens to you.

  I am afraid that, because of ionization, it would be difficult to obtain freezing point or boiling point evidence regarding the molecular state of our dyes. We have, however, shown that most of the dyes with which we worked pass easily through a cellophane membrane, and that the precipitin reaction can be obtained with material which has just passed through the membrane. The pores in the membrane are perhaps about 30 Å in diameter. It is, of course, possible that the dye polymerizes, and exists in equilibrium with the unpolymerized molecules, which again polymerize after passing through the membrane. Nevertheless the ease of dialysis of the dye suggests that they are not largely colloidal.

  I was not suggesting in my letter that you did not publish your observations but rather that your published observations might be interpreted as evidence for the framework theory of agglutination. The first and third paragraphs on page 349 of your 1937 paper on mixed agglutination say that under some conditions separate agglutination of the cells of different types occur and that heterogeneous clumps were obtained only under definite conditions. If the second phase of flocculation were not specific, we might well expect heterogeneous clumps under all conditions, and interpret your observations as evidence against this postulate.

  Sincerely yours,

  [Linus Pauling]

  Dearest little wife:

  I had forgotten how lonesome it is possible to feel in one minute- I think that the lonesomest time of the whole trip is the first minute of parting, when I realize that the whole next week is to be away from you- although perhaps the last day on the way home is worse. I hope that this trip will go by fast.

  I was sorry to see that Crelly was frightened by the train. I had forgotten that he had not seen many.

  As we left the station I looked up at our beautiful foothill slope and tried to find our house, where we all live so happily together, and I thought about you- what a beautiful and good girl you are, how much I love you, how happy I am to have you for my little wife, what fine children you have borne, how wisely you are rearing them- and I promised myself that I would tell you these things when I see you again. I like to think about falling in love with you, and about all the years of being in love with you that have gone by.

  This afternoon I have read- applications, Spurr's article, the Saturday Evening Post- sitting in my Pullman seat. Only now have I come back to the observation car to write to you, at the little writing table. I notice now (as on the last trip) that I have begun to feel carsick- I think that it may be due to my bending over the table while writing.

  The mountains and desert have been beautiful- the bog rocks on the way up to Cajon Pass, the snow-covered San Bernardinos, the Joshua trees near Victorville, the Calicos. Now it is dark.

  Give my love to the children, dear little wife.

  Much love from you

  Linus

  Dearest Paddy:

  I have just finished my work - supper - dishes - and a great lot of oat meal cookies. If you were here I might let you have one. I’ve decided to send some to James. He likes them so well and it is a shame that he should have them only once a year. Little Crellie and I watched your train sail on out of sight then we drove home via New Oak [?] Avenue. I purchased a flat of verbena, too, and they are already in the ground. Linus is at a He Y [?] meeting. He said he didn’t want to go but that he had to go. I said “Nonsense.” Also that I wouldn’t come and get him since I’m tired. I think I won’t go. He wanted to stay overnight tomorrow night too, with the little [?] girl, I mean, but I said he couldn’t that I would get him at eleven o’clock. He is a scheme all right and clever, too.

  How are you? Dr Edsall called and invited me to their house tomorrow evening to meet some English people whom they met in Berkeley. I don’t want to go very much but will go first for a little while to the folk dancing and then for a short while to the Edsalls’. Isn’t it odd that he called? This afternoon I called on the Tylers with Crellie and Linda while we waited for Peter. She was happy to see us and they have a charming little house and garden. It is too bad she hasn’t some of Lena Weinbaums [sic] excess artistic talent. Say do you realize you didn’t give me your address in New York? How can I write to you? Such a fellow! How is the little Paddy? You are a big joke. A man called to ask if our property here for sale. I said “No.”

  I suppose you think you are pretty smart don’t you. Guggenheim Advisory Board. Fui! [sic] They ought to know who the Paddy Advisory Board is. I’m going to read the paper in bed and I won’t be bothered by any pestiferous Paddy either.

  Love to you, Member of the Selection Board of the John Simon Guggenheim Memorial Foundation — to say nothing about the Advisory Board. Ava Helen Pauling
