  Dear Tom:

  I was very glad to see your two letters when I got back from the East on Friday.

  A week ago Friday I had a good visit with Dr. Robert Loeb, whom I had not met before. He talked to me a long time about the blood substitute situation. He told me that so much human plasma is being collected that the C.M.R. now feels that the blood substitute problem is no longer so urgent as it was a year ago. Moreover, the unsatisfactory outcome of the bovine albumin project has discouraged the blood substitute group somewhat. Nevertheless, his committee will, I think, support some blood substitute work, such as that which we are carrying on.

  I am glad to learn that you are now getting more promising results with pectin than before.

  Why do you not write to Loeb and submit to him your suggestion regarding the possible use of human globin? It seems to me that this idea might well be worth some preliminary work. I suppose that there is some danger that the process of removal of the hemes would alter the globin in such a way as to produce toxic reactions, but this could be answered only be experiment.

  We are going to start out now to prepare a large amount of our polyoxy gelatin, and to give it as complete characterization by physical-chemical methods as possible, before submitting it to physiologists. I hope that we shall have some ready for you before many months have gone by.

  Dr. Koepfli told me that you had composed a fine letter to the C.M.R., advocating that more technical aides be hired and that other similar measures be adopted to improve the efficiency of the Committee. He said that he had obtained several signatures for the letter down here. I am glad that you have gone ahead with this work, along these lines. Robert Loeb told me that he had difficulty in keeping up with his C.M.R. duties, because he does not have any technical assistance. I think that he should have a technical aide.

  We were all happy to have you and Mrs. Addis here, and I hope to see you again before long.

  Sincerely yours,

  Linus Pauling

  May 7, 1943.

  Dear Dr. Pauling:

  Your letter of April 1st to Professor Millikan and the enclosed reports and request have been forwarded to The Rockefeller Foundation by Dr. Millikan. These documents have had serious study by the officers and we have also consulted a number of the leading workers in the field regarding the project.

  We have recognized that the stakes were very high in this venture and therefore were willing to recommend to our Trustees the very substantial support of $31,000 which you have had this past year. This support was given with the hope that the critical central point at issue could be cleared up before the termination of the grant. As we understand it, this critical point is whether antibodies can be manufactured in vitro or not. From the conferences we have had during the past month with our advisers in this field it seems reasonably clear that the question in which we are primarily or even solely concerned -- the production of artificial antibodies -- is not unambiguously settled. It was also brought to our attention that work on the central problem involved should require only a relatively modest financial setup.

  The officers are willing, after deliberation, to recommend for another year such a sum of money as may be necessary to secure as definite and clear a decision as may be possible on this central point. We would do this with the hope that another year of work might result in the publication of experimental evidence in such clear and detailed form that experts could evaluate the results precisely, and that the technical procedures in their smallest details should be so described that the experiments could be repeated exactly elsewhere, should anyone desire to do so.

  It does not seem to us that we should consider going in for the support of immunology on a broad front at the present time. In fact, our advice is that if the manufacture of antibodies in vitro were unequivocally demonstrated, this would open up such vistas for research that support from many sources would be available and we could withdraw and use our funds for opening other new fields. This would be directly in line with best Foundation principle -- namely, to take the gamble in the initial stages of an unusually promising situation, developing it to the point where it commands other support. We would like to have your best estimate as to what funds -- in addition to the $11,000 already available -- you would need for a strong attack upon the problem of the production of artificial antibodies.

  In the consideration of this financial question there is one aspect of the budget submitted which gives us considerable concern. We do not, as a matter of policy, pay the salaries of permanent members of the staff of an institution. At least in those few exceptions where we have done so for a brief period it has always been with the understanding that the University take over the salary at a specified time. I am of course speaking of the status of Dr. Campbell, who appears in the budget as “Assistant Professor”, but whose salary is requested from The Rockefeller Foundation. Our grants usually contribute salaries of research assistants on a year-to-year basis. In the case of an Assistant Professor or other regular staff member, we prefer not to assume the implied responsibility when such a person is paid from our research aid grant. This must necessarily be true since the Foundation rarely enters into long-term commitments, and there is never any obligation, moral or legal, on the part of the Foundation to renew grants at the end of the one, or two, or three-year period for which they are given.

  I am writing to Professor Sturtevant regarding the biological side of the request from California Institute of Technology. Our last meeting until fall will be held in June, and all information regarding grants for that meeting should be in my hands at the latest, June 1st. the next meeting will not be until sometime in October.

  Sincerely yours,

  Frank Blair Hanson.

  Dear Dr. Stewart:

  We have received the enclosed inquiry concerning the oxygen meter. If your office will give us permission to discuss it with Major Ribal or other responsible representative of the Fourth Antiaircraft Command we shall do so.

  Do you see any objection to modifying the classification of this instrument in whatever way may be necessary to give us continuing permission to discuss the meter with any responsible representative of the armed services to whom it may be of interest? If there are no objections to this, such permission would probably facilitate the application of our instrument to war problems.

  If this latter question requires some time to decide, will you please send us your decision with regard to Major Ribal first?

  Very truly yours,

  Linus Pauling

  Dr. Frank Blair Hanson

  The Rockefeller Foundation

  49 West 49^th Street

  New York, New York

  Dear Dr. Hanson:

  Your letter of May 7, in which you ask that I revise our request to the Rockefeller Foundation for additional support for our work in immune-chemistry during the coming year, has raised several questions which cause me concern. I am writing this informal letter to you in order that I may get additional information, to clarify my thoughts. The requested revision is given in the accompanying letter.

  I. You have said that you would like to have our best estimates as to what funds – in addition to the $11,000 already available – we would need for a strong attack upon the problem of the production of artificial antibodies, and earlier in your letter you mentioned that the question in which you are primarily or even solely concerned is the production of artificial antibodies. Of our work in immunochemistry as a whole, I have thought and now think that the work on artificial antibodies represents only a minor part. My 1940 paper on “The Structure and Process of Formation of Antibodies”, which led to our experimental work in immunochemistry, mentioned the possibility of production of artificial antibodies in three sentences, and in our application to The Rockefeller Foundation in 1941 for a grant of $11,000 a year for three years this was given only minor emphasis. Other experiments which we have carried on and are carrying on are, I believe, of much greater scientific interest, because of their easier theoretical interpretation. The manufacture of artificial antibodies is, of course, interesting in itself and especially so because of the possibility of practical application.

  I accordingly ask now if you do not think that we are justified in considering that the grant of $11,000 a year does not relate primarily or solely to the production of artificial antibodies.

  II. Let me recall the circumstances attending the additional grant of $20,000 for work on artificial antibodies during the present year. Because of the possibility that our artificial antibodies might be of practical value, arrangements were being made a year ago with the Committee on Medical Research whereby a contract for $20,000 would be given the California Institute of Technology for the study of artificial antibodies, and especially their ability to protect animals against disease, during the year 1942-1943. When I learned that The Rockefeller Foundation might prefer to support this extended project, I withdrew the application to the Committee on Medical Research and submitted it instead to The Rockefeller Foundation. The work on this project during the past eight months has proceeded reasonably well. We have been hampered by difficulties in getting equipment, due to wartime restrictions. We have been having especial difficulties with the supply of animals; our own facilities have not yet been built up to a satisfactory state, and a few months ago the animal supply houses available to became unable to fill our orders. The present state of our results is that the artificial antibodies which we make, and which show some of the properties of animal antibodies, cannot yet be said to have or not to have the power of protecting animals against disease to a sufficient extent to give them possible practical value.

  The mouse protection tests which have been made show that none of the preparations of artificial antibody made by the various methods tried so far have protective power comparable with natural antibody against Type 1 pneumonia. The preparations of the artificial antibody which give the precipitation reaction with Type 1 polysaccharide show, however, a small but definite protection. We have made a great many experiments, changing the numerous variables involved, in the effort to increase the protective action until it approaches that of animal antibody. In addition, all the needed facilities have now been obtained to carry out neutralization tests with diphtheria antitoxin, and this work is just being begun.

We have made a great many experiments, changing the numerous variables involved, in the effort to increase the protective action until it approaches that of animal antibody. In addition, all the needed facilities have now been obtained to carry out neutralization tests with diphtheria antitoxin, and this work is just being begun.

  III. I am not sure that I understand the fourth paragraph in your letter, in which you say that if the manufacture of antibodies in vitro were unequivocally demonstrated, this would open up such vistas for research that support from many sources would be available. Influenced in part by your letter of last year, we have not expected that the California Institute would profit from the possible commercial developments of any discoveries made here in this field, and in particular we have not accepted help from commercial firms. The only exception which has been made to this is that we have accepted gifts of small amounts of materials from three different pharmaceutical houses. Also, as mentioned above, we have not accepted financial aid for this work from the Committee on Medical Research, whose interest in it led to its expansion this year. Are we to understand that you now recommend that we consider the possibility of commercial support of our work? I myself do not look upon this idea with favor – I am interested in fundamental scientific studies, of the sort which do not ordinarily attract the support of commercial firms, and I would not like to be influenced in charting my research program by commercial considerations.

  IV. When I recommended to the California Institute that Dr. Dan H. Campbell be appointed Assistant Professor of Immunochemistry, I did not know that The Rockefeller Foundation would object to the change of title from that mentioned in my application, Research Fellow. We fully understand that The Rockefeller Foundation has assumed no responsibility whatever for our work in immunochemistry beyond the termination of the period of the grant. If you feel that it is not proper for Professor Campbell’s salary to be paid from The Rockefeller grant, please let me know at once, and I shall begin at once to arrange for another source of funds to cover his salary.

  V. Let me say that I have thought of our immunochemical program as being much more than merely an effort to manufacture artificial antibodies, more even than a fundamental research program in immunochemistry – I consider it to be an effort to introduce a new point of view into the research in immunology. A few months ago we had at the California Institute an enthusiastic group of nearly twenty young men devoting all or part of their time to immunological research, carrying on experiments which in part embody new ideas (the group is somewhat smaller now). I have been pleasantly surprised to see how great the interest of our graduate students in chemistry is in this new field in which we have begun work; the majority of the men majoring in organic chemistry have been choosing immunochemistry as their minor subject. I think that we may expect that some valuable contributions to science will result from the inculcation of an interest in immunology in these young men who are well trained in chemistry.

  VI. While recognizing that The Rockefeller Foundation has no obligation to continue its support of our work after 1944, I have thought it possible that our contributions to the field of immunochemistry during the period of the present grant might be considered of sufficient importance, and the promise of more results sufficiently apparent, that The Rockefeller Foundation would be interested in enabling us to continue the work beyond 1944. Our decision as to whether or not to make application to your Foundation need not be made for another year, and I mention the matter now only because of its relation to the suggestion that The Foundation might prefer to withdraw from the project if it could command other support.

  Sincerely yours,

  Linus Pauling

  Ser. No. 405,991

  Filed: Aug. 8, 1941

  For Process of Producing Antibodies

  Mailed May 11, 1943

  Responsive to amendment filed July 4, 1942

  Further references:

  Articles cited as footnotes 2, 3, 4, 5, 7 to 12 of Jour. American Medical Association of August 15, 1942, pages 1376 and 1377 on Artificial Antibodies - copy of J. A. H. A. in Pat. Off. Lib. These articles are probably available at the Surg. Gen. Lib.

  The claims are again rejected for lack of utility as no evidence has been presented to show that the anti-bodies alleged to be produced by the method claimed have any utility at all. Applicant points out that antibodies for methyl blue, the only specific alleged antigen, has no known therapeutic use but such antibodies find utility in methods of laboratory analysis. There is no showing of how such antibodies can be used for analysis purposes. As the disclosure stands, it would be necessary to carry out further experimentation in order to determine if antibodies are obtained by the method and then to ascertain how to use them for some useful purpose. The claims are accordingly rejected as biased upon a method lacking in utility. Any evidence relied upon to prove utility should be presented and made a part of the record.

  The claims are also rejected as being alternative in the use of an improper "Markush" formula. Applicant is using the expression "a member of the group including antigens and haptens". The only expression permitted under the "Markush" formula is a "material selected from the group consisting of A, B, C, and D". See Ex parte Markush 1925 CD 126 and Ex parte Dotter 12 U.S.P.Q. 382. Thus this rejection nay be overcome by using "consisting of" in place of - including - in the claims and using the singular instead of plural in describing the members of the group.

  The claims are rejected as being too broad, functional and indefinite in reciting all proteins, globulins, haptens, denaturing agents, etc. On the basis of the limited disclosure made, there are insufficient examples to warrant claims of this scope. The claims are functional and indefinite as they define the process by the results desired rather than by those steps which yield these results. For example the recitation of "denaturing a protein" without reciting those steps which accomplish this purpose renders the claims functional See Jenson v Franklin 74 F (2d) 501, In re Stack 479 0G 997 and In re Fischer 485 0G 761. The claims are too broad in the denaturing of the protein step since if too much heat, for example, is employed on the protein to destroy the same, the removal of the heat would not cause the formation of antibodies.

  Claims 1 and 5 are rejected as alternative in the use of the word - or -.

  The claims are rejected for lack of invention over the work of the prior investigators set forth in the J. A. M. A. of Aug. 15, 1942 which in the footnotes give the citation of the original articles, all of the pertinent ones of which antedate this application and therefore constitute references against this case. The bottom of page 1376 and top of page 1377 points out that applicant's method is "A process similar to that originally adopted by the Soviet immuno-chemists". Footnotes 2, 3, 4, 5 and 7 are citations of these articles of these prior investigators. The claims are therefore considered as not being patentable over these old and similar methods previously used for the purpose in view.

  All the claims are rejected.

  Dear Professor Lamb:

  In the manuscript which accompanies this letter, Professor Zechmeister and I and our collaborators have indicated Roman type for the words cis and trans when not used as prefixes in chemical names. It seems to me that this simplification is a desirable one, since these words can, I think, now be taken into the English language. I am writing now to ask if you are not willing to permit us this usage; and further to inquire as to whether it may not, in your opinion, be well to consider the possibility of using these prefixes in chemical names without italicizing them.

  Cordially yours,

  Linus Pauling

  May 24, 1943.

  Dear Dr. Pauling:

  This will acknowledge your letters of May 17, regarding the status of the immune-chemical project. The officers will be happy recommend the sum of $8,000 of new funds for continuing the work on the production of artificial antibodies during the year beginning July 1, 1943.

  I am sorry if any misunderstanding has arisen regarding the importance you attach to the various parts of your program. None of us in this office can claim any competence in the field of immunology, but the fact remains that the best advice we can get from a number of leading workers in this field focused primary attention upon the importance of determining as clearly as possible and as quickly as possible whether artificial antibodies can be produced in the laboratory. If this can be done unequivocally, our advisers foresee advances in infectious disease therapy of the greatest importance. From your letter of March 25, 1942, requesting an additional grant of $20,000 for the present year, we gained the impression that you also were of the opinion that the most interesting results you had obtained were those dealing with the manufacture of antibodies in vitro, and that it was of great moment that this line of investigation be pushed rapidly. Since the impression we gained from your letter of a year ago coincided exactly with that of our advisers, we recommended, the $20,000 with very considerable enthusiasm. In view of this bit of back-ground, you can understand our somewhat mild, surprise to learn, from, your most recent letter, that you have thought, and now think, that the work on artificial antibodies represents only a minor part of your program. The misunderstanding on our part may be further explained by the fact that we were requested to furnish $20,000 for the work on antibodies in vitro and only $11,000 a year for the broader aspects of the program. This seemed to make the artificial antibody work your major interest and the other aspects of the project your minor interest.

  The fourth paragraph of my letter, upon which you comment, was undoubtedly poorly phrased and undoubtedly misleading. It was farthest from my intention to recommend that you consider the possibility of commer-cial support for your work. I merely meant to point out that in the opinion of our advisers, once the fact that antibodies could be made in a test-tube had been established, there would be, as in the case of all major advances in science, a very considerable number of persons who would at once take up the new technique and carry on research along this line also, and that for these several centers there would be many different sources of support.

  Your statement regarding Dr. Dan H. Campbell and the responsibility of the California Institute of Technology for his future is entirely satisfactory to the Foundation, and I see no reason why you should not continue his salary from Foundation funds until the expiration of the present grants, at which time, of course, we shall be happy to consider with you the future of your most interesting work in immune-chemistry.

  I wrote to Dr. Sturtevant about his part of the request at the same time I wrote to you. I have not heard from him, and since all material must be in our hands by June 1st, at the latest, I wonder if it would be asking too much of you to check up with Dr. Sturtevant to see if he is working on the matter and if I may hear from him in the near future?

  Sincerely yours,

  Frank Blair Hanson.

  Dear Mom,

  I was extremely glad to hear from you, but I am very sorry to hear that you were unwell again. I hope that your illness clears up permanently. I am ashamed of my lack of letter writing; it is inexcusable.

  I have been to see Porgy and Bess and The Gypsy Baron by Johanna Strauss. Porgy was wonderful especially the male singers, including Tod Duncan. Irra Petina was in the Gypsy Baron, and was quite wonderful; the completely eclipsed the other members of the cast.

  I went through hell week, and had extremely sore and black and blue buttocks for awhile. I didn't have fifty four dollars on hand, so I couldn't go through with formal intention.

  Tell Flintridge that it is very doubtful that I will be down for graduation. It is possible, but improbable. I should like graduating very much, but it give me too little time for working, I'm afraid.

  I shall be happy to see my family again. All the kids much have grown tremendously.

  Love,

  Linus

  New York, New York

  Dear Dr. Hanson:

  I thank you for your letter of May 24, which answers the questions which had teen troubling me.

  Professor Sturtevant has told me that his answer to your earlier letter was mailed today.

  I think that the opinion which I expressed in my letter of May 17 regarding the importance of artificial antibodies in comparison with the other investigations in the field of immunochemistry which we are making did not tell the whole story. From the point of view of pure science, the other investigations are, I think, of greater interest and importance than the manufacture of artificial antibodies, because they lend themselves to more definite and straightforward theoretical interpretation. On the other hand, the manufacture of artificial antibodies offers some promise of being of practical value in, the prevention and control of disease, and when I think of this I become enthusiastic about artificial antibodies, and am tempted to rank this part of our work as the most important. As mentioned before, our experiments with artificial antibodies against Type I pneumonia indicate a small but definite protective power; I am disappointed that striking protection has not been achieved.

  I thank you for recommending that the sum of $8,000.00 be provided for continuing our work on the production of artificial antibodies during the coming year. I am confident that during the coming months we shall obtain enough information to give a reasonably definite answer to the question of whether or not artificial antibodies will be of practical aid in the protection against and treatment of disease.

  Sincerely yours,

  Linus Pauling
