  The Rockefeller Institute for Medical Research

  66th Street and York Avenue

  New York, New York

  Dear Dr. Landsteiner:

  I have received my manuscript from you, and the suggestions which you make. I shall revise it in accordance with these suggestions, and then complete the manuscript by the discussion of specific examples.

  I would, however, like to have you tell me whether or not you are generally satisfied with the way the manuscript is written— that is, have I started out in a way that seems satisfactory to you. It may be that you would prefer to have me write a much more detailed and advanced treatment than the one which I have prepared, and if so I would do this. Please let me know whether or not you are satisfied in general.

  I agree with you that ionized groups are in part responsible for antigen-antibody union. I would, I think, classify these with weak interatomic forces in a medium such as water, which because of its high dielectric constant reduces the strength of attraction between ionized groups.

  I was in New York for a day last week, attending a meeting of the National Defense Research Committee. I stayed overnight with the Mirskys and I wanted to see you, but unfortunately was not able to find time.

  With best regards, I am

  Sincerely yours,

  Linus Pauling

  P.S. I would be interested to know what you think of our experiment on the manufacture of antibodies. A young man from the Lederle Laboratories, Dr. Harrison Davies, who spent two years here as National Research Fellow in Medicine, was here a couple of weeks ago, carrying out some tests. He made a very satisfactory antiserum against one of the resorcinol dyes, and seems to have convinced the Lederle group that the method is all right.

  Dear Wendell:

  We have sent separately to you a portion of bovine gamma globulin, which we have been using in our manufacture of antibodies. We have usually used a solution one per cent or two per cent in globulin, dissolved in 0.9% sodium chloride. As you know, we have found that procedure of heating at 57° for a number of days in the presence of antigen pretty satisfactory. Adding alkali to pH 11 and then slowly returning to neutrality by dialysis against butter also works, but of course cannot be used with your virus. For separating the antibody from antigen precipitation by one-third saturated ammonium sulfate seems to be very satisfactory.

  I hope that you will carry out some experiments on the preparation of antisera against viruses, and let me know how they come out.

  Sincerely yours,

  Linus Pauling

  California Institute Research Foundation

  1201 E. California St.

  Pasadena, Calif.

  Gentlemen:

  On April 9, 1942, at a meeting of the Trustees of your Foundation, I presented orally a statement regarding the invention of the oxygen meter.

  I now suggest that an agreement be reached between the Foundation and Linus Pauling, J.H. Sturdivant, and Reuben Wood, as follows:

  1. The Inventors (LP, JHS, and RW) assign to the Foundation all patents on inventions relating to the oxygen meter that have been made or shall be made by them before January 1, 1944, unless the Foundation rejects them.

  2. In consideration of these assignments and of the effort of the several Inventors in reducing the inventions to practice, the Foundation agrees to make to the Inventors payments totalling 25% of the net receipts from the inventions, according to the following schedule agreed on by the inventors among themselves:

  Linus Pauling 20

  J.H. Sturdivant 5

  Reuben Wood 5

  3. The net receipts from the inventions are to be the sums remaining from the gross receipts after the Foundation has been reimbursed for patent expenses, expenses of litigation, and other expenses incurred by the Foundation in connection with the oxygen-meter patents, as reasonably estimated by the Foundation.

  4. Neither the Inventors nor the Foundation shall receive any royalty under these patents on devices sold to agencies of the United States Government.

  5. Neither the Inventors nor the Foundation shall contest the validity of or title to any of these patents.

  6. This agreement may be revised at any time by consent of both the Inventors and the Foundation.

  Dr. A.N. Richards, Chairman

  Committee on Medical Research

  2102 Constitution Avenue

  Washington D.C.

  Dear Dr. Richards:

  I am pleased that your Committee is favorably disposed toward the transfusion project which I have proposed. I think that your suggestion that th ework be begun on a less imposing scale is a very good one. I suggest that the original proposal be essentially cut in half, according to the following budget.

  Technical Assistants (probably one

  Ph.D Assistant, one or two

  Junior Assistants) $5000.00

  Animals, Chemicals, Apparatus 2000.00

  Total $7000.00

  With 50% overhead on the salary budget, this amounts to $9,500. I feel that if no really promising results are obtained by an investigation corresponding to this budget, it would not be worth while to continue the work.

  I hope very much that, in case this contract is approved, it will be possible for us to be provided with the various fractions of bovine serum proteins which are being made by Armour and Company and other companies.

  Dr. Baird Hastings suggested to me in New York last week that your Committee might ask us to work on some other problem. We would be very glad to do anything that you think worth while.

  Sincerely yours,

  Linus Pauling

  Dear Dr. Sherwood:

  Thanks for arranging the extension of $2000.00 on our present contract.

  I shall put through a purchase order with the Bell Laboratories for the job that Dr. Bozorth is doing for us. I do not know yet whether that will come under our present contract or under the contract starting July 1, or perhaps divided.

  The suggestion in your letter of May 13, 1942 that our next contract be a one-year contract involving $4,800 for salaries, $2,400 for overhead, and $2,800 for supplies and travel is quite satisfactory to me. It corresponds closely to the proposal in my letter of April 10, 1942.

  We are now building instruments covering the range 0-40 mm. of oxygen. I think that there would be no great difficulty in building an instrument for Mr. T. H. Chilton to cover the range 0-15 mm. of oxygen in ethylene, with reasonable accuracy, provided that we knew the pressure of ethylene which would ordinarily be present. Change from one atmosphere of ethylene to one half an atmosphere, for example, would cause an error of a millimeter or two in the reading, but if the ethylene pressure were kept roughly constant this trouble would not arise. At present we would have some difficulty in making an instrument giving much accuracy over the range 0-8 mm., but I hope that after Dr. Bozorth has completed his investigation on improvement of the magnetic circuit an instrument of this type could be built. In a month or two I shall have information on this point.

  Yours truly,

  Linus Pauling

  Dr. Edwin J. Cohn

  Harvard Medical School

  Boston, Massachusetts

  Dear Dr. Cohn:

  We have just been granted a contract by the Committee on Medical Research for the investigation of the possibility of treating antigenic protein solutions with chemicals such as bis diazotized benzidine or other bifunctional reagents so as to mask their antigenic groups. This is a pretty long shot, and I am not expecting favorable results from the first trial. Dr. Hastings told me that you had made some experiments along these lines, and I would be very glad indeed to know what they were and what results were obtained.

  We have been helped in our artificial antibody work by having at hand the supply of bovine gamma-globulin which Armour and Company sent us with your permission, and I want to thank you again for making this arrangement for us. it would be very useful if we had for our masking project various fractions of the bovine serum proteins. Dr. Richards has suggested that I ask you if you could supply us with these fractions. I think that the fractions on which we might work most effectively would be those bordering on your non-antigenic albumin fraction, about which I have obtained only brief word-of-mouth reports. Thus if you had available in large quantity a fraction which was antigenic but only slightly so, we might be able by relatively simple chemical treatments to remove the antigenicity. I would be very glad indeed to have your opinion about this matter and about the project as a whole, and also I would be very grateful to you if you could provide us with fractions of bovine serum proteins.

  The personnel for this project has not yet been settled. It is probable that Dr. J.B. Koepfli, Dr. Carl Niemann, and Dr. Dan H. Campbell will spend smaller or greater parts of their activities on this work. We propose as a first step in the investigation to determine the antigenicities of proteins, using rabbits as test animals, and then to see if there is any loss in antigenicity on chemical treatment.

  I have also another request to make of you. As I mentioned in my letter last summer, we would like to try to human gamma-globulin as the raw material for artificial antibody manufacture. Some time ago Dr. Koepfli received a letter from Mansfield Clark of the National Research Council asking if we had need for human serum fractions other than albumin. At my request he answered that we would like to have some human gamma-globulin, but although he has been busy writing letters about the matter no results have been obtained.

  [2]

  I think that perhaps your Laboratory would have been the primary source of the material, and that I should have written to you again about it. So now I ask if it would be possible for us to obtain a reasonable amount, of the order of magnitude of 50 grams, of human gamma-globulin or some similar fraction for use in this other investigation, dealing with the manufacture of antibodies in the laboratory.

  It has been a long time now since I have come to Boston, and I have no plans to make such a visit soon, but I hope that we may get together one of these days. Please give my respects to Dr. Edsall.

  Sincerely yours,

  Linus Pauling

  Dear George:

  I am sending you this letter for use in connection with the clearance of Dr. James Holmes Sturdivant for national defense work.

  I have known Dr. Sturdivant for fifteen years. During the period 1927-1930 he carried on graduate work in chemistry at the California Institute of Technology under my direction, and since 1930 he has worked continuously as a Research Fellow, Senior Fellow in Research, and Assistant Professor of Chemistry. Throughout this time I have been in very close contact with him. I have complete confidence in his honesty, integrity, and loyalty to the United States of America. I rate him as the most reliable and trustworthy man that I know.

  Sincerely yours,

  Linus Pauling

  Washington, D. C.

  Dear Professor Adams:

  I would be glad to have your opinion as to whether or not I should be scheduled to receive a salary from the OSRD during the summer. So far as the California Institute of Technology is concerned this is permissible, since the salary payments here are for work during the term of the academic year.

  The amount of time which I am devoting to war researches has been steadily increasing, and it seems likely that I shall put in all of my time during the summer on war work. At present I am serving as Official Investigator under two contracts from Division B, and I have just been granted a contract for work on transfusion by the Committee on Medical Research. In addition I have been supervising some work under a work order from Division A. Now that I have given up my plans for completing the preparation for publication of my textbook in freshman chemistry during the summer, the only work which I propose to carry on which is not under the OSRD will be the Rockefeller research program on the artificial production of antibodies, which has the sponsorship, if not the financial support, of the Committee on Medical Research.

  It is probable that the construction in quantity of the oxygen instrument will soon be turned over to the National Technical Laboratories, so that I shall not have to devote time to this. On the other hand, Kistiakowsky has invited me to spend a part of the summer working as Consultant to the group at Bruceton, and I am looking forward to being there for a month or more. My wife is planning to go to Bruceton with me, since I have trouble with my diet when I am away from home for more than a few days.

  I want to thank you for inviting me to the meeting in New York. I was very pleased to be present and to learn of the work that is being done by the other sections of Division B.

  Cordially yours,

  Linus Pauling

  Dear Dr. Hanson:

  I am very pleased indeed that the officers of the Rockefeller Foundation have found it possible to act favorably on my application for an additional appropriation during the coming year for support of our researches in the field of immunology.

  I am now working on the problem of increasing our staff of research fellows and assistants. Dr. Dan Campbell, who in March returned to the University of Chicago to give lectures in immunology, will be back in Pasadena on July 1, with the title of Assistant Professor of Immunochemistry. Dr. David Pressman will continue as the principal organic chemist of the group, and I hope that one more senior investigator can be appointed. We are having no difficulty in finding suitable younger people as assistants.

  You know that the Committee on Medical Research has expressed its interest in the work. With this sponsorship, we shall, I think, not find it necessary during the year to curtail our program of immunochemical research because of the war situation. Although the chances that our work on artificial antibodies will lead to results of practical value in the immediate future are not great, there does exist some possibility that the researches will have practical application.

  The Committee on Medical Research has given us a small contract for a program of research on the chemical treatment of protein solutions in the attempt to find a substitute for human serum for transfusion. This work is of course somewhat related to our programs of research in immunochemistry, but it represents an off-shoot which we would not have thought of following except for the demand for serum substitutes caused by the war. The personnel under this contract will be entirely separate from that of the immunochemistry program, except that it is expected that Dr. Campbell and Dr. Pressman will be called on to give advice occasionally in connection with the transfusion work.

  Later in the summer I shall make you a report on the progress of the immunochemistry program. There are so many interesting things to be done that we are having trouble in carrying separate researches to completion.

  Sincerely yours,

  Linus Pauling

  1 West 68 Street

  New York, New York

  Dear Alfred:

  I have just received notice from the Rockefeller foundation that they have made us an additional grant of $20,000 for research in immunochemistry during the coming year, and so I can write to you confirming the offer of an appointment for you here. The position would carry the title Research Associate and the salary $4,000 for the year. The duties of the post would be definite: To carry on research in immunochemistry as part of our program of immunochemical research supported by the Rockefeller Grant. I know that this is not ideal for you, and that you might well prefer to stay in your present position for a couple of years, and continue with your own interesting work, with the expectation that a more satisfactory appointment would be arranged for you later. I can express my feelings about the matter by discussing the three points which you raise in your letter.

  1. I agree with you that it would be fine if you could continue to work on your own research program, without interruption. But the only funds available for your appointment are those granted specifically for our definitely outlined program of research in immunochemistry, and if you were to accept the appointment it would be necessary for you to work in this field. I would be very glad indeed to have you here so that I might discuss with you not only the work which you yourself would do, but also the rest of the immunochemistry program. I feel that you would soon become very deeply interested in this work, especially since the part of the work dealing with the artificial manufacture of antibodies is so closely related to your own work on the renaturation of proteins.

  2. It would not, I am afraid, be possible for you to do any regular teaching during the coming year. The number of students has fallen off somewhat, and we have been eliminating some of the advanced courses for the duration of the war. We have even been having trouble in keeping up sufficient interest in seminars. Of course, we might well have a special seminar on immunochemistry or on our protein program in general, and I would expect you to take an important part in this.

  3. As I said to you in New York, I myself would think of your change from New York to Pasadena as permanent, even though the appointment which can be made at present would be for only one year. You know that the Institute is living on a somewhat hand-to-mouth policy, and that there is not available any endowment at present permitting further permanent expansion. But I think that there is very little doubt that our protein research program will be continued, and that your research appointment would continue. I would hope, of course, that in a few years a permanent arrangement for this extension of our field of activity could be made. You know how our development of organic chemistry took place; first we were given a grant for a six-year period, expiring two years from now, but endowment was made available which permits the work to be continued on a slightly restricted scale thereafter. It is true that I shall have in 1944 to meet the problem of seeing that the decrease in our budget for organic chemistry is satisfactorily handled.

  Well, that is the situation. It is by no means ideal, and compared with your present position it suffers from disadvantages so great that I could well understand your decision to stay in New York. On the other hand, I think that the advantages of coming to Pasadena might really be great enough to justify a favorable decision on your part. Although the appointment would technically be for one year, you, as I, should consider it as being indefinite. And I think that you would have a great opportunity, with your extensive background of experience on handling proteins, to accomplish a tremendous amount of work in the laboratory in this newly opened field of artificial manufacture of antibodies. As you said to me in New York, the field is wide open, and an immense amount of work could be done very quickly be a vigorous attack. Do you not think that it might be worth while to give up your present interests in order to jump into this work with me, and perhaps clear up some of the interesting questions connected with it? When, as in this case a new technique becomes available, it is possible for very interesting researches to be carried out quickly and relatively easily. And I am sure that I would benefit a great deal by discussing with you all of the phases of our program

  I think, although I shall not be sure until I make a thorough study of our budget, that we might be able to give an appointment as assistant to you to the young fellow who is now working with you. Our stipends are of course not very large—at present we are paying $1200 a year to the young assistants on this program.

  Since I must make arrangements for the year’s work without delay, I shall look forward to hearing from you soon. I hope that you will find it possible to overlook the disadvantages of this scheme, to concentrate on its advantages, and to accept the appointment.

  I have been so busy since getting back that I have not written to Reba to thank her for her kindness to me in letting me stay with you in New York, and also to thank her for the book which she left for me to read on the way home. Please give my thanks to her, and tell her that I am hoping that you will all be out here during the summer, settling down for your Pasadena career. Dr. Campbell will be here on July 1, returning from Chicago, where he has been lecturing, and will begin, with his assistants, at once to carry out his researches. Dr. Pressman, who has been hard at work for nearly two years with no more than a week’s vacation occasionally, will probably take a vacation of about a month in August. The Rockefeller grant on which your appointment for the first year would be made covers the period July 1, 1942 to June 30, 1943. I hope that it might be possible for you to come rather early in the summer, so that I might have the benefit of your advice regarding the whole program as soon as possible. However, I myself shall probably be away from Pasadena for about a month on a war problem, so that this may make a complication.

  Please write to me soon.

  Sincerely,

  Linus Pauling
