  CALIFORNIA INSTITUTE OF TECHNOLOGY

  PASADENA 4

  August 18, 1944

  Dr. Warren Weaver

  The Rockefeller Foundation

  49 West 49th Street

  New York, New York

  Dear Warren:

  When I was in New York in February I mentioned to Dr. Hanson a plan for post-war research which I have been thinking about recently. I am now outlining this plan to you in order that I may have the benefit of your advice.

  Dr. Robert B. Corey and I are supervising a war research project at this Institute on which about forty chemists, with Bachelor's or Doctor's degrees, are employed. The work which is being done is in a large part pretty respectable scientific research. We have an organization which is now working with extreme efficiency. The men carry on their work under a system of orders and reports; orders for individual investigations are issued by Dr. Corey, and the investigators then prepare reports on their work.

  I suggest that, when the war comes to an end and presumably a large number of well-trained young scientists will be looking for employment, we set up a research project designed to operate in this same efficient way, for the purpose of making a very vigorous attack on the problem of the structure of proteins and related substances.

  We have available in the Gates and Crellin Laboratories apparatus for x-ray investigation of crystals and the determination of the structure of gas molecules by electron diffraction. We also have a set of punched cards and punched card machines for carrying out the numerical calculations that are necessary in x-ray and electron diffraction work in a far more efficient way than has been available hitherto. The years of experience which we have had in the x-ray field, with especial attention paid to the protein problem in recent years, provides us with sufficient background to enable us to make plans for a research program which will without doubt provide a great amount of information. We know what can be done by diffraction method?—we know that it is possible to determine in complete detail the structure of crystals of amino acids, peptides, prosthetic groups of proteins such as the heme group, and other relatively simple substances related to proteins, and that also a great deal of information presumably could be obtained about proteins themselves, by direct attack. We also know that the amount of labor required to obtain this information is very great, and that progress will be correspondingly allow unless more vigorous methods are used than have been used in the past. Dr. Corey, working full-time, with the aid of one assistant, was able to make a complete structure determination of an amino acid crystal in between one and two years. I believe that, with the aid of the labor-saving devices which we have developed, a well trained full-time research assistant working under careful supervision could be expected to carry out an equivalent job now in about one year. The essence of my plan is that we would have perhaps twenty such research assistants working on a unified program under the direct and detailed supervision of Dr. Corey, Professor J. H. Sturdivant, Dr. Verner Schomaker, and myself, with the labor apportioned among the research assistants so as to get the work done in the most efficient way.

  In addition to this structural work, we would make studies of porphyrins and their metal gaits and other prosthetic groups of conjugated proteins by chromatographic and spectrophotometric methods, would carry out investigations of various physicochemical properties of hemoglobin and chlorophyll, and would use all appropriate techniques for learning at much as possible about the nature of these important substances and others of biological significance.

  The program which I have in mind is, then, one which involves a staff of perhaps twenty full-time assistants, including people with Bachelor's or Doctor's degrees, a couple of typists to take care of the orders and reports, and computers and routine assistants. The project would presumably begin immediately after the end of the war, when men are being dropped from OSRD projects; it should, I think, continue for at least three years. The cost of the project for a three-year period would be approximately $150,000.

  I am enthusiastic about the possibilities for fundamental scientific progress which this plan affords. The protein problem is a great one, and its solution will not be easy. This plan is not going to solve the problem. I think that the problem can be solved only by a very great amount of very hard work. We know enough about the experimental methods of structural chemistry to be sure that a large amount of progress can be made by applying these methods, and we know that the progress will be made only by putting in a great amount of effort; my proposal is that this effort be applied in three years, instead of in twenty.

  I shall be very glad to know whether or not you think that this plan is a sensible one. Do you think that it would be worth while for the California Institute of Technology to submit a request to The Rockefeller Foundation for a grant, to be made for the purpose of carrying-it out? If so, would it be appropriate for the request to be made before the end of the war, in order that the plan might be put in operation immediately at the end of the war?

  I shall be pleased when it again becomes possible for me to-see you occasionally and to talk to you.

  Sincerely yours,

  Linus Pauling

  Truax Field

  Tuesday August 22 [1944]

  My darling Paddy:

  I have had one night here at the Field but spent Sunday night with the Williams since young Linus could not get leave enough to meet my train. The Williams met me and were very sweet. Linus came at four yesterday and we came out here to the Field.

  This morning I wakened at 9.30 or so because of a lot of singing, band playing, etc. and looked out of my window to see company I marching by in fatigues — each group singing a different song and the band playing, too, in its own independent way.

  Linus spends what free time he can get with me which isn't much. He is the same moody, antagonistic towards his environment, morose boy who looks awfully tender and young. His hair has grown very much redder and he says he is even called "Red"!!

  If I could only help that boy! Two people, strangers, have asked me "Is that your son? He sure looks like you."

  I had a dreadful time getting on the train. The worst experience I think I've ever had. Still I learned a good bit and everything was interesting. However my red cap never reached the train or me, with my bags and so they were put in the lost and found and I didn't get them until yesterday — Luggage Trouble Lulu!! Now you'll say I shouldn't have given my checks to a Red Cap — but I would never have even gotten them out of the parcel room if I hadn't because although I was there at 5:00 there were already 200 [star] (hundred) ahead of me in line to get bags. Moreover, I went up to stand in line at gate 6 for my train at 5:20. My Red Cap told me to go then and there were 300 people already there and 500 more were soon behind me pushing - So - [star] - That extra hundred was the way the crowd appeared to me to be in size.

  What an experience! We must never arrive in Chicago on Sunday again. We should have known better.

  I have our return seats. I got them yesterday when I went for the bags.

  Young Linus no longer has Tuesday off but has Saturday instead. He took kindly to my idea of a day with us in Chicago although I offered it (after my experience) without enthusiasm, but it isn't possible now. I wish you could be here Saturday which is his free day.

  I shall go to the Daniels on Thursday and then on Friday we will get Linus and all go to dinner. I will be hostess and Linus will stay overnight Friday at the Williams and we'll have Saturday. Then we'll get you on Sunday and we'll go to the Williams. I wish you could stay here at the Camp for you'll not see Linus I'm afraid. Perhaps a bit on Sunday.

  I must write to the children at home now.

  How are you and are you getting along well? I hope everything is going along well.

  I love you very much.

  Your wife,

  Ava Helen

  P.S. The news yesterday was to the effect that Patton had crossed the Seine and was moving north and west to the robot [?] platforms. Good! I haven't heard any today. Linus looks well. His face is clear but his lips are chapped and sore. He said they were one of the things he'd inherited from me!!! Instead of saying and thinking "Thy will be done" this coming generation says and thinks — "I am Inheritance." Perhaps some such explanation is necessary. Linus is awfully sweet and tender and quiet and genuinely happy to see his Mother, I believe. These poor helpless bits of humanity.

  AP.

  Monday night

  Dearest love:

  I hope that my telegram hasn't surprised you too much.

  Did you get along all right in Chicago and on the train? I walked fast the Dearborn station; then I was hot, and afraid that perhaps the remaining time (14 minutes) was too small, so I took a taxi to the B&O station, and thus arrived with nearly 10 minutes to spare. I got to Washington on time (8:45 AM ), went to the hotel (Lee Sheraton), and then to the British Liaison Office and to Chadwell's office (fiv [?] .19 of the NDRC). He wants me to think about a special problem, one which Lamb is working. If we about go to Cambridge I might have to come back East again in a month or two - I'm not sure that I can be helpful. We shouldn't mention to anyone that this new problem has come up, nor that Lamb is involved.

  Then Gus Hamar and Reuben Wood took me out in the country to their place, which was very interesting. Pitzer was there, and Reuben, Pitzer, Mrs P and the three little P's and I went to dinner together. The Pitzers are going back to Berkeley in a month or so.

  Then Reuben and I called on Sterling and Edith. E's mother is there. I saw some pictures of the baby - she looks cute. Then I came back to the hotel.

  I might have some trouble keeping things going in the lab if we were to stay in the East for a whole month (several days in Cambridge, and then several in New York). Also I'm worried about the Cranshaw melons and other things in the garden. Perhaps we shouldn't try to stay.

  Give my love to Linny

  Your

  Dearest love:

  Your telegram has arrived. I am just as happy as if your decision had been for us to stay — and I think that this may be better. I wanted, however, to give you the chance of attending the New York meeting.

  I may have to come East again in a couple of months to handle this new & ultrasecret job.

  I didn't get much done today — Tohman, Keefer, and Wearn were all out of town, but I talked to some other people at CMR. Tomorrow will be a full day for me. I went back to see Sterling and Edith tonight — I had forgotten my brief case there last night. I saw their baby — a cute little 6-months old! She wouldn't drink her milk while I was there, but drank it when Edith took her back to her room. Edith's mother is there — she is a smart old girl.

  Well, I'll be seeing you in a few days. Love to Liny. [?]

  [1944]

  Dear Paddy:

  You rascal--sending me such a telegram! I was sorely tempted by the prospect of Cambridge and New York. (As you thought I would be, but Ha Ha I fooled you!) but I couldn't decide to come with you even though I want to so badly.

  However you, of course, must go and do the job if you are needed.

  It is 2 pm and Linie is with me. We have had lunch together at the Service club and he is here reading the H.G. Wells.

  Last night he brought his friend Robert Smith who is a wonderful looking boy and a good looking boy, too. We all three had supper and then walked about a bit.

  It is grand fun being here on the Field. I wouldn't miss it for anything.

  Early this morning we had a fine thunder storm-the rain sounded like tons of gravel being emptied on the roof from some celestial dump truck. Today is cold and wintry-with wind and enormous cumulous clouds-my suit none too warm.

  Again I feel young Linie's antagonism

  [page 2]

  towards life in general. What a lad! He said the 2^nd Lieutenant had come in the class and glared awhile but that he had glared back. He had a run in with the 2^nd Looy yesterday too. I'll tell you about it. I said to him that a sweet tender face like his couldn't glare very successfully but that, of course, he could always try. He laughed. According to his buddy Smith everyone tells him about his wonderful blue eyes!!

  Where have we heard that before?

  Good by for this time you rascal. I hope this reaches you.

  Hugs and kisses

  from your girl,

  Ava Helen

  I'll not write again.

  See you Sunday.

  Thursday night

  Dearest little love:

  Your two letters arrived today to make me happy. I am glad that you are having fun with Linus - but what a shame that you underwent such an excruciating experience on the train! I hope that you had a seat. I should have written to Phoebe to get a ticket and reserved seat for you. I traveled on the same train a few months ago, and had no trouble (I rode in the coach), although the train was crowded - but of course Sunday is a worse day.

  I hope that Liny doesn't make trouble for himself by being antagonistic. He must learn to put himself in the other person's place, and to understand the variety of past experiences and natures which caused people to behave in various ways.

  The weather has been mild here - I went to dinner with the Tolman's and their brother Ed at their house last night, and had a fine time. I borrowed Richard's rain coat to come home in, because it rained. Today has been rather cool - my suit is none too warm.

  The special trip was to have been about a new, important, and highly secret problem, not to be mentioned to anyone. But I have had an idea as to solve it, and shall work on it at home.

  Today I talked to Richards, who is a fine old fellow, about an oxypolygelatin and about the blood substitute problem in general. The great need is in China, where they have no plasma for the Chinese. Some gelatin solution is being sent over; but I think that our oxypolygelatin, perhaps in 10% solution, would be better - and perhaps it could be made in China, from materials send [sic] by plane - a 20-fold saving in space.

  In the afternoon I went to the Pentagon, and then on to Milt and Dorcas's. Milt has not worked for six weeks - he had an attack of Bell's palsy, which paralyzed the left side of his face. He has recovered somewhat, but it is still noticeable.

  He was planning to give some money (50 or 100$ each) to each member of the family + get a release of any claim to the duplex. I urged him not to do so - if his legal rights are satisfactory, he needs no releases, and to try to get them is to invite trouble; also, I think that he may need the money himself later. Dorcas is well + chipper.

  I love you, darling. I'll be glad to see you and Liny.

  Your own
