  Prof. N. V. Sidgwick

  Lincoln College

  Oxford

  England

  Dear Sidgwick:

  I am writing to send our best wishes to you, and to tell you how we are getting along.

  The inspiration for writing you came this afternoon when I got down your book CHEMICAL ELEMENTS AND THEIR COMPOUNDS to check up on the chemistry of sulfur, and noticed again the kind reference that you make to me in your preface. When you prepare a second edition of this book I hope that you will allow me to give you my suggestions about every chapter. They would not be numerous - I can't say that I have found anything wrong; but I would like to be of help to you.

  I note that you do not say anything about Aten's sulfur pi, which Ephraim discusses in some detail. Apparently Aten thinks that sulfur pi consists of S₄ molecules. Ephraim says that it cannot be S6, because it is more deeply colored than S₆, and also is four times as stable(whatever that means). (I note that Ephraim says that S₆ is about four times as stable as S₄, rather than the opposite.)

  Ava Helen and I have just returned from a trip to Philadelphia and Washington, where we attended meetings of the American Philosophical Society and the National Academy of Sciences. We saw Wyckhoff in Washington - I was very pleased that he was elected a foreign member of The Royal Society.

  We also stopped at Minneapolis, Urbana, and Detroit, and I spoke at meetings of the local sections of the American Chemical Society at these three places.

  No doubt you noticed that Larry Kimpton has been chosen as Chancellor of the University of Chicago. You remember that he was Dean of Deep Springs at the time you visited there about fifteen years ago. The people at Chicago seem to be well satisfied with his selection as the successor to Hutchins. I think that he does not have Hutchins' extraordinary originality, but he seems to show very good judgment in all of his decisions.

  Professor Sidgwick

  Corey and I are publishing a series of papers on the structure of proteins. One of than is coming out in the April issue of the Proceedings of the National Academy of Sciences, and seven more in the May issue. In these papers we describe quite exactly a number of alternative configurations of the polypeptide chain, in which the interatomic distances and bond angles have the dimensions found for simpler substances, the amide groups are planar, and the carbonyl and imino groups are involved in hydrogen-bond formation. There are only a few configurations discovered so far that satisfy all of these conditions. We have very convincing evidence, from x-ray diffraction photographs, that these configurations are represented in proteins. In our papers we describe the structure of stretched muscle and contracted muscle, and discuss the mechanism of contraction. Stretched hair and ordinary hair have similar structures. Moreover, we have found the structure of two synthetic polypeptides — these, like ordinary hair and contracted muscle, involve a helical configuration of the polypeptide chain. The structure of collagen and gelatin is a very extraordinary one - the molecule consists of three polypeptide chains coiled about one another, like the three strands of a rope, these three chains being held together by lateral hydrogen bonds. Feather rachis also seems to have an interesting structure, involving a sheet of nearly extended polypeptide chains (with, however, a configuration different from that usually assigned to B-keratin), and then a double layer of helical molecules, followed by another sheet, another double layer, and so on. The helical structure of ordinary hair is also present in the hemoglobin molecule. I am sure that these discoveries will introduce a new era in the protein field.

  Our boy Peter did not succeed in carrying through his plan of studying at the University of London. He had arranged with Coulson to be accepted as a physics student at King's College, but the University of London would not accept his credentials. (He had finished his sophomore year in physics at the California Institute of Technology.) So he returned home late last September, and began his Junior year here. I think that he will now finish his undergraduate work here, but it may be that he will come to England for graduate work.

  I am not sure that we had told you that we have a swimming pool now, just about 30 feet in front of our house. It is elliptical in shape, with axes 20 feet by 46 feet. It is equipped with a heater, and we have kept the water warm enough to permit us to swim nearly every day this winter. I had a swim a couple of hours ago. Since then it has been raining, and, in fact, some hail stones have fallen. We have had a dry winter, and are pleased to have some rain this late in the season.

  Professor Sidgwick

  I had a letter from Jenkins last month. He wrote that he was hoping to get a full-time job in chemistry, because he was not able to support his family on his theological income. I wrote a testimonial for him, and sent it on to him. Did I ever tell you that in one of the notebooks that he left with me he had written some notes for a talk that he was preparing (perhaps to be given after he returned to Oxford), and he described Southern California as "theologically retrograde."

  I am not going to come abroad this summer. I had planned originally to attend the International Congress of Crystallography in Stockholm, but then I changed my mind, feeling that I would rather stay at home. I travel a good bit anyway - next week I am going east to take part in the dedication ceremony of the new DuPont laboratory and of the research building of Massachusetts General Hospital, and on May 25 my wife and I are going to fly to Hawaii, where I shall speak before the local section of the American Chemical Society and other scientific groups. We have not been to Hawaii before, and we are looking forward to our ten days there.

  With best regards, I am

  Sincerely yours,

  Linus Pauling:W

  Dear Dr. Ambrose:

  Professor Corey and I have been very much interested in your work on synthetic polypeptides and fibrous proteins, and we are publishing several papers in which the work is discussed, in relation to the configurations for polypeptide chains that we have formulated. Our configurations all conform rigorously to the structural requirements that we have found to be satisfied in staple substances. We note that you have expressed doubt as to the importance of some structural features, such as the planarity of the amide group. We think that the amount of evidence is so great that there can be no question about the instability of configurations involving significant deviation from planarity of this group, and that progress in the protein field will be made through the search for structures in which the amide groups are all planar.

  Two of our polypeptide configurations are described in a paper in the April issue of the Proceedings of the National Academy of Sciences, and others in seven papers that are to appear in the May issue. We have felt especially pleased that the structures that we assign to synthetic polypeptides, β-keratin, α-keratin, and collagen involve orientations of the N-H group and the C=O group that correspond closely with those that you have found through your infra-red investigations.

  I am writing now to ask if you have observed any dichroism in feather rachis keratin in the plane normal to the fiber axis. We have assigned a structure to feather rachis keratin that consists of β sheets alternating with doubles rows of α helixes. If we assign axes a, b, and c such that c is the fiber axis direction (the direction of polypeptide chains in the β sheets and of the axes of the α helixes), and the a-c plane is the plane of the β sheets, then we would predict that the hydrogen bonds of the α helixes are nearly parallel to the c axis

  Dr. Ambrose

  and those of the β sheets are nearly parallel to the a axis. Our structure requires that there be 3-7 hydrogen bonds in the c direction for every two hydrogen bonds in the a direction, with essentially no component along the b axis. I assume that your measurements relate to dichroism in the a-c plane. Do you have any data about dichroism involving the b axis?

  Sincerely yours,

  Linus Pauling:W

  Mr. Parks

  May 18, 1951

  Charge on x-ray tube

  Dr. Shoemaker has told me that an inquiry has come to him from the Business Office about one Machlett x-ray tube insert (copper target), with regard to inventory of Navy Capital Equipment. The Navy identification number for this tube is 91726-081,001, serial number F-2661, and was acquired on March 23, 1950.

  This tube should not have been classified as capital equipment. The only other x-ray tube that to my knowledge was purchased with N6onr-24432 (Chemistry 27) funds was classified as expendable, as were two Kenotron rectifier tubes. X-ray tubes and rectifier tubes have no value after the filaments have burned out, and the filament may be expected to burn out after approximately 1000 hours of service. Provision for purchase of x-ray tubes was made in the budget for our Navy contract to cover the tube cost of the total x-ray exposure time expected under the contract. Such tubes should therefore be considered as expendable items.

  Would you please request the Navy to reclassify as an expendable item the tube mentioned above?

  Shurei Hiroza - Star Bulletin 10 AM Sat May 26.

  Hugh Lytle of Advertiser 11 AM Sat. May 26, '51

  Halekulani / Honolulu 15, Hawaii

  From my general knowledge I feel sure that a hydrogen bomb can be made.

  I feel strongly

  The Board of Regents made the wrong decision about me and was stubborn about reconsideration. I offered to come at my own expense to appear. The offer was refused.

  I wrote one member of the Board (who might, I thought, be the best man on the board), in the hope that he would help the Board to reach a reasonable solution. His answer showed great bias - he said that he would vote against reconsideration, 3 weeks before the meeting at which the evidence was presented!

  To Lytle

  I would have ignored the action of the Regents if it were not for the ill-bred way in which it was announced (to the press, several days before me)
