  Huntington Memorial Hospital and USC School of Medicine. The Third Willard J. Stone Memorial Lecture

  "Medical Research of the Future," by Linus Pauling.

  Pasadena University Club. April 2, 1946.

  Ladies and Gentlemen: I am greatly honored to have been invited to give the 3rd Willard J. Stone Memorial Lecture, and it gives me a deep feeling of satisfaction to be able to take part in a ceremony honoring Dr. Stone, and through him all of the men of medicine upon whom so much of our welfare and happiness depend. I feel especially grateful to you for inviting me, somewhat of an outsider to the field of medicine, to meet here with you. I am reminded of a story in the autobiography of Dr. Walter Cannon, the great physiologist of the Harvard Medical School, who overheard a girl say to his daughter "How many patients does your father have?" And the daughter reply [sic] "Oh, he doesn't have any patients - he is one of those doctors who don't know anything."

  My title is "medical research of the future"; and as the future is the extrapolation of the past, let us look first at the past. In Shakespeare's time there were "The rotten diseases of the south...." Some progress was rapidly made - I haven't heard of the fee simple of the tetter in more recent centuries. And there has been medical research and consequent progress in recent years. From 1900 to 1942 the life expectancy in America increased from 49 to 65, largely as the result of decrease in death rates of infants and children - in the last 20 yrs the death rate from children's diseases has decreased 87% - scarlet fever down 92%, whooping cough 74%, measles 91%, diphtheria 94%!

  This has made the malignant diseases and degenerative diseases more and more important. Cardiovascular diseases now cause 45% of all deaths. Next the infectious diseases, with cancer a close third; and there are many diseases (common cold, arthritis, hay fever, peptic ulcer) which cause incalculable disability.

  There was great progress made during the war - not on cancer and cardiovascular disease, but mainly on the infectious diseases - there was the production of penicillin, of dried plasma. I want to point out that this progress depended on basic research done before the war; and now we have used up the supply of basic discoveries. X-ray diagnosis and therapy followed the accidental discovery of x-rays by Röntgen in 1895 - and x rays were used in a hospital within three months. Penicillin was discovered accidentally by Fleming in 1929 and its value proved in 1937 by Florey and a $5000 research grant from the Rockefeller Foundation. Blood plasma was dried by Flosdorf and Mudd in 1935. The war just put these discoveries into use.

  Why can we not attack cardiovascular disease and cancer effectively? First, until recently there has been no money - $2 per death for research in cancer, 21 cents per death for cardiovascular disease. But mainly there have been no leads to follow, no hints from basic science - our knowledge of cell division is not great enough, of vasoconstriction and vasodilation. The great need of medicine is in this fundamental region.

  Let me illustrate what can be done by telling the story, which some of you have heard, of the work on a blood substitute. (Dan H. Campbell, Joseph B. Koepfli). ----.

  Now in this case we knew pretty [well] what was needed and how to fill the need. In cancer and cardiovascular disease and poliomyelitis and arthritis we do not know enough - and it is astounding that the gap in the region of knowledge is so small and yet so important. The dark forest of the unknown extends between 10^-6 inches and 10^-7 inches - and it is in this little region that all the secrets of life and death are hidden - the gene, viruses, enzymes, causes of cell division, structure of proteins.

  Let us imagine ourselves 250,000,000 times bigger, in height equal to the moon; and looking at an organism, New York City. --- ---

  This, then, is the situation - the future of medical research depends upon the future of basic science, and its effectiveness in penetrating into this little strip of the dimensional forest. We in California should help - another medical school. with research on the $500,000 scale instead of $10,000; use of the great supply of clinical material at Los Angeles General Hospital; and use of the California Institute of Technology - where there are men with a mastery of basic sciences, interested in turning their attention to these problems fundamental to biology and medicine. Let us hope that progress can be made in solving the secrets of life and death.

  Walt Whitman: "The two old simple problems, ever intertwined, close home, elusive, present, baffled, grappled by each successive age insoluble, passed on to ours today - and we pass on the same." And let us resolve that as we pass on the problems to our next generation we shall pass on also our contributions to their solution.

  Dear Selfriz:

  It is a pleasure to hear from you once in a while, and perhaps some time I shall be able to write an article for the planned JOURNAL OF PROTOPLASM.

  I am very much interested in the structure of proto-plasm and I wish that I knew more about the facts which have been gathered that are pertinent.

  It is very easy to answer your question, about the Heitler-London bond. This bond is indeed very important in biology, and also in chemistry—it is, in fact, nothing more than the shared-electron-pair bond of Gilbert Newton Lewis, which is itself, of course, the structural feature which is usually represented by the dash of the organic chemist. I have not read Schroedinger's little book, but I am not surprised that he is somewhat confused by these points, because he has never paid very much attention to chemistry.

  By the way, I do not think that you should speak of the "Pauling hydrogen bond". The hydrogen bond has a considerable history during the decade or so before 1928, when I became especially interested in it.

  Sincerely yours,

  LP:par Linus Pauling

  Dear Mr. Maccoll

  Your manuscript has now been found, among some other papers in my laboratory, and I observe that it is marked received September 11, 1945 and, moreover, I see that my negligence is far more serious than I had thought hitherto, because in your letter of July 17 you ask me to forward the manuscript to the Journal of Chemical Physics. I apologize for having failed to do this.

  I am not now sending the manuscript on to the Journal of Chemical Physics, because of the remark in your letter of March 5 that you are planning to publish it in the Journal of the Chemical Society. If you have not yet submitted it, and you would prefer to have it appear in the Journal of Chemical Physics, please let me know at once, and I shall send the copy which I have to the editor.

  I have read the manuscript with interest, and I think that it is worthy of publication. I find it difficult to decide about the reliability of the simple calculation when applied to such complex phenomena; that is, in the interpretation of the difference in energy of two stationary states — I believe that the application to the calculation of resonance energy alone is somewhat more reliable. The only feature of the work which surprises me is the very small value, 0.20 v.e., of the nitrogen-nitrogen integral y. It is true that the energy of a single bond between two nitrogen atoms is very small; but the very great energy of the triple bond, in the nitrogen molecule, indicates that the exchange integral y is very large rather than very small.

  I trust that you will continue to work in this interesting field, and I shall look forward to hearing from you again, and to meeting you at some time in the future.

  Sincerely yours,

  Linus Pauling

  Pasadena

  24 April 1946

  Dearest Mom and Dad,

  On April 22, 14 hours, 49 minutes, 30 seconds, I became once more a civilian. A very happy occasion. I hitch-hiked up in 12 hours flat, which you will agree is phenomenal since Beale is 60 or so miles above Sacramento. And only 45 hours after arrival I walked out free. And I got back here Tuesday morning, early enough to send the kids and Arletta off to school so I could take an uninterrupted nap.

  Affairs are proceeding here very smoothly. Arletta wants to stay, I think, so I told her we'd be glad to have her. J.H.S. came for supper last night. Taka and I seem to be keeping going. I have trouble keeping track of the house and garden because I'm not familiar with the routine yet.

  Your gardener Fred came up before I left and delivered an Easter plant for you, some amazing creation with brick red leaves shaped like this:

  Birds, plants, rabbits, and chickens are all doing well. We're having trouble with thick smog, though. It isn't nearly so nice here as it is all the way north from the Ridge. Sacramento was too hot for comfort. Very nice here as for as temp. goes.

  All my love, and best wishes for a good time for you. I hope those theatre tickets were satisfactory.

  Linus

  P.S. Say hello to Mae for me.
