  Dr. Warren Weaver

  The Rockefeller Foundation

  New York, New York

  Dear Dr. Weaver:

  I am enclosing my report on the work of Dr. Dorothy Wrinch, resulting from her visit to Ithaca on January 26th and 27th, 1938. You will see that my impression of her and her work is in general an unfavorable one. I believe, however, that my conclusions are justified. I am sympathetic to the application of physical and mathematical methods to chemical and biological problems, and I began the interview with Dr. Wrinch with the hope that the unsatisfactory aspects of her published work would be removed in the discussion. I found, however, that her methods and results are still less scientific than they had appeared to be from her papers.

  I doubt that her attack on the problem of protein structure will lead directly to any valuable results, and I think that it would not be worth while to have her working in our laboratories in Pasadena.

  In this report I have written my opinion without reserve. I would not write so freely for publication, of course.

  Sincerely yours,

  Linus Pauling

  Dr. L. E. Sutton

  1, Eastchurch

  Iffley, Oxford, England

  Dear Sutton:

  I am astounded to note that your letter of the 9th of February remained unanswered this long. This may be due in part to the visit of Todd, who with his wife left on the Grand Canyon Limited just two hours ago on their way back to London, and in part to the first steps of moving into the new laboratory. I was interested to read about your dream and to put you in bettor shape for further dreaming, I am enclosing a clipping from the Los Angeles Times.

  Having got this far in the letter, I decided that the time had come to move from Astrophysics to Crellin so my secretary, Mrs. Shaffer, and I picked up some pencils, paper and the typewriter and made the move.

  I have a nice big laboratory in the north east corner on the first floor of Crellin, the situation being the same as in the Astrophysics Building. This laboratory is twenty feet square. It has two chemical desks and a hood and sink in one corner, a writing desk and table and a black board and a blue rug on the floor under the writing desk. Next door is a smaller room about ten by fifteen, containing a writing desk for me, for business, a desk for the secretary, and miscellanies. To the west is a large room about twenty by thirty, which will contain Weinbuam, crystal models, plotting tables etc. I do hope that you will come to Pasadena again on your next leave of absence from college.

  Hampson and Springall have been working very hard this spring and I think that they will finish up their work in fine shape. I heard from the Commonwealth Fund that a man named Laidler is applying for a fellowship. I would be glad to have any of your able men come here to work, even including those in organic chemistry, since we are developing our work in this direction.

  Brodkway has just sent me a copy of his paper on the phosphorus compounds. He seems to have been enjoying himself very much at Oxford.

  I am sorry that I am not coming to England this summer, and I hope that a European trip can be arranged before too many years have gone by.

  With very best regards, I am

  Sincerely yours,

  LP/bcs

  April 20, 1938

  Dearest sweet little wife:

  I love you, darling, and I'm happy to be your husband. You are the sweetest girl in the world. I like to read the letters that you wrote to me at Cornell.

  Today I worked on my book for a while (correcting old chapters). I gave my lecture this morning, and listened to Rabinowitsch this afternoon. Dr Lacey asked if I thought that Swift should revise Noyes "Qualitative Analysis". It still earns (for the Chem. Div. now) about $1000 a year in royalties.

  I am looking forward to going on a nice ride with my little love tomorrow. Now I am going to work on my book.

  Be happy, my darling little wife.

  Your own

  Berkeley, California

  Dear Professor Lewis:

  I am enclosing a photograph of my drawing of the water molecule, and I hope that you can make use of it. The drawing is based on the calculations made by Coolidge. The scale is given by the O—H internuclear distance of 1.96 Å.

  Ava Helen and I have been hoping to come to Berkeley for a visit but I am afraid that it must now be put off until June or July. With best regards, I am

  Sincerely yours,

  Linus Pauling
