Professor Harold C. Urey

Department of Chemistry

Columbia University

New York, New York

Dear Professor Urey:

I can recommend strongly to you for appointment as Instructor or Assistant Professor in organic chemistry at Columbia, Dr. Saul Winstein who took his Ph.D. here in 1938, was post-doctorate research fellow for one year, and has been at Harvard this year as National Research Fellow. Winstein has been recommended by the Harvard people for appointment as a Fellow in their Society, and has also applied for a Lalor Fellowship, but I think he would prefer to have a teaching appointment. I am enclosing a copy of a letter which I wrote about him to the Society of Fellows. I want to emphasize to you that Winstein is a very pleasant and friendly person and, indeed, was as well liked here as any man whom we have had.

We have not had recently anyone taking a doctorate with his research in the analytical field. I suggest, however, that you consider for appointment as Instructor to teach qualitative analysis and physical chemistry, Dr. David P. Stevenson, who came here in 1938 as National Research Fellow and has remained this year as post-doctorate research fellow. Stevenson worked with Eyring and Beach at Princeton and here he has done electron diffraction work, having completed a number of very interesting investigations. He has taught qualitative analysis and has had a good bit of experience in quantitative work. I think that he is a very good man, with broad interests, and with the ability to adjust himself to any position in which he might find himself. I am sure that he would make a success of the work with you, and he has told me that he

would be interested to have the appointment.

I have not asked either Winstein or Stevenson to write to you directly.

Sincerely yours,

Linus Pauling
