STANFORD UNIVERSITY SCHOOL OF MEDICINE 2398 SACRAMENTO STREET DEPARTMENT OF PEDIATRICS SAN FRANCISCO 15, CALIFORNIA J y : ‘| October 14, 1958 Dr. Joshua Lederberg Department of Medical Genetics Genetics Building The University of Wisconsin Madison 6, Wisconsin Dear Doctor Lederberg: I cannot thank you enough for the tremendous help you have given me in making my plans for next year. You have enabled me to arrive at a decision which I think will be a very happy one for me personally and which should enable me to have a most productive year of study. I feel that, although several people are doing very exciting work in the field of genetics, none of them can offer me any more, if as much, than I will be able to get at Stanford from you and Art Kornberg. Therefore, it seems most logical that I should spend the year trying to achieve as basic and broad an approach to the field as possible. Under these circumstances, I am sure I should be most happy to spend a major part of the time with Dr. Cavalli. I have just received a very cordial letter from him, which completely removed any lingering doubts I might have had. Perhaps it would be possible for me to spend nine or ten months with him, and then spend two or three months visiting London, Cambridge, Paris, etc. In this way I would get a flavor of what some of the other people are doing, but would get my basic instruction from Cavalli. I have just submitted my application to the Guggenheim Foundation, and will follow it with applications to Commonwealth and the U. S. Public Health Service. I would be very grateful, if I could list your name as one of my references in these applications. I realize that you do not know me personally, nor have you had any first-hand knowledge of my work. I know, of course, that your support would lend tremendous weight to these applications, and I would be most grateful to you, if you are willing to give it, I am delighted to know that you may be in San Francisco in January. I lock forward with the greatest of pleasure to meeting you at that time. In the meantime, I want to once again express my heartfelt thanks for your enthusiastic reception to my plans and for all the help that you have already given me. Sincerely yours, Ruth T. Gross, M.D. Associate Professor in Pediatrics Acting Executive RTG: jb
