THE ROCKEFELLER UNIVERSITY 1230 YORK AVENUE NEW YORK. NY 10021 TOSHUA LEDERBERG PRESIDENT 2 October 1987 Ronald G. Crystal, M.D. 3746 Cumberland Street, NW Washington, DC 20016 Dear Ron: As you recall from our telephone conversations last May, my colleagues and I were stymied in developing an offer to you that would be consistent both with our prior- ities and resources as well as with your current support and your forthrightly stated aims. Despite our (now seem- ingly forlorn) hopes during our conversations with you be- tween the fall of 1986 and the spring of 1987 -- and we greatly appreciated your cooperation in these lengthy dis- cussions -- we were compelled to conclude that your poten- tial transition here would be much more difficult than we had first visualized. Further inquiries at Cornell clarified that, while you would be warmly welcomed as a member of the Pulmonary Division, the Department of Medicine could not offer re- sources such as space, funds, and paid fellows specifical- ly assigned to you. These constraints on the development of your proposed programs thus compounded those imposed by our own limitations. ‘ I should perhaps have written to you earlier, and more formally, to Say how much we regretted this conclu- Sion. Still I trust it is not too late to tell you of our warm respect for you personally and our very great regard for your professional achievements. We wish you well and hope very much that your vigor- ous research program will continue to be aS productive as it has been along so many fronts, You engendered the friendship of all who met you here at the Rockefeller, and we deeply regret that it was not feasible to conclude our negotiations at the high level of anticipation with which they began. I hope we can continue to meet to discuss scientific matters despite the closure of these discus- sions about relocating your labs. bec: Jan Breslow, M.D. Sincerely, Attallah Kappas, M.D. Rodney W.
