LABORATOIRE DE BIOPHYSIQUE UNIVERSITE DE GENEVE Quai de I’Ecole-de-Médecine 24 Genéve, le 28th November 1958 Professor J. L&D ARBERG Department of Genetics University of Wisconsin Madison 6, Wisconsin U.S.A. Dear Prof. Lederberg, Thank you very much for your letter. I am still very interested in a visiting trip to the States and plan seriously to organize it for next year. I am extremely hanvy that you may possibly find some help for the realisation of this nroject. I do not yet know the most suitable months; perhaps the summer vacation veriod, which would be best for me, may be not well suited for the visit of laboratories in the States. Would June-July be better? I would be extremely glad to- visit Stanford? I thought to visit also the laboratories of Hershey (Demerec), Luria, Watson Levinthal, Anderson, Williams and Del brtick- Dulbecco. Considering more durable arrangements, I must say that I am still unfixed in my mind. It is true that my own position and that of my laboratory may become established soon. All mommittees agreed in pronosing a professorshin ("extraordinaire") with the direction of the laboratory. The government has now to satisfy this and pronose a salary. All this does unfortunately not create the missing general scientific atmosvhere at our university where the project of creating a center of virology and microbiology was not accepted (too exnen- sive) Needless to tell you how glad we all were, when we heard that you received the Nobel vrize ! This gives us the hapvy feeling, that the sort of research you initiated all over the world made a path forward to be generally accepted ! You may know that in Eurone, most vrofessors of Zoologie and Bo-~ tanics ("suecédané" of Biology) don't know anything about bacterial and virus genetics, or have just heard some rumors which are accepted with highest scentie® cism ! I thank you very much for your kindness and send you and your wife my best regards, Yours sincerely C ptevaol EB. Xellenberger
