ily COMMONWEALTH SCIENTIFIC AND INDUSTRIAL RESEARCH ORGANIZATION - DIVISION OF PLANT INDUSTRY OHF.MS CABLE AND TELEGRAPHIC ADDRESS: BOX 109, CITY P.O. “CORESEARCH,” CANBERRA, A.C.T., CANBERRA AUSTRALIA llth June, 1957 Professor J. Lederberg, Department of Genetics, University of Wisconsin, Madison 6, WISCONSIN, U.S.A. Dear Dr. Lederberg, As you know, the Genetical Society of Australia has its annual meeting on the two days following the symposium on microbial genetics in Canberra. The Society would be most grateful if you could give to the meeting an evening address. This would take place on the night following the symposium and therefore on the first evening of the Genetical Society meeting. on that night we usually have an address either by a distinguished visitor or by a newcomer to Australia, and it would be very fitting indeed if you would agree to give the address this year. On this occasion, in view of the wide interest of the subject, we propose to make this open to the general scientific public and whilst you would address yourself mostly to geneticists - we expect some 40 or 50 members of the Society to attend - it might commend itself for the address to be perhaps of wider interest than would be appropriate to a purely genetical audience. There will be no need to be "popular", but perhaps it would be advisable to be less genetically technical. we here are looking forward with pleasure to your and your wife's visit and I hope that your stay in Australia will be very profitable and pleasant. I am in close touch with Professor Fenner regarding arrangements for your Canberra visit and you will hear from him shortly regarding some suggestions which we discussed a day or two ago. With kind regards, Yours sincerely, eo C, KA wre. Ay ~~ (O.H. Frankel)
