ISTITUTO DI GENETICA December 3, 1958 VIA SANT’ EPIFANIO, 14 PAVIA TeELBFONO: 23.029 Dr. d e Lederberg c/o Prof. G. Klein Dept. of Tumor Biology Karolinska Institutet STOCKHOLM 60 Dear Joshua, We shall soon have more opportunity to discuss the Stanford prograume. Meanwhile, let us settle the more immediate plans for your trip after Stockholm. I chose Ligurgfarather than Nice because (a) you mentioned it first, (b) at this time here, we try to reduce expenses to a minimum, and (t) we have some works going on in a house we have recently bought at San iiichele and I am therefore pleased when I can take advantage of anyopportunity of spending half an hour on the premises. On the other hand, there are places in the heighbourhood you have not yet seen and might enjoy seeing, that is why I thought you would ‘not have minded going there again. Please confirm your time of arrival and flight number. Otherwise, if I do not hear from you, I shall be at the Milan airport of Malpensa to meet you on flight SAS 683 due at 12.15p.m. on December 14th. We are looking forward to seeing you and Esther again. Yours sincerely, lo (L.L. Cavalli-Sforza) LLCS/at. Le + het oT pep cewel T Kee a, cake ef Laerte I te +t Roane rf \weden -
