a + Seamenrt ISTITUTO SUPERIORE DI SANITA ROMA VIALE REGINA ELENA, 299 Prof. J.Lederberg Department of Genetics The University of Wisconsin Madison, Wis. U.S.A. Dear Lederberg, I have made the application for a Fulbright Travel Grant, and I hope to be able to cross the Ocean and meet you somewhere in the new World this Summer. I have applied on the basis of a letter by Bonner inviting me for a period of three months and guaranteing me a support of 1,000 dollars. I confess that I am no longer very sure that I made the best choice. Biochemistry of Neurospo- ra is of course a wonderful field, but Genetics of Streptomyces is very much more actractive to me, After the first success the progress in this field has been vety laborious, the quantitative reproduci-~ bility of the results was low, and I have been some- what distracted from th¢s topic. I realize that, to overcome this lag phase, it would be necessary for me to devote all my energies to this field, which now occupies only 20 per cent of my time. A short period of collaborative wark with Bradley would be, as far I can see, the best start, and a longer period could perhaps bring us to some consistent achievement. _ TI must confess I have no idea how I could manage to join Bradley fora longer period than a week. I could pospone my return from the U.S.A., and spend a few months with Bradley, but how could I justify this program to Bonner? Moréover I cannot stay in the U.S.A. without an adeguate support, and Bradley has not significent funds available. A possible arranvement would be to have Bradley in my laboratory. But I am afraid that, unless he gets a grant from the U.S., I won't be able to find any financial support for him. This last solution would allow my wife also collaborate with Bradley. ISTITUTO SUPERIORE DI SANITA ROMA VIALE REGINA ELENA, 299 I would be grateful if you could suggest a way in which I might join Bradley. I trust that sooner or later this will be possible and, at least, I hope to profit from my coming subjourn in the U.S. to make some arrangement for the future. With my best regards to you and Mrs Lederberg from my wife and myself. Sincerely yours Gye Set (G.Sermonti) Rome, February 6th, 1958.
