LOUIS 830, MISSOURI —€ DEPARTMENT OF ZOOLOGY June ll, 1963 Dr. Joshua Lederberg Department of Genetics Stanford University Medical School Palo Alto, California Dear Dr. Lederberg: First of all, I wish to tell you how much I enjoyed the opportunity of meeting with you and discussing problems related to the nervous system. Iam at present in the process of writing an article for Science on our work and I should like to quote the short essay you kindly gave me on Eugenics and Euphenics. In the pamphlet it is mentioned that the essay represents the “substance of a contribution to the Ciba Foundation Symposium, November, 1962, abbreviated for submission to Nature. " I wonder if it is at present already in print in Nature and if you have any other article on this ¥ matter which I could read. Under separate cover I am sending you some of our recent work dealing with the Nerve Growth Factor. Most cordial greetings. put d/v_ nap) -lAe7 Sincerely, Difz fer: ‘- Ty cufstem , Rita Levi-Montalcini RLM: 1ti 5 Yoo 4 > Encleorh ArneMoom, \N ud, Aven Ke Ae ne Popes A bs pote y . ”
