Y. 10021 Dear Dr. Lederberg; May I tell you how honored all of us were to have you address the Congregation. I cannot guarantee comprehension, but I can guarantee appreciation. It was most pleasant to have you with us and I hope that in the near future our paths will again cross. Would you extend Mrs. Cahn's and my pleasure to Mrs. Lederberg for giving us the privilege of having her company. I was truly sorry that your son became ill but I hope we will be able to meet him on another occasion. Again with deepest gratitude. Faithfully youry, D JUD CAHN JC:ha
