AMERICAN PHILOSOPHICAL SOCIE Philadelphia, Pennsylvania 191% ny D NOV13 d EXECUTIVE OFFICE: NOV. 1979 104 South Fifth Street Phone: (215) MA 7-0706 Op, wes November 13, 1979 Dr. Joshua Lederberg Rockefeller University New York, N.Y. 10021 Dear Dr. Lederberg: ot. Your letter of birthday congratulations —_—_— to Dr. Corner arrived on Friday, in ample time for me to read it (I hope that you, he and the Postal Service will not mind my reading his mail) at the general business meeting. The night be- fore we had had at the dinner an informal pre- sentation to Dr. Corner, which was attended by his son and grandsons. It was an agreeable oc- ecasion, at which Dr. Corner himself spoke well, warmly, and strongly. I know that he appreciated your thoughtful remembrance of him, and am sure that you will be hearing from him personally. We look forward to seeing you here in Philadelphia at some meeting of the Society in the near future. Very Aaithfully yours, Executivé Officer and Librarian
