FEBL CLEVELAND CLINIC 8 1963 2020 EAST 9382 STREET CLEVELAND 6, OHIO RESEARCH DIVISION February 12, 1963 Dr. Joshua Lederberg Director, Joseph P. Kennedy, Jr. Laboratories for Molecular Medicine Stanford University School of Medicine Palo Alto, California Dear Doctor Lederberg: I am puzzled by your memo. It doesn't look like three other guys to me, but from what Mark Parker wrote to me, he wanted the negative destroyed. Whatever that may mean, I hope we haven't done you wrong. I liked your Molecular Biology, Eugenics and Euthenics immensely. If you have got any other similar efforts, do let me know. You write with such clarity even I can understand it and that takes a bit of doing. With warm personal regards, 3 Cordially yours, Dor NO pe Irvine H.
