September 26, 1952 Dear Sol: I have your note re Trefferdd project. I don't envy you the assignment of sitting in judgnent on your colleagues' work and capabilities. Unfor tunetely, I am not well informed about Treffers' work. We had some correspondence nearly a year ago, but I received very few details from hia. If I say that I aimply have no opinion on the matter, I mean just that and please do not construe it negatively in any way. Sorry not to be more helpful, Sincerely, Joshua Lederberg
