Apr 12 1982 For news of Paul F Clark Thank you very much! I don't believe I'd seen him since 1958 when I left Wisconsin but I recall him with fondness and respect. I often refer to his "pioneer . . . history". And thank you for reminding me of his connection with the Institute. Certainly I will write him! But having started with such an anecdote can you leave it unfinished? Who was Paul's [. . .]? Yours Joshua Lederberg
