THE UNIVERSITY OF CHICAGO CHICAGO 37: ILLINOIS INSTITUTE OF RADIOBIOLOGY AND BIOPHYSICS 6200 Drexel Avenue August 10, 1950 Dr. Joshua Lederberg Department of Bacteriology University of California Berkeley, California Dear Josh, Forgive me for being so late in replying. I haven't yet been able to dig up anything for Ellis, I agree with you that it would be very regretable to lose Ellis. I will continue looking, though I wish the hell that there was something I could do right away. We had heard from the Blair's of your visit to Monterey. They enjoyed meeting you. Jane and I are off to New York for a week and then I will spend a few days at Cold Spring Harbor, arriving back in Chicago on July 26th, Sorry to hear about your camera difficulties, and feel that I am responsible either for not having given you sufficient instructions or for recommending a poor instrument, Except that it is not quite true, I will not say that we don't wish to be in California right now, Regards to Esther. Sincerely, Aaron Novick AN/sds
