THE ROCKEFELLER INSTITUTE NEW YORK 21,NEW YORK October 2, 1961 Dr. Joshua Lederberg Department of Genetics School of Medicine Stanford University Palo Alto, California Dear Dr. Lederberg: I am planning to attend the meeting of the National Academy of Sciences in Los Angeles the latter part of October and to be in the San Francisco area around the 4th or 5th of November. I would like very much to come down to Palo Alto to see you, because there are several questions pertaining to the colicines I would like to dis- cuss with you. Will you be there at that time and if so would it be convenient if I were to drop in for an hour or two of discussion. I can telephone you from San Francisco to find out what day and hour would be conveneint for you. Very sincerely yours, Walther F. Goebe WFG: bh 4, Oda ons gprk buMhe hee 5 phare <3 gore!
