UNIVERSITY OF PITTSBURGH SCHOOL OF MEDICINE PITTSBURGH 13, PENNSYLVANIA DEPARTMENT OF MICROBIOLOGY September 27, 1960 Dr. Joshua Lederberg Department of Genetics Stanford University Palo Alto, California Dear Josh: When I saw Lou Baron in Boston (where we were both stranded by the hurricane), he told me that you would like David Coahran to stop in Palo Alto even though he had decided that he was committed to go to Washington this Fall. I called him the day before he left and asked him to stop on his way out and to write you in any case. He said he would write but that he didn't think he could stop on his way out. I presume he has done one or the other by this time. I tried to convince him of the importance of this opportunity but I'm afraid it was a few months too late. I can think of no other qualified people. Best of luck on the project. It was very enjoyable becoming acquainted with you and Esther at Bar Harbor. | Sincerely, Charles C. Brinton, Jr. Assistait Research Professor of Microbiology CCB/gmv
