THE RALPH M. PARSONS COMPANY Facilities Operation Division M-1 A Camp Detrick Frederick, Maryland February 9, 1954 Dr. Joshua Lederberg Department of Genetics University of Wisconsin Madison 6, Wis. Dear Dr, Lederberg: I am writing to you in the hope that you will do me the favor and complete the enclosed form for the Yale Gradu= ate School, I am applying there to do my PhD. work with Dr. Bunting on Serratia phage and since the department there is practically your alma mater too, I thought that a letter from you may be of great value to me, The job here, unfortunately, carries very little original work with itself, but the remuneration is better than average, I have managed to save enough now to be able to go back for more study- ing. Donald Gordon, another worker here, wishes to be remembered to you. Many thanks in advance. Sincerely yours, tty, ©. Wa nermnan Felix E, Wassermann
