WASHINGTON UNIVERSITY SCHOOL OF MEDICINE SAINT LOUIS DEPARTMENT OF MICROBIOLOGY EUCLID AVENUE AND KINGSHIGHWAY October 31, 1958. Dr. Joshua Lederberg Department of Genetics University of Wisconsin Madison, Wisconsin Dear Joshua: We are all excited and delighted with the prize. It involves an additional trip this fall which I am afraid you will have to put up with, but then this has not been an ordinary year and you have lots of time to recover in pleasant sur- roundings. If it is still possible for you to cope with ordinary business, I would like to ask you if you would take on the re- sponsibility for ordering office equipment that you think is best. It is obvious that you have lots more experience with these various gadgets. Perhaps we can share them to begin with, but if the load becomes excessive we will duplicate the items. It is apparent that some large items which might be awkward for a small group to have could profitably serve our combined groups. I will ask Mel to write you separately about the micromanipulator, Please give Esther our additional congratulations and warmest wishes, . Sincerely, (then AK/McK Arthur Kornberg.
