CARNEGIE INSTITUTION OF WASHINGTON DEPARTMENT OF GENETICS COLD SPRING HARBOR, LONG ISLAND, N. Y. ~ November |:, 1953 re Je Lederberg Department of Genetics University of Wisconsin Medison, Wisconsin Dear Lederberg: Rach member of the Department here has been asked to recommend someone for appointment as a new staff member, Several of us suggested Zinder during early discussions, and were told that the plan was to expand rather than inten- sify, in other words no microbial geneticists or phsgeologists. My current plan is to recommend someone who is primarily interested in how genes influence enzyme synthesis, The other requirements are age 30 - LO, demonstrated ability, and conse- cration to this objective. Whether he might want to come here, and wheat incucements we could offer, are irrelevant at this stage. Can you suggest any names? Sincerely, ADH: o1 Hershey
