May 8, 1948 Dear Dr. Lederberg, I wonder if you would be kind enough to serve on a committee to help Dr. Irwin choose the papers for the Invitational Program of the Genetics Society at the Washington meeting. It should not take much time. Dr. Irwin will get in touch with you regarding the work to be done. Please let me know whether you will accept this assignment. Sincerely Laurence Snyder President, Genetics Soc. America
