FOR INTER-DEPARTMENTAL USE STANFORD UNIVERSITY OFFICE OF 27 April 1959 m ” Tos Dr, Joshua Lederberg Department of Biophysics Re: “estex Committee on Planetary Biology Dear Dr. Lederberg: I think it will be best if I resign from the Westex committee, The subjects under discussion are far removed from my major interests in geochem- istry, and I haven't felt that I could make any significant contribution to the committee's work, I had hoped to find time to build up a background in planetary geology, but time for such extracurricular activity is just not available. I have so many irons in the fire right now that I am not doing justice to any of them, and I think my best move is to get out from under those projects where i am contributing least. This resignation is submitted with considerable reluctance, because I have found the discussions of your committee most interesting and the members very congenial, But so far the benefit has all been to me rather than to the committee, and I hardly feel that I can continue to ask NASA to finance my education in planctary biology. If the committee needs geochemical (or astro-=- chemical) advice, I am sure that Dr. Urey is in a much better position to help you than I am. Thank you for giving me the chance to serve on the committee, Sincerely yours, food ff Konrad B, trauskopf »{ ‘DM Gd oASHOES
