Lederberg, Department of Genetics, Stanford University, Medical Center, PALO ALTO. CALIFORNIA, U.S.A. Dear Joshua, As you probably know, or could guess from my age, I retire at the end of this year and active moves are on foot to find my successor, I have no formal say in the appointment but I have authority from our Vice-Chancellor to obtain what advice I can from my friends, Personally, lam keen that Gus. Nossal should get the job and, if you agree that he is a good man for it, I should be most grateful if you could let me have something in a letter that I could pass on to the committee concerned. Quite apart from anything directly to do with his scientific status, any impressions in regard to his competence in administrative matters, or his acceptability in the American scientific environment, could be helpful. I thought of your exobiological activities when I went out to Grumman Aviation last May and climbed into the Lunar Excursion Module mock-up. It made the business seem almost real! Best wishes to you both, Yours sincerely, free F. MO Barnet Director Address: C/o ROYAL MELBOURNE HOSPITAL POST OFFICE, VICTORIA, AUSTRALIA. TELEPHONE: 349177
