(she - i THE WHITE HOUSE WASHINGTON August 31, 1961 Dear Dr. Lederberg: Thank you for your letter of August 28th. The major emphasis of the panel to be chaired by Dr. Beeson will relate to man in space. At the first meeting of the panel which is scheduled for 12 September at the School of Aerospace Medicine, I intend to raise the question as to whether the panel will concern itself with exobiology. I will write you after the meeting. Sincerely, Jafpes B. Hartgering, M.D. Dr. Joshua Lef€rberg Genetics Department School of Medicine Stanford Umiversity Palo Alto, California
