UNIVERSITY OF CALIFORNIA, BERKELEY BERKELEY * DAVIS * IRVINE * LOS ANGELES * RIVERSIDE * SAN DIEGO * SAN FRANCISCO SANTA BARBARA * SANTA CRUZ DEPARTMENT OF BIOCHEMISTRY BERKELEY, CALIFORNIA 94720 February 22, 1971 Dr. Joshua Lederberg Genetics Department Stanford University Palo Alto, California Dear Josh, I have been asked to arrange a session on chemical and biological warfare at the annual meeting of the American Society of Biological Chemists in San Francisco during the week June 13-18, The other evening I heard your lecture on the Stanford campus radio Station and I conclude that this presentation would be of general interest to members of the society. Our program would be at 8 PM and probably on Wednesday, June 16. Besides yourself there would be one other speaker who would, I expect, deal with some aspect of the tear gas-herbicide situation in SE Asia. Hoping that you can join us, Sincerely, Jo. 6. Nettands Tn, JBN/nb JUL 20 197; I am sorry this was shoved aside, so you had the discourtesy of a non-reply. But as you may have gathered, I was out of town at the time anyhow. Contritely, ( ‘SIP Sane 7) >)
