WN NOV THE UNIVERSITY OF TENNESSEE MEMORIAL RESEARCH CENTER KNOXVILLE October 30, 1962 Dr. Joshua Lederberg Professor of Genetics Stanford University Medical Center Palo Alto, California Dear Dr. Lederberg: Thank you for your letter of October 24th. I found your reprint most interesting and knowing you and your work did not find it unexpected though I had not been aware of it. Dr. Beadle at almost the same time had suggested the possibility in neoplasia of enzyme deletion playing a not un- like role in the genesis of tumors. Your having made the suggestion in your nutritional concept which our work seems to fit, I thought you might be interested in the enclosed reprints. Most of our work relating to the papilloma virus is currently in press in The Journal of Experimental Medicine. With best regards. Sincerely yours, a“ Ae be “Stanfield Rogers Enclosure SR:srh SEP ~ 6 1982 1 1962 pj ature SAO boy
