Telephone : Cambridge 48011 MEDICAL RESEARCH COUNCIL SEP 18 1964 LABORATORY OF MOLECULAR BIOLOGY, HILLS ROAD, CAMBRIDGE. 16th September, 1964. Professor J. Lederberg, Dept. of Genetics, Stanford University, Palo Alto, California, U.S.A. Dear Josh, I am writing to ask whether you might be interested in employing my technician for a year. I am going to spend five months in Berkeley next year and my technician wants to take off the whole year to work somewhere in the States. Her name is Muriel Wigby and I can strongly recommend her as being conscientious and reliable. She has been trained in most techniques of microbial and phage genetics and she has also had some biochemical experience as well. She also learns very quickly indeed and if you have a large program involving UNIVERSITY POSTGRADUATE MEDICAL SCHOOL, yan d 6 routine isolation of mutants, mapping, etc. she might be extremely useful. If you are interested could you please let me know. have also written a similar letter to Charlie Yanofsky whom you might get in touch with. 2 Yours, S. Brenner
