December 26, 1974 Dr. Gunther St Department of Molecular Biology University of California Berkeley, California 94720 Dear Gunther, Calvin Ward told me the other day that he had once had a lecture or seminar from you concerning theoretical predictions about the maximum possible rate of growth of bacteria. If you can give me any detail or references on this subject, I would apprectate it very much. Besides the theoretical side of this question I am also interested in finding empirical studies on maximm achievable growth rates. Some of the numbers that are recorded in the literature are incredible and in fact probably false but I would be interested to know what your own perspective on that is. I believe I heard that Vielmetter may have done some work that bears on this question. Yours with best wishes, JL/rr
