The editors invited selected authors who had participated in or observed developments in biochemistry and molecular biology, particularly in the second half of this century, to record their personal recollections of the times and circumstances in which they worked. Having been given free reign, both content and style of the contruibutions reflect the flavour of the personality of the author. The book reflects the explosive development of biochemistry and molecular biology and related sciences that had led to the almost unique situation of these fields coming of age at a time when their founding fathers, or their scientific children, were alive and well. The contributions in this volume encompass a wide variety of experiences in many different countries and in very different fields of biochemistry.
