My first and most appropriate acknowledgement is to Mrs Shirley Watson for givingme permission to edit the papers of her father, which I first examined in theInstitute of Commonwealth Studies Library (then located at 28 Russell Square) inJuly 2005. I am so grateful to Mrs Watson for her generous hospitality indiscussing her formidable father, illuminating me with family tales, beckoningmemorabilia, and rare photographs, and enlightening me on several points of herfather's career and life. As Jennings’ only survivingchild she, along with her son, Michael Watson, and daughter, Rebecca Caine, hasbeen gracious enough to provide me with the support I needed to complete thistask without ever seeking to control it.
