'One of the tests of success of a volume such as this ... is to consider how well the character and personality of the subject shines through the work. As far as I am concerned this book passes the test with flying colours. This is a splendid tribute to a very great man and should be of interest not only to students of crystallography in its myriad applications, but also to historians of science.'Professor C.A. Taylor, University of Wales, Contemporary Physics, 1993, volume 34, number 3
