William and Lawrence Bragg, Father and Son

In 1912 Lawrence Bragg explained the interaction of X-rays with crystals, and he and his father (William) thereby pioneered X-ray spectroscopy and X-ray crystallography. They then led the latter field internationally for 50 years, when most areas of science were transformed by the knowledge created: physics, chemistry, geology, materials science, electronics, and most recently biology and medical science. This book charts how this humble pair (William English, hisson Australian) rose from obscurity to international prominence and then back to current, undeserved obscurity. Attention is also given to the crucial roles of both father and son during the dreadful years of the First World War, and to William's early and unshakeable belief in the dual wave andparticle natures of radiation and his eventual vindication.Unlike earlier studies, the book highlights the intimate interactions between father and son that made their project possible, emphasizes personal, family, and wider human relationships, and offers new insights into teaching and research in a British colonial setting.

It superbly rewards one's attention., It superbly rewards one's attention. [A] valuable and thoughtful book., 'Jenkin's masterly exposition [...] an admirable book.' Physics World, July 2008, the level of detail especially about their personal lives shows the considerable time and effort the author took in putting together this interesting and well-written book. The book would certainly appeal to any reader interested in the history or science or the research work of William and Lawrence Bragg. The personal accounts set the book apart and give the reader a feel for who William and Lawrence were and the journeys they underwent., A valuable and thoughtful book...I highly recommend Jenkin's biography to all readers interested in the history of 20th century physics and to those interested in the history of condensed matter physics or crystallography.

Dr John JenkinHonorary Associate, Philosophy Program, La Trobe University, AustraliaJohn Jenkin was born, raised, and educated in Adelaide, South Australia, and graduated B.Sc. with first-class honours in physics from the University of Adelaide in 1960. He then completed a Ph.D. in low-energy nuclear physics at the Australian National University in Canberra, and held post-doctoral appointments at the Atomic Energy Research Establishment, Harwell, England, and the University of Minnesota, USA. The remainder of his career has been spent at La Trobe University in Melbourne,Australia, where he became Reader and Head of the Department of Physics (1968-1992), and then joined the history-and-philosophy-of-science program in the Faculty of Humanities and Social Sciences (1993-1999). His research at La Trobe has concerned the electronic properties of materials (in Physics) andthe history of the physical sciences in Australia (in Humanities). He retired in 2000 and is currently a Research Associate in the Philosophy Program at La Trobe.
