Crystal Clear takes you behind the scenes in the life of one of the most prominent scientists of the twentieth century, William Lawrence Bragg (WLB) - an innovative genius, who together with his father, William Henry Bragg (WHB) founded and developed a whole new branch of science, X-rayCrystallography. The main body of the text contains the hitherto unpublished autobiographies of both WLB and his wife, Alice. Alice Bragg was a public figure in her own right. She was Mayor of Cambridge and National Chairman of the Marriage Guidance Council among other roles. She and WLB were asdifferent as chalk and cheese. Their autobiographies complement each other to give a rounded picture of the real personalities behind their public appearance. They write of their travels, their family life, their friends and their joys and sorrows. They write most of all about each other.Their younger daughter, Patience Thomson, provides anecdotes and vignettes, bringing her parents to life. She has also included extracts from previously unpublished letters and from articles which Alice Bragg wrote for National newspapers. The result is an unusual insight into the lives of twodistinguished people. The two accounts reveal a fascinating interaction between these two characters, neither of whom could have achieved on this scale without the other. There is an underlying love story here which humanises and transforms. This is a unique book, adopting an original viewpoint,which will take the reader far beyond the scope of a normal biography.
