L. Bragg 226 Dame Kathleen Lonsdale* Others have written about Dame Kathleen Lonsdale's scientific achievements; I wish to add a tribute to her as a person. She was one of the most thorough, high- principled, and courageous people I have known. We who work in the field of X-ray analysis cannot be too grateful for all she did to help us. Her early collabora- tion with Astbury in preparing an exhaustive survey of space groups was typical. The set of formulae for structure analysts, and the work on International Tables for the Union, were models of accuracy and ordered arrangement. No trouble was too great for her, and it was all done disinterestedly for the general good, much of it behind the scenes and in helping others. I was in correspondence with her shortly before her death when she was trying to complete two books * This appreciation of Dame Kathleen, who died on 1 April 1971, was one of the last things that Sir Lawrence wrote for publication. It seems appropriate to print it
