ABSTRACT
This review article is based on the Lonsdale Lecture and Teaching Plenary that was presented by the author under the auspices of the Biological Structures Group of the British Crystallographic Association (BCA) at its Annual Conference held at Keele University in April 2011. This event was chaired by the BCA President, Professor Elspeth Garman. This article is divided into two parts. Part 1 is a short review of the previous Lonsdale Lecturers and also a glimpse of the tributes made to Kathleen Lonsdale’s achievements as well as a short description of her broad interests spanning not only crystallographic science but also her pacism. Part 2 is my review of synchrotron radiation (SR) and crystallography involving the perspectives that I gained, and their allied topics, at the Synchrotron Radiation Source (SRS) and European Synchrotron Radiation Facility (ESRF), the rst dedicated SR X-ray source and the rst third-generation low-emittance SR source, respectively.
