provides scholarly yet accessibly written books on Welsh scientists who have made a major and significant contribution to scientific developments and innovation. Historically, there has been a tendency to confine the perception of Welsh culture to that encompassed by its writers, its poets, its musicians and its theologians; this series redresses that perception and demonstrates the very significant contribution of its scientists on a global scale. Titles are biographical, written by authorities on their subjects in a way that is lively and accessible, looking at the people behind the science. The scientific content is explained clearly in a way that is within the reach of readers with little or no knowledge of science.
