This book provides an accessible and authoritative biography of the Welsh man of science, William Robert Grove. Grove was an important and highly influential figure in Victorian science. His career as both man of science and leading barrister and judge spanned the Victorian age, and he also played a vital role in the movement to reform the Royal Society. This biography will set Grove’s career and contributions in context, paying particular attention to the important role of Welsh industrial culture in forming his scientific outlook. The place of science in culture changed radically during the course of the nineteenth century, and Grove himself played a key role in some of those transformations. Looking at his life in science can, however, do more than illuminate an individual scientific career – it can offer a way of gaining new insights into the changing face of Victorian science.
