To mark the centenary of Richard Trevithick (1771-1833) H. W Dickinson and Arthur Titley published a fascinating book on the engineer and his work. They succeed in producing a work which appeals to the scientist, the historian and the general reader, without feeling obliged to over-simplify the technical details. Today best remembered for his early railway locomotive, Trevithick worked on a wide range of projects, including mines, mills, dredging machinery, a tunnel under the Thames, military engineering, and prospecting in South America. The book and other centenary activities helped to restore Trevithick's rather neglected reputation as a pioneering engineer of the Industrial Revolution, although his difficult personality and financial failures caused him to be overshadowed by his contemporaries such as Robert Stephenson and James Watt. The book places his achievements in their historical context, and contains many illustrations of his inventions.
