Lionel Thomas Caswall Rolt (usually abbreviated to Tom Rolt or L.T.C. Rolt) was a prolific English writer and the biographer of major civil engineering figures including Isambard Kingdom Brunel and Thomas Telford. He is also regarded as one of the pioneers of the leisure cruising industry on Britain's inland waterways, and as an enthusiast for both vintage cars and heritage railways.
An interesting overview of the engineering progress made during the 19th century - indeed, "Nineteenth Century Engineering" might have been a more appropriate title, as there is a fair bit pre-Victoria here.
The big names and big engineering are covered, as are the less obvious (to me at least) ideas and concepts which helped Britain make such rapid progress and, for a time, lead the world.
As with all of Rolt's books, there is a campaigning undertone, but it doesn't significantly impact on the job of historian that he should have restricted himself to in such volumes.
