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.
A British historian of the industrial age and a waterway enthusiast, recounts the history and present-day condition and operation of France’s premier waterway. The book first presents the genius of the concept and the construction, and then recounts the author’s voyage around 1970 along the waterway. The extended travelogue at the end of the book, in which the author traverses the entire canal including inspecting nearly every engineering structure of significance—the locks, weirs, aqueducts, intake structures, even a tunnel—might be tedious for some, but there is much to hold interest for those who have traversed the waterway, especially when the author’s comments jibe (or not) with one’s own observations.
