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.
