In August 1812 Henry Bell s Comet, a revolutionary paddle steamer, made her first journey on the Clyde. This marked the start of extraordinary developments that completely transformed shipping and transport in Britain, Europe and the Americas. The paddle steamer soon became the key link with Empire, pushing the Honourable East India Company s wooden walls off the seas; it provided the all- important link with the Americas, and it offered emigrants to the New World a means of pushing westwards. In this fascinating new book Nick Robins analyses the remarkable impact of the paddle steamer and goes on to describe its development, both in terms of technology design and in relation to its effects on the transformation of nineteenth-century economies.
