In this article, Geoff Mead illustrates the interesting overlap between old and new worlds that characterised the early nineteenth century through the story of Captain Christopher Claxton. His story exemplifies the dynamic tensions, changes and continuities of the period. His activities sometimes literally bridged old and new worlds. Yet this 'Age of Reform' also increasingly challenged his political and social perceptions. This interpretation of Claxton's long life and work in early steam navigation and in iron-bridge building illustrates well how at the cusp of technological advance changes in culture follow.
