This thesis examines the work of the nineteenth-century Stevenson civil engineering firm to argue
that civil engineering should be approached geographically both because it takes place in and is
shaped by particular spaces, but also because the result of such work reshapes space and the
relationship between places. Geographers have extensively analysed the ways in which humans
have worked to alter environments, but relatively little attention has been paid to engineering as a
socially and geographically transformative process, to the technical questions and to the engineering
professionals whose work brought about such change. This thesis analyses engineers as social and
technical agents of environmental change, rather than viewing their role as the simple
implementation of directives developed elsewhere and by others. It combines insights from the
history and historical geography of science, environmental history and the history of technology to
make a case for the relevance of an historical geography of engineering.
The thesis explores these issues through the work of the Stevenson family. The Stevensons
were an Edinburgh-based and internationally-renowned firm of engineers who specialised in the
construction of coastal infrastructure. The start and end dates of the thesis indicate, broadly, the
careers of David and Thomas Stevenson, who jointly managed the family firm under the name D. &
T. Stevenson between 1850 and 1886. The empirical basis for this thesis draws upon the detailed
analysis of the firm’s archival records: technical publications, project reports, diaries,
correspondence, maps, plans and diagrams.
The work of the Stevensons—their engineering epistemologies, practices, and professional
identities— are examined through four diverse projects undertaken by the firm in the nineteenth
century. These projects are: the training of new engineers; surveying and designing improvement
works for the rivers Tay and Clyde; the implementation of a coastal sound-based fog signal network;
and the failed attempt to expand Wick harbour through the construction of a breakwater. These
projects highlight the range of activities undertaken by nineteenth-century engineers and illustrate
the ‘making’ of engineers and the work they did by highlighting training and learning, surveying,
maintenance, testing, evaluation, repair and the explanation of failure. With reference to these
projects and by drawing upon relevant contextual material, the thesis examines the
conceptualisation of geographical space and natural forces in engineering, the relationship between
science and engineering, the nature of expertise and notions of engineering judgement, and the role
of family, legacy and reputation in securing professional credibility and status.
This approach challenges older historiographical traditions which portrayed engineers as
individual geniuses. The thesis instead understands engineering to be a combination of specialist
knowledge and tacit skill and situates engineers within their social and institutional networks of
power and authority. In pointing out that some engineering works failed, the thesis challenges the
tendency in histories of engineering works to focus on success. It makes the case for an historical
geography of engineering as a way of understanding engineering as an activity, a status and as
processes which changed human-environment relations
