Precursors of the modern chemical industry began to emerge in Northern Europe in the middle of the eighteenth century. The Industrial Revolution boosted activities such as soap-making, glassmaking and textiles production, which required increasing quantities of chemical products. The Lead Chamber process for the manufacture of sulphuric acid, required for the production of dye, was developed in the 1740s by John Roebuck then based in Birmingham. Production of this key commodity rose steadily. By the 1820s, British annual production had reached 10 000 tons of 100% acid. By 1900, Britain was producing one quarter of the world's output with an annual production approaching one million tons. Demand for alkalis for glassmaking and soap-making, for textile dyes and for bleach was also growing rapidly in the second half of the eighteenth century, and it became clear that existing sources of these materials would not be sufficient. In response to a prize established by the Academie des Sciences, Nicholas Leblanc had devised by 1791 a method for converting common salt into soda ash, which was to become the central operation of the world alkali industry for about one hundred years.

The key aim of this volume is to demonstrate ways in which an understanding of history can be used to inform present-day transport and mobility policies. This is not to say that history repeats itself, or that every contemporary transport dilemma has an historical counterpart: rather, the contributors to this book argue that in many contexts of transport planning a better understanding of the context and consequences of past decisions and processes could lead to more effective policy decisions. Collectively the authors explore the ways in which the methods and approaches of historical research may be applied to contemporary transport and policy issues across a wide range of transport modes and contexts. By linking two bodies of academic research that for the most part remain separate this volume helps to inform current transport and mobility policies and to stimulate innovative new research that links studies of both past and present mobilities.

For the majority of us the opportunity to travel has never been greater, yet differences in mobility highlight inequalities that have wider social implications. Exploring how and why attitudes towards movement have evolved across generations, the case studies in this essay collection range from medieval to modern times and cover several continents.

This title was first published in 2003. Suburbanizing the Masses examines how collective forms of transport have contributed to the spatial and social evolution of towns and cities in various countries since the mid nineteenth century. Divided into two sections, the volume develops first the classic tradition on transport and the city, public transport's 'impact' on urban development. The contextualisation of transport is one important factor in the historical debates surrounding urban development. As well as analysing the discourse employed by urban political and business elites in favour of public transport, these contributions show the degree to which practice often fell short of ideals. The second section tackles the professional paradigms of urban transport: the circulation of traffic in cities and the technological modes appropriate to its realization. In particular these contributions explore the paradigms held by professional planners and managers, and the political classes associated with them. From a variety of perspectives Suburbanizing the Masses demonstrates the continuing relevance of socio-historical inquiry on the relationship between public transport and urban development. By differentiating between the many roles of urban transport in the nineteenth century, it confirms that public transport was not directly linked to urban growth, and instead often had only a limited effect on the wider urban structure. Suburbanizing the Masses forces a reassessment of the received historiography that maintains cheap public transport was essential to the spectacular growth of cites in the nineteenth century.
