Summary The life and works of John Mercer (1791–1866), a calico-printer from Lancashire, is a good example to illustrate the complexity of the process of printing cottons with natural colours, and the different skills required to obtain a final product able to be sold in the markets in the early years of the nineteenth century. A subtle combination of entrepreneurial dynamism, chemical knowledge, and expertise in the workshop provided a very special sort of ‘artisan-chemist’, who played a key role in (...) the industrial prosperity of the coloured textiles in the early Victorian years. The paper tries to show how, apart from the traditional ‘great luminaries’ of the period (Gay-Lussac, Berzelius, Davy, or Dalton), self-educated provincial chemists such as Mercer also made significant practical and theoretical contributions.

I take as my text today an epistle of John—John Phillips writing from Birmingham in 1839: ‘in quieter towns like … York … peace, good order, [and] leisure favour the expansion of a philosophical spirit’.

Summary During the nineteenth century French chemistry was marked by an outstanding number of Alsation chemists whose scientific contributions cannot be ignored. Especially following the Franco-Prussian War, their regional origin was given a particular importance as a means of affirming their singularity on the French scientific scene. However, some questions may be raised: can we distinguish the Alsatians from other French chemists before 1870? Were they a homogeneous group sharing a common origin? The aim of this article therefore, is, to (...) show that by their theoretical options within chemistry, their personal and professional relationships, as well as by their participation in various common initiatives, they organized themselves both formally and informally within the Parisian scientific community. Amongst these forms of organization the research school of Charles Adolphe Wurtz (1817?84) emerges as the nucleus of what we may envisage as a network of Alsatian chemists working in Paris, in the second half of the nineteenth century.
