Birmingham’s Lunar Society was the perfect setting for a number of important joint ventures involving several of the greatest pioneers of modern capitalism, such as M. Boulton, J. Wedgwood, and men of science like J. Watt, J. Priestley and E. Darwin. R.E. Schofield’s (1963) and A. Musson’s (1969) classic studies underlined the relationship between this group of intellectuals and the Industrial Revolution, paying particular attention to the relation between scientific research, technical innovation and economic development. More recent research by R. Porter (1980) and P. Jones (2008) has gone some way to placing the Society within the general framework of provincial industrial illuminism. This paper aims to reexamine the lively debate between the perspicacious members of the Lunar Society and London’s scientific, political and economic world. In particular, it provides interesting food for thought on how the lunarticks actually promoted interests linked to local development, both in terms of scientific communication and political relations and how they saw London as a competitive place, the scene of social legalization and the raising of scientific prestige. Clear indications of the relationship between the Lunar men, the London establishment and the other institutions of the realm can be seen, for example, from events regarding the political debate over Watt’s request for a patent renewal for his separate condenser, with a resulting decisive effect on research into the steam engine and its use in industry. In turn, Wedgewood saw London as an important showcase to promote his wares. The quest for a wider market for his goods pushed him to the experimentation of new models, materials and production methods. His technical expertise and fruitful association with Watt and Priestley gave rise to the "pyrometer" and acknowledgement by the Royal Society. The Birmingham society engaged in lively exchanges with the capital’s scientific associations, particularly with the Society for the encouragement of arts and the Royal Society, of which nearly all the Birmingham members became fellows. The Lunar Society members presented numerous political proposals and petitions to Parliament for the modernization of their local working area. Consequently, London became the political and cultural interlocutor for a group of rising provincial bourgeois, whose scientific curiosity and dedication to experimentation were to drastically change the history of modern England.
