"Britain and France were the leading industrial nations in eighteenth-century Europe. This book examines the rivalry which existed between the two nations and the methods used by France to obtain the skilled manpower and technology which had given Britain the edge - particularly in the new coal-based technologies. Despite the British Act of 1719 which outlawed industrial espionage and technology transfer, France continued to bring key industrial workers from Britain and to acquire British machinery and production methods." "Drawing on a mass of unpublished archival material, this book investigates the nature and application of British laws and the involvement of some major British industrialists in these issues, and discusses the extent to which French espionage had any real success."--Jacket.
