This chapter addresses the question: How did the term become familiar in society? Even the earliest uses demonstrate the integration of knowledge classification and engagement with large audiences. Derived from German usage, the term ‘applied sciences’ was coined early in the nineteenth century by the poet Samuel Taylor Coleridge. It was key to underpinning a major new encyclopaedia project intended to structure knowledge and thinking. A succession of loyal editors realised his vision as the massive Encyclopaedia Metropolitana, advertised using Coleridge’s coinage. It would also be taken up by King’s College London seeking to describe its course teaching knowledge underlying engineering without claiming to be technical training. Meanwhile, the chemist J. F. W. Johnston used the term to promote the services he offered farmers. During and after debates over Corn Law Repeal, the press discussed Johnston’s applied science as a potential saviour of agriculture. The term’s use then snowballed.
