This is the first complete edition of Boyle’s correspondence. More than a third of the letters presented here have never previously been published. It is fully annotated, with an introduction and comprehensive general index. The Correspondence of Robert Boyle is a British Academy Research Project. Robert Boyle (1627–91) was not only one of the founders of modern Western science but also a key figure in late 17th-century English culture. Himself a prolific and innovative experimenter, he was at the centre of a network of figures with similar interests. These included some of the most important European intellectuals of his day, together with many leading figures in the most innovative and influential scientific institution of the seventeenth century, the Royal Society.
