In Britain, the name of Cadbury has been synonymous with chocolate ever since John Cadbury opened his factory in 1831. This book, written by Richard Cadbury (1835–99) under the pen name 'Historicus', was published in 1892. It describes the natural history of the tropical American cocoa plant, its spread in cultivation across the world, and the history of its use. He also deals with the manufacturing process, as exemplified by the Cadbury factory at Bournville, surrounded by the model housing and leisure facilities which the family built for its workers. The processing of cocoa beans into solid and drinking chocolate is described in detail, with emphasis on the developments in machinery which simplified production. A chapter deals with the importance of the vanilla plant for flavouring, and an appendix gives guidance on the cultivation of cocoa trees. This remains a fascinating account of one of the world's most popular indulgences.
