[5] On 1 April 1680, Dockwra established the first penny post, which served London and the surrounding area to a distance of ten miles.
[6] The service worked on the basis that the one penny postage was paid when the letter was accepted (a key element of Rowland Hill's 1839 reforms of the British postal system).
Dockwra obtained a patent for his service, but unfortunately for him the profits from the government-operated General Post Office had been granted to the King's brother the Duke of York.
He was dismissed in 1700, however, after an investigation into his conduct of the business, including complaints that he had moved the central office from Cornhill to a less convenient location and had opened and detained correspondence.
This project introduced some technical innovations and helped to reduce England's dependence on imports, but it was not a financial success for Dockwra, who lost control of the business.
