James ChalmersBack to Innovators

James Chalmers was a bookseller, printer and newspaper publisher on Castle Street in Dundee who went on to become a Burgh Councillor and served as Convener of the Nine Incorporated Trades. From the mid 1820s he began to campaign for improvements to the speed of the postal service between Edinburgh and London and, from 1834, he promoted the idea of an adhesive stamp which could then be cancelled when used. The Penny Post, introduced in 1840 and proposed by Rowland Hill introduced a single rate of postage alongside the world's first adhesive stamp, the Penny Black.
