Penny post man – Aberdeen Press and Journal 28 January 1799:
On Saturday last died here, Mr Peter Williamson, well known for his various adventures through life.
He was kidnapped when a boy at Aberdeen, and sent to America, for which he afterwards recovered damages.
He passed a considerable time among the Cherokees, and on his return to Edinburgh amused the public with a description of their manners and customs, and his adventures among them, assuming the dress of one of their Chiefs, imitating the war-whoop, &c.
He had the merit of first instituting a penny-post in Edinburgh, for which, when it was assumed by the Government, he received a pension.
He also was the first who published a directory, so essentially useful in a large city.
