Ruben and Sholto Percy were London based urban historians active in the early 19th century. The Percys were ostensibly monks of the Benedictine Monastery of Mount Benger, however these identities were in fact pseudonyms for Joseph Clinton Robertson (1788 – September 22, 1952) and Thomas Byerley (1788 - 1824), respectively. The name "Percy" was derived from the Percy Coffee House of Rathbone Place, London, where Byerley and Robertson frequently met to discuss their work. The Percy's are best known for their collective works entitled, "The Percy Anecdotes", a multivolume compilation of pirated stories. They also began work on an anecdotal history of Europe's major capitals, though the work, stymied by Byerley's death in 1824, never got beyond London.
