Paul Barthélemy Mirabaud (29 June 1848[1] – 12 May 1908)[2] was a French banker and philatelist from Versailles, Yvelines who was a specialist in the stamps of Switzerland.
In 1921, he was one of the "Fathers of Philately" entered on the Roll of Distinguished Philatelists. Together with Swedish-born Baron Axel de Reuterskiöld he wrote Les Timbres Postes de la Suisse 1843-1860 which was published in 1899. The book is considered well-researched and the first published deep study of Swiss philately. The book is still considered a standard reference and has been the basis for many more modern or more particular enquiries into the field of the Swiss classical issues.
