Quote from Wikipedia: > The law was named in 1860 by Henry Dunning Macleod, after Sir Thomas Gresham (1519–1579), who was an English financier during the Tudor dynasty. However, there are numerous predecessors. The law had been stated earlier by Nicolaus Copernicus; for this reason, it is occasionally known as the Gresham–Copernicus law.[3] It was also stated in the 14th century, by Nicole Oresme c. 1350,[4] in his treatise On the Origin, Nature, Law, and Alterations of Money,[5] and by jurist and historian Al-Maqrizi (1364–1442) in the Mamluk Empire;[6] and noted by Aristophanes in his play The Frogs, which dates from around the end of the 5th century BC.
