Theodorus Marinus Roest

Theodorus Marinus Roest (14 April 1832, Dongen – 2 September 1898 Baden-Baden) was a Dutch numismatist and conservator of the numismatic collection of the Teylers Museum.

Through the efforts of the archivist of the city of Haarlem Adriaan Justus Enschedé, Roest was hired to catalog the collection of the Teylers Museum.

In 1886 Roest was named conservator, and in 1889 he published his "Catalogue du cabinet numismatique de la Fondation Teyler à Harlem".

In 1893 he published the work "De munten van het Graafschap en Hertogdom GELRE" (Coins of Gelre, or the Gelderse Mint), and later he left his collection of Gelderse coins to the museum.

In 1892 Roest was the founder and first chairman of the coin society Koninklijk Nederlands Genootschap voor Munt- en Penningkunde.
