Célestin Port (23 May 1828 – 4 March 1901) was a French archivist and historian.
Born in Paris to a modest family (his father ran an umbrella shop), he studied at the École des chartes, composed a thesis entitled French: Essai sur le commerce maritime de Narbonne [Essay on the maritime commerce of Narbonne] (submitted in 1852) and, in 1854, became archivist of the Department of Maine-et-Loire.
Spurred on by his teacher Jules Quicherat, he dedicated forty-seven years of his life to the history of Anjou, on which he published several important works. His masterpiece — often plagiarised — is his "French: Dictionnaire historique, géographique et biographique de Maine-et-Loire" published in three volumes from 1874 to 1878. He also studied the War in the Vendée.[1]
He worked at the same time on the classification of the departmental archives and, in 1891, he donated his personal collection of archival material to the departmental archives.[1]
Célestin Port made no mystery of his militant republican sympathies, but he kept his distance from party politics. His other interests included the theatre and Latin poetry. He also amassed a collection of engravings and photographs.
