Bust of Esprit Requien in Avignon

From the age of 18, he was associated with the botanical garden in the city of Avignon. He performed extensive studies of flora native to Corsica and in the environs of Mont Ventoux. During his lifetime, he amassed an herbarium of 300,000 specimens.[1]

In the fields of conchology and palaeontology, he conducted collecting expeditions to the Pyrenees, Catalonia and Italy. The natural history museum, Musée Requien, in Avignon is named in his honor.[2]

He is the taxonomic authority of a monotypic plant genus Helxine, now treated as a synonym of Soleirolia soleirolii, in the nettle family Urticaceae.[3] The genera of lichenized fungi, Requienella (author Jean-Henri Fabre) and the flowering plant Requienia (author Augustin Pyramus de Candolle) are named after him,[4] as are plants with the specific and subspecific epithets of requienii.[5][6]

The World Register of Marine Species lists 57 marine species names by Requien, most of which have become synonyms.[7]
