The Bibliothèque Marmottan (French pronunciation: [biblijɔtɛk maʁmɔtɑ̃]), located in the Parisian suburb of Boulogne-Billancourt, is a public library bequeathed in 1932 to the Académie des Beaux-Arts by its founder Paul Marmottan.
Dedicated to the First French Empire and open to readers interested in this period, it contains some 25,000 books and periodicals, making it one of the largest Napoleonic libraries in the world.
Paul Marmottan (French pronunciation: [pɔl maʁmɔtɑ̃]; 26 August 1856 – 15 March 1932) was a French art historian, collector and patron. Both through his taste and his writings, he was a precursor in the knowledge and study of the First Empire period.
On his death, he bequeathed his collection, his Parisian mansion and his villa in Boulogne to the Académie des Beaux-Arts, which turned them into the Musée Marmottan (current Musée Marmottan Monet) and the Bibliothèque Marmottan respectively. His donations to the Assistance publique also enabled the creation of the Marmottan Hospital in Paris.
