Gustave Adolphe Désiré Crauck (or Crauk; 16 July 1827 – 17 November 1905) was a French sculptor with a long distinguished career.
He was born and died at Valenciennes, where a special museum for his works was erected in his honor. Educated at the École des Beaux-Arts, Crauck took the Prix de Rome in 1851.
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.
