Hippolyte Destailleur (27 September 1822 – 17 November 1893) was a French architect, interior designer, and collector.
He is noted for his designs and restoration work for great châteaux in France and in England, as well as his collection of books, prints, and drawings, covering French artists of the 18th and 19th centuries, much of which is now in the Cabinet des Estampes of the Bibliothèque Nationale, Paris (Destailleur Collection).
Hippolyte studied with François-René Leclère at the École des Beaux-Arts in Paris (1842–1846), after which he worked with his father and with Étienne-Hippolyte Godde.
He mimicked French styles of the 16th to 18th centuries, distinguishing himself from many of his contemporaries, who favored medieval, Italian Renaissance, or antique models.
[1] He is one of the best-known foreign architects to have worked in 19th century England, where he designed Waddesdon Manor in Buckinghamshire for Baron Ferdinand de Rothschild (1874–1882) and the Imperial Mausoleum at Saint Michael's Abbey in Farnborough, Hampshire.
