Elie Lainé was a Paris-based landscape architect who created the terraces, roads and plantations for the park at Waddesdon Manor for Ferdinand de Rothschild. According to the Waddesdon account books, he was active there from at least 1876 until 1887, and led the work that turned a muddy, windswept hill into what is now a Grade I registered landscape. He also led the restoration of Le Nôtre's great gardens at Vaux le Vicomte, south of Paris, from around 1876, and designed the grounds at the chateau d'Armainvilliers in Seine-et-Marne from 1881 for Edmond de Rothschild. In 1888 Ferdinand de Rothschild recommended Lainé to the Belgian king, Léopold II, and he worked on royal estates for the next fifteen years or so. His projects for Léopold included town planning, road design, installing major hydraulic systems and creating mature woodlands.
