Louis-Martin Berthault was born in Paris on 30 September 1770 into a wealthy family of Paris entrepreneurs. Before the
French Revolution of 1789, Berthault organized balls for the Comte d'Artois, who later became
Charles X of France. Berthault established a clientele among those who had gained riches in the revolution. In 1801, the Duchess of Brissac sold the
Château de Pontchartrain to the industrialist and speculator
Claude-Xavier Carvillon des Tillières, a leader of the "Black Band" syndicate of businessmen enriched by the
Directory who specialized in the purchase and liquidation of the great aristocratic estates. Carvillon engaged Berthault to transform the gardens from the French style to that of an English park. After the Empire was established in 1804, Berthault extended his clientele to aristocrats who returned from exile and regained possession of their property. Berthault served
Napoleon as a landscape architect, succeeding
Jean-Marie Morel at Queen
Hortense's residence at the
Château de Saint-Leu in
Taverny. Berthault designed the parks of
Compiègne and
Malmaison in the English style, and was the architect responsible for the renovations of the Château de Compiègne. A
Sèvres porcelain basket to hold flowers or fruit, now held in the
Metropolitan Museum of Art, was designed by Berthault in 1814. After the
Bourbon Restoration in 1814, Berthault continued to serve an elite clientele. Baron
James de Rothschild undertook major changes to his mansion on rue Laffitte between 1820 and 1825. Berthault was hired to make the stairway wider, and to build a ballroom over the garden capable of holding 3,000 guests. Berthault also organized several of the balls, and provided floral decorations. He organized a ball on 3 March 1821 attended by over 1,500 people at which each lady received a bouquet of flowers and also a diamond ring of brooch. Louis-Martin Berthault died at Tours on 16 August 1823. ==Works==
