However, despite some difficulties, the family business survived and prospered under the new regime. In addition to his banking business, in 1868 de Rothschild purchased Château Lafite, one of France's most outstanding vineyards. Located in the Bordeaux region, it is a business that remains in the family to this day. On 11 July 1824, in Frankfurt, Germany, de Rothschild married his niece Betty Salomon von Rothschild (1805–1886), the daughter of his elder brother, Salomon Mayer von Rothschild (1774–1855). They had the following children:   De Rothschild and his sophisticated Viennese wife were at the center of Parisian culture. The chef for their lavish receptions was Antonin Carême. They patronized major personalities in the arts, including Gioacchino Rossini, Frédéric Chopin, Honoré de Balzac, Eugène Delacroix, and Heinrich Heine. As an acknowledgment of the many years of patronage extended by Baron James and his wife Betty, in 1847 Chopin dedicated his "Valse Op. 64, N° 2 in C sharp minor" to their daughter Charlotte. In 1848 Jean Auguste Dominique Ingres painted Betty de Rothschild's portrait. In 1817, de Rothschild purchased Château Rothschild in Boulogne-Billancourt, where his children were born and reared. In 1838 he purchased from Charles Maurice de Talleyrand a large residence in Paris, at 2 rue Saint-Florentin on the Place de la Concorde. It remained in the family until 1950, when it was sold to the United States government; today it serves as the consular section of the American Embassy. In 1854 de Rothschild commissioned the famous architect Joseph Paxton to build the Château de Ferrières in Ferrières-en-Brie, some east of Paris. The property remained the home of his inheriting male descendants until 1975, when Guy de Rothschild gave it to the University of Paris. Beyond his business activities, de Rothschild made the first significant acquisitions for what became the French family's massive art collections. His art included Vermeer's 1668 work "The Astronomer". According to the painting's provenance, it was seized by the Nazis in 1940 but after World War II the painting was returned to the family. In 1983, in lieu of payment of inheritance taxes, the painting was given to France and has been displayed by the Louvre since that time.
