What is the full name of the person who started in the Ahengalerie and the Ordensbau, working there from 1803 to 1806?
Napoleon's armies occupied Württemberg from 1800–01, forcing the duke and duchess to flee to Vienna. The royals returned when Frederick II agreed in 1803 to pledge allegiance to Napoleon and part with Württemberg's territory on the Left Bank, an area of 388 square kilometers (150 sq mi). In exchange, according Treaty of Lunéville, Frederick II was named an Elector-prince and given 1,609 square kilometers (621 sq mi) of Right Bank territory. Frederick II, now Elector Frederick I, now tasked his court architect Nikolaus Friedrich von Thouret with renovating the palace in the Neoclassical style. Thouret started in the Ahengalerie and the Ordensbau, working there from 1803 to 1806. For two days in October 1805, Napoleon visited Ludwigsburg to coerce Frederick I into joining the Confederation of the Rhine and thus becoming his ally, compensating Württemberg with neighboring territories in the Holy Roman Empire and Frederick I with the title of King. Frederick I again tasked Thouret with a remodeling, from 1808 to 1811, of the Ordenskapelle and the king's apartment. The final modernizations ordered by the king took place from 1812 to 1816 in the Schlosstheater and Marble Hall. During this time, the ceiling frescoes of the Guard Room and the main staircases of the Neuer Hauptbau were repainted. By the time Frederick I died in 1816, the majority of the palace had been converted to reflect the latest style.Following her husband's death, Charlotte continued to reside at Ludwigsburg, receiving visitors such as her siblings. She tasked Thouret with the renovation of her own apartment, which was carried out between 1816 and 1824. The dowager queen died at the palace on 5 October 1828 following a bout of apoplexy. Charlotte was the last ruler of Württemberg to reside at Ludwigsburg, as Frederick's son and successor, William I, and future kings did not show any interest in the palace. Members of the House of Württemberg continued to reside at the palace into the early 20th century, while the Württembergs moved to Bebenhausen Abbey after the abolition of the monarchy in 1918.
