Please answer the following question: What is the answer for the question: What is the first name of the person who only managed to finish the Alter Hauptbau's (Old main building) first floor and some of the southern garden before 1707? from the following article ?  "Ludwigsburg," meaning "Louis's castle," was named after its builder, Eberhard Louis, Duke of Württemberg, in 1705. It had been previously known as the Erlachhof, a traditional hunting estate and lodge of the Dukes of Württemberg that was destroyed in 1692, during the Nine Years' War. Eberhard Louis commissioned a replacement lodge that was built from 1697 to 1701. Construction was interrupted by the beginning of the War of the Spanish Succession, fought against France and Bavaria. Württemberg resisted entry into the war until late 1702. Two years later, Eberhard Louis participated in the Battle of Blenheim in August 1704 that was followed by the exile of the Bavarian Elector. The duke used the battle to press claims to Bavarian lands, but he illegally occupied those lands and was further weakened by a French invasion of Württemberg in 1707. As a result of this attack, the ducal residence in the capital, Stuttgart, was burned and the royal family fled to Switzerland. With the Treaty of Utrecht in 1713, the occupied Bavarian territory and status of the exiled Elector were restored.Construction of Ludwigsburg Palace began in May 1704 with the laying of the Alter Hauptbau's cornerstone by Eberhard Louis. The year before, he sent Philipp Joseph Jenisch to study architecture abroad. Eberhard Louis made Jenisch director of construction upon his return the next year, but he only managed to finish the Alter Hauptbau's (Old main building) first floor and some of the southern garden before 1707. The duke spent the winter of 1705–06 at Nymphenburg Palace, residence of the Elector of Bavaria, and was impressed by what he saw there and in architectural publications. Unable to compete with Bavaria militarily or politically, and defiant following the loss of the Stuttgart residence, Eberhard Louis decided to follow the example of Bavaria, Baden-Durlach, and the Rhineland Palatinate. He elected to build a new palace and town inspired by Versailles, which would be the center of his domestic society and diplomacy. Located 10...
