years he ruled with an iron fist. However, he also displayed humanist tendencies. For example, in 1744 he ordered that the corpse of Joseph Süß Oppenheimer – the executed Jewish financial advisor of his father, Charles Alexander – whose decaying corpse had been suspended in an iron cage by Stuttgart's Prag gallows for six years – be taken down and given a decent burial. He was also well known for his extensive library, his extravagant interest in opera, and interest in large scale horticulture for the feeding of the masses. Between 1751 and 1759 Karl Eugen was involved in an increasingly bitter struggle with his adviser, the eminent Liberal jurist Johann Jakob Moser who strongly opposed the Duke's absolutist tendencies. In 1759 Charles Eugene had Moser charged with authoring "a subversive writing" and cast into prison for the next five years. However, in 1764 Moser was released, due in part to the intercession of Friedrich the Great of Prussia, and was rehabilitated and restored to his position, rank and titles. Charles Eugene died in Hohenheim. Charles Eugene made the first of his five trips to Paris and the Palace of Versailles in 1748 with his first wife. He used these trips to sightsee and acquire Parisian goods for Ludwigsburg Palace while touring the workshops those goods were manufactured in. From 1776 Etienne Sollicoffre, a banker Charles Eugene had met in Paris, befriended the Duke and acted as the agent of his purchases in the city.
