In this period the young Urhan shared lodgings with his friends, the harpist Franz Anton Stockhausen (father of Julius Stockhausen), and the painter Carl Joseph Begas the elder (who was studying with Antoine-Jean Gros from 1813 to 15). In 1815, through a quartermaster in the Prussian army of occupation, Urhan and Stockhausen (who corresponded with Ludwig van Beethoven) obtained a score of Beethoven's "Eroica" Symphony and set it before Habeneck, with the result that the work was introduced to Paris. The two were among "Amis de Beethoven", or "Beethoven-Brüder" in Paris, together with Wilhelm Mangold and others. In the early 1820s, the violinist Sina, a member of the string quartet led by Schuppanzigh for Andrey Razumovsky, gave Urhan new encouragement to continue with the master's works. Until Stockhausen's marriage to the singer Margarethe Schmuck, a member of their circle in 1825, he lived with Urhan, who remained a lifelong friend.
