Jean-Baptiste d'Autriche
This attracted attention in high places, and he was soon being sponsored by Klemens von Metternich, who found him employment as chief assistant to the court painter, Johann Baptist Hoechle (1754–1832). In that position, he accompanied Archduke John of Austria and Crown Prince Ferdinand on many of their travels, and produced an album of scenes from Ferdinand's coronation as King of Hungary in 1830. Three years later, he and the new court painter, Johann Baptist's son, Johann Nepomuk Hoechle, collaborated on a series of watercolors showing Ferdinand's pilgrimage to Mariazell.
