Raden Saleh Syarif Bustaman (Ben Jaggia), Prince of Java (c. 1814-1880) was instructed in cartography, perspective, and drawing from life, by the Belgian painter Antoine Payen. In 1829 he accompanied Payen to the Netherlands, where he was instructed by the history painter Cornelis Kruseman, and later by the landscape painter Andreas Schelfhout. Although he was urged to strive for financial independence, Saleh was wholly reliant on the Dutch State throughout his ten year stay in the Netherlands until his departure for Dresden in 1839. Whilst in the Netherlands he painted copies after such masters as Rembrandt and Van Dyck, in addition to executing portraits of Dutch statesmen. From Dresden Saleh travelled to Austria, Italy and France, returning to the Hague in 1844, where William II made him a Companion of the Order of the Oak Crown in recognition of his artistic achievements. During this period he executed commissions for many European patrons, establishing a reputation for portraiture and animal subjects. In 1845 he went to Paris, where he befriended Horace Vernet, and together they travelled to Algiers. In 1851 he settled in Java, where he painted his best-known works- wild animals in the style of Delacroix- as well as stag hunts and forest fires. Many of his works were displayed at the Great Colonial Exhibition of 1883, in Amsterdam.

Prince Alexander, Count Alexander von Mensdorff-Pouilly (1813-1871) was the son of Count Emanuel and a cousin of Queen Victoria (his mother was the Duchess of Kent's elder sister). She called him ‘the best of them all, – he is so excellent and so kind’. He served at the courts of Coburg and Lisbon and then entered the Austrian service, winning distinction in the army and the Ministry of Foreign Affairs. He became Governor of Bohemia and was made a Prince.
