French prince, as a member of the House of Orléans who held the title of Prince of Condé. He was the first member of a royal house to visit the Australian continent.
He was the eldest son of Henri d’Orleans, Duke of Aumale and his wife, Princess Maria Carolina of Bourbon-Two Sicilies.
Following the outbreak of the French Revolution of 1848, he and his family went into exile in England.
When Louis d’Orléans was 20 years old, his father arranged an 18-month world tour for him. In the view of his father, a journey through climes beyond the borders of Europe would improve his ailing health. Together with his doctor, Paul Gingeot, and his cousin, Prince Ferdinand, Duke of Alençon, Louis d’Orléans began his journey on 4 February 1866 in Southampton on the Mongolia, a passenger ship owned by British shipping line, Peninsular and Oriental Steam Navigation Company (P&O). The itinerary was to take him to Egypt, Ceylon, Australia, New Zealand, Java, China, Japan and India. Louis d’Orléans was especially interested in Australia; he was fascinated by its exotic nature.
After a short stay in Ceylon, they continued their travels on the P&O liner, Bombay.
On 8 April the Bombay reached King George Sound, a bay on the southwest coast of Western Australia. Louis d’Orléans went ashore at Albany.
On 13 April the Bombay entered the port at Melbourne. Louis d’Orléans, who wanted to get to Sydney as soon as possible, decided to visit the city on his return journey. On 16 April 1866 the Bombay tied up at Port Jackson. D’Orléans was very impressed by the town and compared it to old towns around the world.
Over the next five weeks, d’Orléans, whose health had markedly improved, went to various social occasions.
On 12 May 1866 he received news of the death of his grandmother, Maria Amalia of Naples and Sicily, which affected him badly and this, together with a cold, caused his health to noticeably worsen. After a short-lived improvement, his health deteriorated rapidly. On the evening of 24 May, Louis d’Orléans died in Sydney in the presence of Dr. Gingeot. On his death, the title of Prince of Condé died out.
