A ring-tailed lemur who famously once lived in Eltham Palace, Mah-Jongg was the much-indulged pet of rich-listers Stephen and Virginia Courtauld during the interwar period.

The couple purchased the lemur through Harrod’s then pet department soon after their marriage in 1923. He was immediately christened Mah-Jongg but commonly referred to as “Jongy”.

As well as residing with them in their Grosvenor Square, Mayfair, residence, the lemur also travelled with the Courtaulds.

This included on their luxurious motor yacht, the Virginia, on which he had a specially designed deck chair to lounge in (although Jongy, who had a reputation for being a bit nippy at times, is said to have disgraced himself at a farewell lunch for the British Arctic Air Route Expedition, of which Stephen was a sponsor, when he bit the expedition’s wireless operator, Percy Lemon, and severed an artery; it took Lemon three months to recover).

When the Courtaulds bought Eltham Palace in 1933, Mah-Jongg’s image was incorporated into the building including in a mural in the billiard room and in wooden bosses carved in his likeness in the Great Hall.

Mah-Jongg also had specially designed living quarters on the first floor with a trapdoor opening to a bamboo ladder that led down to the Flower Room on the ground floor. His cage was decorated with Madagascan rainforests by Gertrude Whinfield.

Mah-Jongg died in 1938. A memorial to him was originally installed at Eltham Palace but is now located at the Courthauld’s last home, a replica French villa called La Rochelle, in what is now Zimbabwe.

He’s also famously seen in Leonard Campbell Taylor’s 1934 portrait of the Courthaulds in the music room of their Grosvenor Square home.
