Mah-Jongg or Jongy was a ring-tailed lemur owned by Virginia and Stephen Courtauld, wealthy English philanthropists from a family of industrialists.
Jongy was purchased at Harrods, one of London's most upmarket department stores, in 1923 and lived with the Courtaulds for fifteen years, accompanying the couple on their travels and changes of residence.
[1][2] The Courtaulds refurbished Eltham Palace in the 1920s into an Art Deco mansion for entertaining, and had Jongy's likeness incorporated into artistic details.
In Leonard Campbell Taylor's portrait of the Courtaulds in the music room of their London townhouse (47 Grosvenor Square), Jongy sits next to Virginia, on the arm of her chair.
Stephen Courtuald sponsored the 1930-31 British Arctic Air Route Expedition, for which his cousin Augustine Courtauld served as metereologist.
