Princess Hilda of Luxembourg (1897–1979)

Princess Hilda of Luxembourg (Hilda Sophie Marie Adélaïde Wilhelmine de Nassau-Weilburg, Princesse de Luxembourg; 15 February 1897 – 8 September 1979) was a Princess of Luxembourg by birth and the Princess of Schwarzenberg by marriage.

Early life
Hilda was the third daughter of William IV, Grand Duke of Luxembourg, and his wife, Infanta Marie Anne of Portugal. Her two eldest sisters reigned as sovereign Grand Duchess of Luxembourg and titular Duchess of Nassau: Marie-Adélaïde and Charlotte.

Marriage
Princess Hilda married with Adolf, 10th Prince of Schwarzenberg (Frauenberg, 18 August 1890 – Bordighera, 27 February 1950) in Berg Castle on 29 October 1930. The couple shared a passion for agriculture, wildlife and botany and spent much of their time at their Stará Obora hunting lodge near Hluboká. They acquired Mpala Farm in Laikipia, Kenya, in 1933. Apart from bringing modern farming methods to the estate, Princess Hilda's husband built a hydroelectric power station there (some of the machinery was imported from his native Hluboká) and made exceptional improvements to his workers' living conditions. He inherited the family estates after his father's death in 1938. They did not have children.
