Albert Spencer-Churchill, 10th Duke of Marlborough
During the Second World War the 10th Duke first welcomed Malvern College for boys as evacuees to the Palace. After the school was moved to another location, MI5 moved in. The Duke returned to the army as Lieutenant-Colonel and worked as a liaison officer in the British Army with the American armed forces in Britain. The Duchess became head of the Red Cross and worked very hard for them. Later the 10th Duke installed the fountains in the water terrace. This has recently been restored. His main influence at Blenheim was to make the decision to open the Palace to tourists in Easter 1950.
