The younger of Sir Sultan Mahomed Shah''s two sons, Prince Sadruddin was the uncle of the present and 49th hereditary Imam (spiritual leader) of the Ismaili Muslims, His Highness the Aga Khan.
The Aga Khan traces his lineage back to the Prophet Muhammad (peace be upon him) and Prince Sadruddin''s grandmother was the granddaughter of the Qajar Emperor Fath'' Ali Shah.
Born in Paris, France on 17th January, 1933, Prince Sadruddin received his early education in Switzerland before graduating in 1954 from Harvard University.
After three years of post-graduate research at Harvard''s Centre for Middle Eastern Studies, Prince Sadruddin followed a family tradition in international service established by his father who had served two terms as President of the League of Nations.
Widely known for his generosity and warm personality, Prince Sadruddin was highly regarded and greatly respected by family and friends and held in deep affection by the Ismaili Muslim Community around the world.
His support for the Community and for the work of the Ismaili Imamat in improving the quality of life for people across the developing world was unfailing. Prince Sadruddin is survived by his wife of 31 years, Princess Catherine (formerly Catherine Aleya Sursock) as well as his nephews,
His Highness the Aga Khan, Prince Amyn Aga Khan, his niece, Princes Yasmin Aga Khan Embiricos, and his stepsons, Alexandre, Marc and Nicholas Sursock. (The Financial Express)
