Hasan Balyuzi, loved and honoured throughout the Bahá'í world for his invaluable books on the three Central Figures of the Bahá'í Faith, as well as for other important works, was mourned on his passing by the Universal House of Justice as one of 'the most powerful defenders, most resourceful historians' of the Faith.

He was related to the Báb, and a member of a family distinguished in Iran, but his belief was of conviction and not inheritance. It was his meeting at the age of seventeen with the Guardian, Shoghi Effendi, that stirred him to accept nearly five decades of unceasing labour in administrative, teaching and scholarly fields for the advancement of the Cause. In 1957 he was elevated to the rank of Hand of the Cause of God. The last fifteen years his life were wholly devoted to the writing of the eight books by which he will always be remembered.
