Ugo Giachery (May 13, 1896 – July 5, 1989) was a prominent Italian Bahá'í from an aristocratic family from Palermo. At an anniversary of the founding of the spiritual assembly of PerugiaGiachery told the story of how, as a young wounded soldier, still ignorant of the Bahá'í Faith, he was in Perugia in 1916. After World War I he moved to the United States, where he became a Bahá'í around 1926. In 1947, his family moved back to Rome in Italy. He translated many Bahá'í books into Italian. From 1948 he started taking care of the marble supplies from Italy for the superstructure of the Shrine of the Báb and the International Archives Building.
He was appointed a Hand of the Cause by Shoghi Effendi in December 1951, who also appointed him as a member-at-large of the International Bahá'í Council, and who named one of the doors of the Shrine of the Báb after him.
Ugo Giachery, Hand of Cause, has written not only a biography, but his personal experiences of Shoghi Effendi, Guardian of the Bahai Faith.
