Leroy C Ioas (15 February 1896, Wilmington, Illinois - 22 July 1965, Haifa, Israel) was a Hand of the Cause of the BaháüàFaith. His parents declared themselves BaháüÃÂs in 1898 and took Ioas to meet ûAbdu'l-Bahá during the latter's travels in the United States in 1912. Ioas moved to San Francisco after marrying Sylvia Kuhlman and soon became active in the local Baháüàcommunity.
The head of the BaháüàFaith in the first half of the 20th century, Shoghi Effendi, appointed Ioas to the International BaháüàCouncil, precursor to the Universal House of Justice, in December 1951, where he served until 1961 as secretary-general. In order to fulfill his duties, he quit his job in the railway industry, where he had worked for nearly forty years, and moved to Haifa, where he would reside until the end of his life.
He closely supervised the construction and completion of the Shrine of the Báb, for which Shoghi Effendi named the door on the octagon after him.
After the death of Shoghi Effendi, Ioas was among nine Hands of the Cause elected as a Custodian of the BaháüàFaith on 25 November 1957. He travelled far and frequently to promote and expand the faith, even as his health weakened after heart problems began in 1953. His last trip, to eight areas in the United States during 1964, weakened him so much that he could not return to Haifa for six months and died less than a year later. He is buried in the Mount Carmel Baháüàcemetery in Haifa.
