English: Archbishop Annibale Bugnini, C.M. (14 June 1912 – 3 July 1982) was a Catholic prelate. Ordained in 1936 and named archbishop in 1972, he was secretary of the commission that worked on the reform of the Roman Rite that followed the Second Vatican Council. Both critics and proponents of the changes made to the Mass, the Liturgy of the hours and other liturgical practices before and after Vatican II consider him a dominant force in these efforts.[1] He held several other posts in the Roman Curia and ended his career as papal nuncio to Iran, where he acted as an intermediary during the Iran hostage crisis of 1979 to 1981.
