Archbishop Annibale Bugnini, C.M. (14 June 1912–3 July 1982) was a main architect of the liturgical reforms in the Roman Catholic Church in the second half of the Twentieth century. He was a controversial figure due to what were seen as two sudden departures from high office. It was rumoured that he was a Freemason, and that this influenced both the departures from office and the "modernising" directions of the liturgical reforms.
