Ngô Đình Thục

Pierre Martin Ngô Đình Thục was a Vietnamese Catholic prelate who served as the Archbishop of Huế in the Republic of Vietnam from 1960 until 1968. He later lived in exile in Europe due to the unrest in his country and became a sedevacantist, consequently excommunicated twice by the Catholic Church. Five months before he died, he repented his views and was received back into the Church.
