André de Halleux

André de Halleux (1929–1994) was a Belgian Franciscan (ordained 1953), and professor at the University of Louvain at the Theological Faculty (Patristics, theology of Eastern Churches, ecumenical movement, history of dogma) and at the Oriental Institute (Syriac language and literature). Born 18 January 1929 in La Roche-en-Ardenne, he was a corresponding member of the Belgian Academy (1993), a specialist in Syriac literature, in the Council of Chalcedon (451) and its consequences, particularly in the Nestorian and Monophysite spheres (due to his early research on Sahdona and on Philoxenus of Mabbôg). He was awarded with the honorary doctorate of the Institut catholique de Paris, and of the Pontificio Istituto Orientale, Rome. De Halleux was actively involved in oecumenical dialogue, was appointed a consultor to the Pontifical Secretariat for Christian Unity in 1974, and took part in the Vienna 'Pro Oriente' colloquia. After the death of René Draguet, his Syriac teacher, de Halleux became the de facto editor of the Corpus Scriptorum Christianorum Orientalium for 16 years. He died in Uccle Brussels in 1994, January 30.
