Théodore Alexis Joseph de Montpellier (1807âÂÂ1879) was the 85th bishop of Liège in Belgium.
Montpellier was born in the castle at Vedrin on 7 May 1807. His secondary education was at the Bishop's College in Aalst and the Jesuit College in Amiens. He then studied Theology in Rome, where he was ordained to the priesthood on 7 September 1833.
Returning to the diocese of Namur, he was in considerable demand as a retreat master for religious congregations and societies. The bishop of Namur, Nicolas-Joseph Dehesselle, appointed him to establish the first Catholic normal school in modern Belgium, at Malonne. Montpellier was also one of the founders of the newspaper L'Ami de l'ordre. On 27 February 1843, he was appointed inspector of primary schools for the diocese of Namur.
On 27 September 1852, Pope Pius IX confirmed Montpellier's appointment as bishop of Liège in succession to his recently deceased friend, Cornelius van Bommel. He was consecrated on 7 November.
As bishop, Montpellier encouraged the foundation of hospices, hospitals and orphanages; the building of new parish churches (consecrating 88 in person); and the establishment in his diocese of many religious orders and congregations, especially those running schools. He also helped fund the establishment of a school of mining, an anatomical theatre and a pedagogical institute at the Catholic University of Leuven. He frequently preached Advent and Lenten missions in the major churches of his diocese, and led annual retreats for his clergy. He actively opposed Liberal legislation to suppress religious processions and funerals, reallocate the income of Catholic parishes and schools, and subject seminarians and clergymen to military conscription. His zeal led Pope Pius IX to describe him as "a fire burning on the altar for God and for the Church". He died in Liège on 24 August 1879.
