Pierre Nommesch (16 December 1864 – 9 October 1935) was the Bishop of Luxembourg from 1920 to 1935.
He became bishop after a long period of sede vacante, which was due to challenges to Luxembourg's national sovereignty following the Armistice of World War I.
[2] His time in office was marked by reconciliation and understanding between state and the church:[2] The conflict around schools received a compromise solution in 1921, so that religious education, relegated to church parishes since 1912, once again had a place in public education.
[2] Under his episcopate, loyalty to the monarchy and to Luxembourgish traditions, closeness to Rome (with pilgrimages to the "holy city", and celebration of the papal coronation anniversaries), and veneration of the Virgin Mary (expansion of the cathedral, started in 1935) remained important facets of Luxembourgish Catholicism.
[2] Further religious-pastoral highlights of his time in office included the Eucharistic National Congress in 1924, increased devotion to the Sacred Heart, the rebuilding of the seminary at Limpertsberg in 1930, and consolidation of associations in the Belgian-inspired Catholic Action after 1930.
