Saint Théobald was a French deacon and canon regular who lived from approximately 990 to 1070. Born in La Bazeuge, he moved to Dorat to study at the local chapter, motivated by the reputation of Saint Israël. After spending several years completing his education in Périgueux, he returned to Dorat to join the chapter. Although he held significant responsibilities, he chose to remain a deacon rather than seek ordination, driven by his desire for humility.
