Waldebert (also known as Gaubert, Valbert[1] and Walbert), (died c. 668), was a Frankish count of Guines, Ponthieu and Saint-Pol who became abbot of Luxeuil, and eventually a canonized saint in the Roman Catholic Church and Eastern Orthodox Church.
Like several among his kinsmen, he protected the Church, enriched it with lands and founded monasteries.
[2] Like his predecessor at Luxeuil he was born of the noble Frankish family of Duke Waldelenus of Burgundy, highly influential in seventh-century Frankish politics[3] and served in the military before dedicating himself to the contemplative life and joining the monastery at Luxeuil on the borders of Austrasia and Burgundy (in modern-day France), where he dedicated his weapons and armour, which hung in the abbey church for centuries.
[5] He also gained from Pope John IV the independence of his community from episcopal control and increased the size and prosperity of the monastery's territories and buildings.
The basic modern study is that in J. Poinsotte, Les abbés de Luxeuil (1900).
