Theobald of Bec, French-English archbishop (b. 1090)
Theobald of Bec (c. 1090 – 18 April 1161) was a Norman archbishop of Canterbury from 1139 to 1161. His exact birth date is unknown. Some time in the late 11th or early 12th century Theobald became a monk at the Abbey of Bec, rising to the position of abbot in 1137. King Stephen of England chose him to be Archbishop of Canterbury in 1138. Canterbury's claim to primacy over the Welsh ecclesiastics was resolved during Theobald's term of office when Pope Eugene III decided in 1148 in Canterbury's favour. Theobald faced challenges to his authority from a subordinate bishop, Henry of Blois, Bishop of Winchester and King Stephen's younger brother, and his relationship with King Stephen was turbulent. On one occasion Stephen forbade him from attending a papal council, but Theobald defied the king, which resulted in the confiscation of his property and temporary exile. Theobald's relations with his cathedral clergy and the monastic houses in his archdiocese were also difficult.

Serving during the disorders of Stephen's reign, Theobald succeeded in forcing peace on the king by refusing to consecrate Stephen's son and heir, Eustace. After Eustace's death in 1153, Stephen recognised his rival Henry of Anjou as his heir, and later Theobald was named regent of the kingdom after Stephen's death. After a long illness, Theobald died in 1161, following which unsuccessful efforts were made to have him canonised as a saint.

Theobald was the patron of his successor Thomas Becket, and a number of other future bishops and archbishops served as his clerks. During his time as archbishop Theobald augmented the rights of his see, or bishopric. Historians of his time and later were divided on his character and he is often overlooked in the historical record, mainly because of the fame of his successor.
