Radboud was born around the middle of the 9th century from a noble Frankish family near
Namur. His mother was of Frisian origin and a descendant of the Frisian king
Radboud (died in 719). Radboud began his studies under the care of his maternal uncle
Günther, Archbishop of Cologne, from 850 until his deposition in 863. After that Radboud continued his studies at the court school of the Western Frankish king
Charles the Bald (843- 877), whose chaplain he became. Much of his life was devoted to study and science. After Charles's death, he presumably became a Benedictine monk in the famous Saint-Martin convent of
Tours. In 899 Radboud was elected bishop of the
diocese of Utrecht with the permission of Emperor
Arnulf of Carinthia (887-899). Because
Utrecht was destroyed by the Normans, he did not live there but in
Deventer He had appointed his successor, Balderik, himself. ==Writings==
