Bruno was appointed to succeed Bishop Amelung, brother of Hermann Billung, in 962.
According to Thietmar of Merseburg, Hermann's son Bernard, while transporting his father's body to Lüneburg, encountered Bruno and tearfully asked that his father be granted absolution and permitted burial at the church.
[1] Bruno was held in high regard by the emperor who had designated him successor to Amelung.
Because stone was not available, Amelung had erected and consecrated a magnificent wooden church, surpassing all others in size and quality.
As Bruno grew old, Emperor Otto II asked that his chaplain Herman, brother of Folkmar (Volkmar), Archbishop of Cologne, be designated as assistant and heir.
