Bruno of Querfurt
Missionary archbishop and martyr
Feast: 9 March (not on the universal Roman calendar; kept in the Roman Martyrology or local calendars)
Who they were
Bruno, of the noble family of Querfurt, was educated at Magdeburg and became a canon there while still a boy. Emperor Otto III took him to Rome in 996, where he came to know St Adalbert of Prague. After Adalbert's martyrdom among the Prussians, Bruno burned with desire for martyrdom and became a monk.
Made archbishop for the missions by Pope Sylvester II, he preached to the pagans of the East and was killed with his companions on 14 February 1009. From their death they were honoured as martyrs; he is called the second Apostle of the Prussians.
The miracles
There was never a formal cause: he has been honoured as a saint since before the Church's formal processes began.
Why that counted as sanctity
