Waldo of Reichenau

His father was Richbold Count of Breisgau and his older brother was Rupert Baron von Aargau.

He entered the Abbey of Reichenau in 784 under Abbot Peter, brother of Hildegard, Charlemagne's second wife.

Under Waldo, the library and scriptorium of Reichenau Abbey "grew to rival the finest in the Frankish kingdom".

He sent the monk Odilleoz, brother of Haito, head of the monastic school at Reichenau, to Tours to study under Alcuin.

According to Johannes Fried, Waldo served as one of the advisers of the young Pepin of Italy.
