Simpert was an influential 8th-century Benedictine abbot and bishop who served the diocese of Augsburg. Born around 750, he received his education at Murbach Abbey in Alsace, where he eventually became the abbot. According to tradition, he was a nephew of Charlemagne, who appointed him to his episcopal position in 778. Throughout his leadership, he balanced his duties as a monastic ruler and a diocesan bishop, moving between several locations including Neuburg an der Donau and Staffelsee Abbey.
