 The first prior of the abbey was Burkhard sent by Norbert of Xanten from the mother house Prémontré near Laon in northern France together with twelve monks.Burkhard's work was so successful that in 1137 the first filial institution was founded in Wilten near Innsbruck following a request by bishop Reginbert of Brixen.Burkhard's successor, abbot Ottino (1140–82), led the monastery, consisting by now of approximately 200 monks, to its first prosperous period and increased the number of filial institutions.
