c.990-1073. Founder of the [[Vallumbrosan Order]]. Originally he was a member of the Benedictine monastery at San Minato, near Florence. After four years there he joined the monastery at Camaldoli, and some time later moved to Vallumbrosa, a city probably near Florence, where he formed his own monastic settlement. The Rule of the Vallumbrosan Order was a modified Benedictine, in some ways more austere, and it particularly excluded manual labor. The order eventually included the institution of lay brothers. Traditional date for the founding of the order is about 1300. [[John Gualbert]] has been canonized by the Roman Catholic Church.
