 Raymond du Puy developed the Knights Hospitaller into a strong military force.He is also said to have taken over the management of the "leprosarium" outside Jerusalem that eventually broke off from the Order of St. John to become the Order of Saint Lazarus, becoming its seventh master just before his death.Raymond du Puy divided the membership of the Order into clerical, military, and serving brothers and established the first significant Hospitaller infirmary near the Church of the Holy Sepulchre in Jerusalem.
