Raymond du Puy de Provence

Raymond du Puy was a knight from Dauphiné then in the Holy Roman Empire and the second master of the Knights Hospitaller, also known as the Order of St. John of Jerusalem, from around 1121 until 1160. Officially, he succeeded Blessed Gerard, the founder of the Order, as master. While traditionally cited as the direct successor upon Gerard's death in 1118 or 1120, his assumption of the magisterium was in 1121 or 1123 after one or two interim superiors, Pierre de Barcelona and Boyant Roger. Raymond 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.
