1911 Encyclopædia Britannica/Gerard (knight of St John)
GERARD (c. 1040–1120), variously surnamed Tum, Tunc, Tenque or Thom, founder of the order of the knights of St John of Jerusalem (q.v.), was born at Amalfi about the year 1040. According to other accounts Martigues in Provence was his birthplace, while one authority even names the Château d’Avesnes in Hainaut. Either as a soldier or a merchant, he found his way to Jerusalem, where a hospice had for some time existed for the convenience of those who wished to visit the holy places. Of this institution Gerard became guardian or provost at a date not later than 1100; and here he organized that religious order of St John which received papal recognition from Paschal II. in 1113, by a bull which was renewed and confirmed by Calixtus II. shortly before the death of Gerard in 1120.
