On February 18, 1948, Father Butrus Sowmy of St. Mark's Monastery called the American Schools of Oriental Research (ASOR) to contact William Brownlee, a Fellow at the ASOR, about publishing the Great Isaiah Scroll, the Habakkuk Commentary, and the Community Rule. Brownlee was away from the school temporarily, so Sowmy was put in contact with Dr. John Trever, photographer and temporary director of the school.[17] Trever photographed the scrolls and sent the photographs to palaeographer and dean of American archaeologists, Professor William Albright of Johns Hopkins University, who dated the manuscript of Isaiah at around 100 BCE.[17]
