Butrus Sowmy
Librarian and monk of Saint Mark's Syrian Orthodox Monastery in the Armenian quarter of the Old City of Jerusalem. He found the Dead Sea Scrolls while cataloguing rare books in the monastery's collection.
Dead Sea Scrolls
On February 18, 1948, Butrus Sowmy called John C. Trever, acting director of the American Schools of Oriental Research (ASOR), about some scrolls in ancient Hebrew that had been in the monastery for about 40 years as he was preparing a catalogue of the monastery's collection of rare books.
Sowmy and his brother brought five scrolls to Trever the next day. Trever realized the significance of the finding and studied them.
However, when the ASOR director Millar Burrows joined the study, the Syrians revealed the scrolls had not been in the monastery for 40 years - they had been purchased in 1947.
