The original typed and signed letter by Professor William F. Albright (Johns Hopkins University) in which he reacts to the first images of the Great Isaiah Scroll. In the weeks prior, Professor John C. Trever photographed several Dead Sea Scrolls in Israel and airmailed images to Albright. This letter contains Albright’s first reaction to the Great Isaiah Scroll, referring to it as “the greatest [manuscript] discovery of modern times!” and “an absolutely incredible find!” Though it was an initial assessment, further studies supported Albright’s dating of the Great Isaiah Scroll to “around 100 B.C.”
