At a garage sale in Minnesota in 1989, a young American photographer, John Barnier, bought eight wooden crates containing over 130 glass plate negatives. Realizing that many of the negatives were of Jerusalem, he brought them to the Harvard Semitic Museum where they were eventually identified as the long-lost work of Mendel John Diness, who lived in Jerusalem in the 1850s and was the first photographer to learn--and practice--the art there.
