Fausto Ernesto Ciurlo was a well-known scholar of the guitar making, diplomed in engineering. He was author of a great deal of articles about this subject and the origins of the guitar and the lute. He was the maker of some innovative models of guitar for his years, e.g. the article about the quarti-tonal guitar mentioned in the bibliography. One of his guitar was played in an old LP recorded by Angelo Gilardino, who was among his friends.
He was the first president of AS.CH.IT. (the Italian Guitar Society), founded in 1960. His well-reputed teacher and friend was Luigi L'Ecrivain, and it is intriguing the fact that nobody asked about him, so it is now a completely forgotten name.
