Guglielmo Libri Carucci dalla Sommaja

Guglielmo Libri Carucci dalla Sommaja was an Italian count and mathematician, who became known for his love and subsequent theft of ancient and precious manuscripts. After being appointed the Inspector of Libraries in France, Libri began stealing the books he was responsible for. He fled to England when the theft was discovered, along with 30,000 books and manuscripts inside 18 trunks. In France, he was sentenced to 10 years in jail in absentia; some of the stolen works were returned when he died, but many remained missing.
