Joseph Jay Deiss

In 1971, for his historical work relating to Italy, he was Knighted by that government. In his later years, Deiss devoted his time to both Cape Cod and his home in Gainesville, Florida, where he was an adjunct professor in the Classics Department of the University of Florida. Joseph Jay Deiss died on April 10, 1999. He was predeceased by his wife, Catherene (Dohoney), son John Casey ("Casey"), and was survived by his daughter, Susanna, and grandchildren.

In 1957 Deiss, living in Positano, Italy, began in depth research at museums and academic institutions in Germany, Austria, and Italy that led to his third work, a biographical novel, The Great Infidel, about Frederic the Second, Holy Roman Emperor and King of Sicily. While Deiss was involved in his biographical novel of Frederic the Second, he was drawn to the ancient monument cities of Herculaneum and Pompeii, spending time there since they were near his home in Positano. On becoming Vice Director of the American Academy in Rome, he actively started exploring these ancient cities. Out of this effort he wrote, Herculaneum, Italy's Buried Treasure. This was followed by Captains of Fortune, which consisted of profiles of six famous Italian Condottieri (soldiers of fortune) from the medieval period to the renaissance. The eclectic interests of Deiss in historical Italy finally led to his The Roman Years of Margaret Fuller.
