Daniela De Gregorio
I was born in Spoleto, Italy, in 1950, an only child. I studied Philosophy and History at the University of Perugia, and I began to work as a journalist and an art critic. When Mike came to Italy (we were married in Fiesole in 1980), we lived in Mestre in the north of Italy, and I began to teach in Venice. My father, Giuseppe De Gregorio was a renowned abstract painter, while my mother had been elected 'Miss Spoleto' shortly after the Second World War.
There was only one avenue left open to me - writing!

Michael G. Jacob
I went to a Roman Catholic grammar school in Liverpool. After studying English at Newcastle university, I graduated B. A. (Hons) in 1970. I taught Eng Lit for nine years, then moved to Italy in 1980 when Daniela and I were married. In my spare time, I collect historical photographs, daguerreotypes for the most part. In 1992, I published an account in Italian of how the very first photographs on metal plates (i.e., daguerreotypes) were coloured by hand or by electrolysis: Il Dagherrotipo a Colori (Florence: Nardini Editore) is still in print. It was, of course, translated by Daniela De Gregorio!
