Pierdomenico Baccalario

From Wikipedia, the free encyclopedia

Pierdomenico Baccalario (born 6 March 1974)[1] is an Italian author of children's and young adult fiction, best known for his Ulysses Moore series that sold more than 10 million copies worldwide.


Pierdomenico Baccalario was born in Acqui Terme, Italy, in 1974.[2] He studied law in university, but he continued to write, a passion that he had had since high school, and published his first book, ′′La strada del guerriero′′ in 1999. The book was popular in Italy but was never translated into English.

In 2004 he published the first of so far 18 novels in the Ulysses Moore series, which has since been translated in 29 languages and sold 10 million copies worldwide.[3]

Baccalario lives part time in Italy and part time in London with his wife Marina Della Giusta, a professor of economy at the University of Reading, and their two daughters. He is the founder of Book on a Tree, a company with some 15 employees, publishing 60 books a year.[3]

In 2019 he was shortlisted for the Premio Strega for author's writing for children (age 11+).[4]
