4.  He worked as a butcher's boy, helping in the shop from the age of three.  He joined the electricity board as a management trainee when he was 18.  Then went to a drama company in 1972 as an actor bringing theatre to children.  He qualified as a teacher and taught drama.  He began writing in 1976, turning full- time in 1994, with the publication of the Horrible Histories series.

5.  The Horrible Histories series of books are popular among children for their disgusting details, gory information and humorous pictures and among adults for getting children interested in history.  Books in the series have been widely translated into other languages.  A cartoon series has been made of his books and was shown on CiTV in 2002.

7. Did you always love history when you were young?  I hated history. History was the most boring subject in the universe, because the teacher had some notes and he had learned these at college 30 years ago. And he read them to us and we copied them down word for word. It was about as exciting as a hibernating tortoise.  There were no stories or exciting adventures. Or bits about what it was really like to live in the past.  So when I wrote Horrible Histories they were anti-school. They were the things they don't tell you in school or the things that my teacher didn't tell me.  Sometimes children read my books and they get all excited about history and they go to school saying history is their favourite subject. Don't blame me!!!

8.  Deary received an Honarary Doctorate of Education from the University of Sunderland in 2000.  In 2011, he retired from writing children's books after 35 years.  Terry Deary has called to "ban Horrible Histories from schools", because "classrooms take all the fun out of his stories!!
