Peter Dennis was born in 1950. Inspired by contemporary magazines such as Look and Learn he studied illustration at Liverpool Art College. Peter has since contributed to hundreds of books, predominantly on historical subjects, including many Osprey titles. A keen wargamer and modelmaker, he is based in North Wales.
While primarily a military and historical illustrator, he prides himself on the wide scope and variety of commissions he has taken on. One of his latest works has been the black and whte sketch-style illustrations done for Sir Terry Pratchett's The World of Poo. His association with the Discworld continues: as well as illustrating the Ankh-Morpork Boardgame, he has most recently illustrated Mrs Bradshaw's Handbook and the 2016 Discworld Diary. He also provided the full-colour illustrations in The Compleat Discworld Atlas.
