Mike Butterworth is primarily known in comic circles as the writer of The Rise and Fall of the Trigan Empire, but had previously written Battler Briton and Buffalo Bill strips for Comet, for Sun he wrote Max Bravo, The Happy Hussar and Billy the Kid (which was drawn by, amongst others, Don Lawrence). The Trigan Empire began in 1965 in Ranger, and continued when Ranger was absorbed into Look and Learn where it continued to be published through to 1982. From 1967 he also wrote crime novels under his full name, John Michael Butterworth, and gothic romances under the pseudonyms of Carola Salisbury and Sarah Kemp. Don Lawrence was born in 1928, and worked for Mick Anglo on the Marvelman comic produced for Amalgamated Press, and then Billy the Kid in the comic Sun. When Sun was absorbed into Lion he moved on to illustrating Olac the Gladiator, Karl the Viking and Maroc the Mighty. In 1965 he teamed with Mike Butterworth to create The Rise and Fall of the Trigan Empire for Ranger magazine, and continued to paint the comic through its transition into Look and Learn through to 1976. During this period he also worked on Fireball XL5 and The Adventures of Tarzan comic strips for TV Century 21. After leaving The Trigan Empire he worked with a Dutch publisher to create Storm, a post-apocalypse sci-fi series, which he would draw through to his retirement in 1999.
