Oliver Frey was born in Switzerland, but has lived in the UK for many years. He studied film at the London School of Film Technique and began drawing comic strips to earn a living, working for Fleetway's picture libraries. After briefly running a film company in Switzerland, Frey returned to the UK and worked as a full-time comic strip artist and illustrator. He drew two of his favourite boyhood comic strips, 'The Trigan Empire' (1976-77) and 'Dan Dare' (1982-83). He co-founded Newsfield Publications with his brother, Franco, providing hundreds of covers and illustrations for their many computer and horror magazines. He later co-founded Thalamus Publishing.
