30 June 1948
During his high school years in Switzerland, Frey followed an American correspondence course called The Famous Artists.
After spending six months in the Swiss army, and dropping out of Berne University, Frey moved to Britain once again and started a two-year course at the London Film School during which he supported himself with freelance work, including drawing historical illustrations for the War Picture Library.
As a child Frey loved The Eagle comic, and as an adult was able to fulfil his childhood dream by working on the revived version, drawing the strip Dan Dare. Also during the 1970s, he illustrated for IPC Media's Look and Learn magazine, including the strip The Trigan Empire.
When his brother Franco founded the computer magazine CRASH in 1983, together with Roger Kean, Oli became the magazine's illustrator. He also illustrated CRASH's sister magazines Zzap!64, Amtix and The Games Machine.
Through the late 1970s and the 1980s Frey was a prolific creator of gay erotic art including a series of a Tom of Finland-style bad-boy hero named "Rogue" for Him Magazine, and has produced, edited and illustrated several issues of Man-to-Man Magazine. During the late 90s, Frey worked as publishing director for Thalamus Publishing in Shropshire, which specialized in illustrated historical reference titles.
Thalamus Publishing went into receivership in August 2009.
Classic video gaming magazine Retro Gamer has featured Frey's artwork on its cover.
Oliver Frey is also known as Zack. Under the pseudonym Zack, Oliver Frey creates gay illustrations some of which are sold online. Other illustrations are used in his gay erotic novels in collaboration with his partner Roger Kean published under the pen name Zack including Boys of Vice City, Boys of Disco City, Boys of Two Cities, Bike Boy, Bike Boy Rides Again, and Hot for Boys: The Sexy Adventures of Rouge Zack is also the author of Zack the Art.
