"[1] Covering the Hollywood-based film industry (and particularly those aspects with a Sci-Fi or Fantasy bent), the Lofficiers wrote for a number of magazines created both for American and overseas audiences.

Their best-known works include a trilogy of DC Elseworlds based on German Expressionism cinema incorporating characters such as Superman, Batman and Wonder Woman, the Book of the Vishanti back-up feature for Doctor Strange: Sorcerer Supreme, two stories for Clive Barker’s Hellraiser, and the Tongue*Lash series for Dark Horse Comics.

Also for the French comic market, the Lofficiers wrote a trilogy of graphic novels based on the character of Robur created by Jules Verne.

In 1990, in recognition of their career as writers, translators and editors, the Lofficiers were presented with the Inkpot Award for Outstanding Achievement in Comic Arts.

In 2005, the Lofficiers started another small press, Rivière Blanche [fr],[8] to publish French science fiction novels in the nostalgic style of the long-defunct Anticipation imprint of Editions Fleuve Noir.
