Gérard Klein is a French science-fiction writer with sociological training.

He is editor of the prestigious collection Ailleurs et Demain and of the Livre de Poche science-fiction collection.

In his works, one novella is particularly striking, Les virus ne parlent pas ("The viruses do not speak"), where he imagines that the viruses have created all living beings in the same fashion that human beings have created computers, and for the same reason: to improve their efficiency. This work prefigures naturalist Richard Dawkins' The Selfish Gene, which deals with a similar subject: human beings can be considered as the "vehicles" used by their genes to make more copies of those genes. In Gérard Klein's novella, the creation escapes the intentions of its creator when humanity attempts to eliminate viruses. (See also golem, Karel Capek, and Isaac Asimov.)

Gérard Klein used Gilles d'Argyre pseudonym to sign his novels published in Fleuve Noir Anticipation collection.
