He also received the Cyrano award for lifetime achievement in the service of genre fiction and its actors.
Ayerdhal was born in the La Croix-Rousse area of Lyon.
In addition to his own writing career he devoted part of his time to supporting aspiring young authors and, with Le droit du Serf, to struggle with copyright law exceptions in the service of authors.
Ayerdhal held genre fiction in the highest regard, not only as a tool for learning but as tool for the expression of one's imagination and political inspirations.
He frequently used a quote from French philosopher Jean-Paul Sartre: "The writer's function is to make sure that no-one can ignore the world and that no-one can declare him/herself innocent."
