Writer, journalist, comic scriptwriter and host of television programs about books and authors. He was a university professor of literature until the advent of the military dictatorship in 1976. In 2014 he received the Konex Award, Short Story category: Quinquenio 2009-2013, and in January 2020 he was appointed director of the National Library of Argentina.

He wrote the scripts for the legendary Alberto Breccia’s drawings in the four volumes of the Perramus saga, a work of great prestige and popularity in the world of European graphic novels. It was translated into several different languages and won the Amnesty International award for the Francophone regions in 1988. Since the mid-eighties, he has published a dozen novels, four collections of short stories and several essays on the world of football, comics and graphic humour.

Both the series of crime novels featuring detective Etchenike (published in France by Gallimard in their Serie Noir) and the tales of adventure and novels for younger readers demonstrate a mastery of plot, action, use of popular language and the literary awareness needed to handle genres appropriately, in addition to his characteristic humour and irony.
