Carlos Fuentes, one of the most prolific and best known Spanish-language authors, has died. His death was reported on Twitter by Mexican president Felipe Calderon. The Mexican daily Reforma, which Fuentes often wrote for, reports the author died after experiencing heart problems.
He was 83.
"I am profoundly sorry for the death our loved and admired Carlos Fuentes, writer and universal Mexican. Rest in peace," Calderon wrote on Twitter.
El País, the Spanish newspaper that carried some of his essays, confirmed his death.
El Universal spoke to Consuelo Saizar, director of the National Council for Culture and Arts, who said Fuentes possesed a "great literary body of work."
"He was a vital man like his prose," Saizar said. "And dies without his very much deserved Nobel prize."
In the United States, Fuentes is best known for his novel Gringo Viejo, or The Old Gringo, which was made into a film in 1989 starring Gregory Peck.
Among his major literary awards was the Cervantes Prize in 1987.
