His life is celebrated on this Spanish stamp, issued in 2015, that Eva sent me.
You can read about his many accomplishments on his wikipedia page. He was awarded the Nobel prize in Literature in 1982 for his body of work to that point that have themes of conflict and solitude, largely as they reflect life in the South American subcontinent, and are often written in the style known as magical realism. 'One Hundred Years of Solitude' is considered to be his masterpiece, which was published in 1967.
I have to confess I have never read any of his works.
