William Butler Yeats was an Irish poet and playwright who won the Nobel Prize in Literature in 1923. He was a central figure of the “Irish Literary Revival,” which sought to revalue Irish culture and folklore.
In collections such as Fairy and Folk Tales of the Irish Peasantry (1888), he gathered and introduced fairy stories from around Ireland. He played a major role in making Irish fairies such as the leprechaun and the banshee known to the world.
