While he was living in America, Padraic Colum started writing books for children. First he took an old story that was written in the Irish language and put it into English words. He did this because he did not want to forget the Irish language. He had this story published in the "New York Tribune". A man named Willy Pógany read the story and told Padraic he should make it into a long book. Willy Pógany was born in Hungary. His job was drawing pictures. Willy Pógany told Padraic that if Padraic wrote a book, Willy Pógany would draw the pictures. Padraic wrote the book, and Willy drew the pictures. The book was called "The King of Ireland's Son". It was published in 1916.
