Auden was close friends with Tolkien (of Lord of the Rings fame). He was a big fan of the little folk as well. Read what he had to say about Frodo Baggins in the New York Times review of Lord of the Rings.
To hear the New York Sun tell it, Auden's immigration to America (he hopped across the pond in the 1930s) marked an entire new period in American culture. You could call it the Auden Age. In fact, that's just what this author does. See how Auden has shaped American life here.
