Edwin Arlington Robinson (1869-1935) was hailed by many in his day as America's foremost poet, outranking T.S. Eliot, Robert Frost, and Ezra Pound. Perhaps best known for his sonnets, he startles readers into attention and response through deliberate obscurity and ambiguity and demanding syntax. Many of Robinson's works continue to be published today, introducing him to new generations of readers.
