Ambrose Gwinnett Bierce (June 24, 1842 – c. 1914) was an American author, journalist, and poet. A prolific and versatile writer, Bierce was regarded as one of the most influential journalists in the United States and as a pioneering writer of realist fiction. For his horror writing, Michael Dirda ranked him alongside Edgar Allan Poe and H. P. Lovecraft. S. T. Joshi speculates that he may well be the greatest satirist America has ever produced, and in this regard can take his place with such figures as Juvenal, Swift, and Voltaire. His war stories influenced Stephen Crane, Ernest Hemingway and others, and he was considered an influential and feared literary critic. In recent decades, Bierce has gained wider respect as a fabulist and poet.
His book The Devil's Dictionary was named one of "The 100 Greatest Masterpieces of American Literature" by the American Revolution Bicentennial Administration.
