Who influenced Edgar Allan Poe?

Over the last couple of hours I have been wandering the Internet, searching for interesting tidbits about writers of horror to post on my blog.  I have been noting how Algernon Blackwood, Arthur Machen, Lord Dunsany, and M.R. James and a host of others influenced Lovecraft, who in turn influenced Stephen King along with generations of writers and film producers, and how Poe influenced them all.  Of course, the next question that came to me was “who influenced Poe?”

I did a quick, cursory search of the Internet and found no good answer.   A few speculated that he was influenced by the events of his life (duh, aren’t we all?), while a few others speculated that he was influenced by other prominent authors of his time (again:  duh, aren’t we all).   No one I found yet seems to be able to cite Poe’s influences like they can of Lovecraft, King, or others.

Does anyone know of a reliable source that cites the authors that Poe read?

(February 17, 2013) Here is the beginning of an answer to my question.  Follow this link to the article “The Influence of E.T.A. Hoffmann on the Tales of Edgar Allan Poe” by Palmer Cobb, in Volume III of Studies in Philology, The University Press, Chapel Hill, 1908.
