An enigmatic genius, Poe's contribution to the development of the detective story and science fiction genres is seminal. His literary craft is characterized by his keen psychological insights and attention to the darker aspects of the human psyche.

Poe's erudition is evident in his critiques, often blending gothic preoccupations with a unique aesthetic theory. His complex relationship with the American literary scene of the Nineteenth Century was underscored by his role as a critic, where he was as likely to praise as he was to excoriate his contemporaries.
