From Wikipedia: Edgar Allan Poe (January 19, 1809 – October 7, 1849) was an American writer, poet, author, editor, and literary critic who is best known for his poetry and short stories, particularly his tales of mystery and the macabre. He is widely regarded as a central figure of Romanticism and Gothic fiction in the United States, and of American literature. Poe was one of the country's earliest practitioners of the short story, and is considered the inventor of the detective fiction genre, as well as a significant contributor to the emerging genre of science fiction. He is the first well-known American writer to earn a living through writing alone, resulting in a financially difficult life and career.
Poe switched his focus to prose, and spent the next several years working for literary journals and periodicals, becoming known for his own style of literary criticism. His work forced him to move between several cities, including Baltimore, Philadelphia, and New York City. In 1836, he married his 13-year-old cousin, Virginia Clemm, but she died of tuberculosis in 1847. In January 1845, he published his poem "The Raven" to instant success. He planned for years to produce his own journal The Penn, later renamed The Stylus. But before it began publishing, Poe died in Baltimore in 1849, aged 40, under mysterious circumstances. The cause of his death remains unknown, and has been variously attributed to many causes including disease, alcoholism, substance abuse, and suicide.
