A veteran of the American Civil War who fought at Shiloh and Chickamauga in the Union ranks, Bierce became one of America's best-known writers and journalists, admired for his insolent, entertaining and sometimes courageous columns.

Edgar Allan Poe (1809-1849) is one of America's greatest and best-loved writers.

Known as the father of the detective story, Poe is perhaps most famous for his short stories particularly his shrewd mysteries and chilling, often grotesque tales of horror he was also an extremely accomplished poet and a tough literary critic.

Poe's life was not far removed from the drama of his fiction. Orphaned at a young age, he was raised by a foster family. As a young man, he developed problems with gambling, debts, and alcohol, and was even dismissed from the army.

His love life was marked by tragedy and heartbreak. Despite these difficulties, Poe produced many works now considered essential to the American literary canon.

Arthur Machen (Arthur Llewelyn Jones), a Welsh author of supernatural, fantasy, and horror fiction, was born on March 3, 1863. He grew up in Caerleon, Monmouthshire, and attended boarding school at Hereford Cathedral School.

He moved to London in 1881 and worked as a journalist, children's tutor, and publisher's clerk, finding time to write at night. By 1894, Machen had his first major success.

The Great God Pan was published by John Lane, and despite widespread criticism for its sexual and horrific content, it sold well and went into a second edition.

In the 1920s Machen's work became immensely popular in the United States, but Machen experienced increasing poverty; he was saved in 1931 by receiving a Civil List pension from the British government. Arthur Machen died on March 30, 1947.

Guy de Maupassant was born in Normandy in 1850. In addition to his six novels, which include Bel-Ami (1885) and Pierre et Jean (1888), he wrote hundreds of short stories, the most famous of which is 'Boule de suif'.

By the late 1870s, he began to develop the first signs of syphilis, and in 1891 he was committed to an asylum in Paris, having tried to commit suicide. He died there two years later.
