More Description

O'Brien was born Michael O'Brien in Cork, Ireland and was very young when the family moved to Limerick, Ireland. He attended the University of Dublin and is believed to have been a soldier in the British army at one time. On leaving college, he went to London and in the course of four years spent his inheritance of £8,000, meanwhile editing a periodical in aid of the World's Fair of 1851. About 1852 he emigrated to the United States, in the process changing his name to Fitz James, and thenceforth he devoted his attention to literature.

While he was in college he had shown an aptitude for writing verse, and two of his poems--Loch Ine and Irish Castles--were published in The Ballads of Ireland (1856).

His earliest writings in the United States were contributed to the Lantern, which was then edited by John Brougham. Subsequently, he wrote for the Home Journal, the New York Times, and the American Whig Review. His first important literary connection was with Harper's Magazine, and beginning in February 1853, with The Two Skulls, he contributed more than sixty articles in prose and verse to that periodical. He likewise wrote for the New York Saturday Press, Putnam's Magazine, Vanity Fair, and the Atlantic Monthly. To the latter, he sent "The Diamond Lens"[2] (1858) and "The Wonder Smith" (1859). "The Diamond Lens" is probably his most famous short story, and tells the story of a scientist who invents a powerful microscope and discovers a beautiful female in a microscopic world inside a drop of water. H.P. Lovecraft was an admirer of the work.[3] "The Wonder Smith" is an early predecessor of robot rebellion, where toys possessed by evil spirits are transformed into living automata who turn against their creators. His 1858 short story "From Hand to Mouth" has been referred to as "the single most striking example of surrealistic fiction to pre-date Alice in Wonderland" (Sam Moskowitz, 1971). "What Was It? A Mystery" (1859) is one of the earliest known examples of invisibility in fiction.
