Henry James (15 April 1843 - 28 February 1916) was an American author, who largely relocated to Europe as a young man and acquired British citizenship near the end of his life. James is regarded as a key transitional figure between literary realism and literary modernism, and is considered by many to be among the greatest novelists in the English language. He was the son of Henry James, Sr. and the brother of renowned philosopher and psychologist William James and diarist Alice James.
