Henry James, son of theologian Henry James Sr. and brother of the philosopher and psychologist William James and diarist Alice James, was an American-born author and literary critic of the late 19th and early 20th centuries. He spent much of his life in Europe and became a British subject shortly before his death. He is primarily known for novels, novellas and short stories based on themes of consciousness and morality. James significantly contributed to the criticism of fiction, particularly in his insistence that writers be allowed the greatest freedom possible in presenting their view of the world. His imaginative use of point of view, interior monologue and possibly unreliable narrators in his own novels and tales brought a new depth and interest to narrative fiction. An extraordinarily productive writer, he published substantive books of travel writing, biography, autobiography and visual arts criticism.
