Henry James, (15 April 1843 – 28 February 1916) was an American author 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 spent much of his life in England and became a British subject shortly before his death. He is primarily known for a series of major novels in which he portrayed the encounter of America with Europe. His plots centered on personal relationships, the proper exercise of power in such relationships, and other moral questions. His later works were increasingly experimental. In describing the internal states of mind and social dynamics of his characters, James often made use of a personal style in which ambiguous or contradictory motivations and impressions were overlaid or closely juxtaposed in the discussion of a single character’s psyche. An extraordinarily productive writer, in addition to his voluminous works of fiction he published articles and books of travel writing, biography, autobiography, and criticism,and wrote plays, some of which were performed during his lifetime with moderate success. His theatrical work is thought to have profoundly influenced his later novels and tales.
