The Trespasser is the second novel written by D. H. Lawrence, published in 1912. Originally it was entitled the Saga of Siegmund and drew upon the experiences of a friend of Lawrence, Helen Corke, and her adulterous relationship with a married man that ended with his suicide. David Herbert Richards Lawrence (1885-1930) was a very important and controversial English writer of the 20th century, whose prolific and diverse output included novels, short stories, poems, plays, essays, travel books, paintings, translations, literary criticism and personal letters. His collected works represent an extended reflection upon the dehumanizing effects of modernity and industrialisation. In them, Lawrence confronts issues relating to emotional health and vitality, spontaneity, sexuality, and instinctive behaviour. Lawrence's unsettling opinions earned him many enemies and he endured hardships, official persecution, censorship and misrepresentation of his creative work throughout the second half of his life, much of which he spent in a voluntary exile he called his "savage pilgrimage." He is now generally valued as a visionary thinker and a significant representative of modernism in English literature.
