Gerhart Johann Robert Hauptmann was a German dramatist and novelist. He is counted among the most important promoters of literary naturalism, though he integrated other styles into his work as well. He received the Nobel Prize in Literature in 1912.

Naturalism is a literary movement beginning in the late nineteenth century, similar to literary realism in its rejection of Romanticism, but distinct in its embrace of determinism, detachment, scientific objectivism, and social commentary. Literary naturalism emphasizes observation and the scientific method in the fictional portrayal of reality. Naturalism includes detachment, in which the author maintains an impersonal tone and disinterested point of view; determinism, which is defined as the opposite of free will, in which a character's fate has been decided, even predetermined, by impersonal forces of nature beyond human control; and a sense that the universe itself is indifferent to human life. The novel would be an experiment where the author could discover and analyze the forces, or scientific laws, that influenced behavior, and these included emotion, heredity, and environment. The movement largely traces to the theories of French author Émile Zola.
