Frank Norris 
The Octopus, A Story of California 

Classic novel. According to Wikipedia: 'Benjamin Franklin Norris, Jr. (March 5, 1870 – October 25, 1902) was an American novelist, during the Progressive Era, writing predominantly in the naturalist genre. His notable works include Mc Teague (1899), The Octopus: A California Story (1901), and The Pit (1903). Although he did not openly support socialism as a political system, his work nevertheless evinces a socialist mentality and influenced socialist/progressive writers such as Upton Sinclair. Like many of his contemporaries, he was profoundly influenced by the advent of Darwinism, and Thomas Henry Huxley’s philosophical defense of it. Norris was particularly influenced by an optimistic strand of Darwinist philosophy taught by Joseph Le Conte, whom Norris studied under while at the University of California, Berkeley. Through many of his novels, notably Mc Teague, runs a preoccupation with the notion of the civilized man overcoming the inner 'brute, ’ his animalistic tendencies. His peculiar, and often confused, brand of Social Darwinism also bears the influence of the early criminologist Cesare Lombroso and the French naturalist Emile Zola.’
