The Jungle Illustrated

The Jungle is a 1906 novel by the American journalist and novelist Upton Sinclair (18781968). The novel portrays the harsh conditions and exploited lives of immigrants in the United States in Chicago and similar industrialized cities. Sinclair's primary purpose in describing the meat industry and its working conditions was to advance socialism in the United States. However, most readers were more concerned with several passages exposing health violations and unsanitary practices in the American meat packing industry during the early 20th century, which greatly contributed to a public outcry which led to reforms including the Meat Inspection Act. Sinclair said of the public reaction, "I aimed at the public's heart, and by accident I hit it in the stomach."
The book depicts working-class poverty, lack of social supports, harsh and unpleasant living and working conditions, and hopelessness among many workers. These elements are contrasted with the deeply rooted corruption of people in power. A review by the writer Jack London called it "the Uncle Tom's Cabin of wage slavery." Sinclair was considered a muckraker, a journalist who exposed corruption in government and business. In 1904, Sinclair had spent seven weeks gathering information while working incognito in the meatpacking plants of the Chicago stockyards for the socialist newspaper Appeal to Reason. He first published the novel in serial form in 1905 in the newspaper, and it was published as a book by Doubleday in 1906.
