Upton Sinclair

Upton Beall Sinclair Jr. (1878–1968) was an American author, muckraker, journalist, and political activist who wrote close to 100 books. He achieved fame with his novel The Jungle (1906), exposing horrific conditions in Chicago's meatpacking industry and spurring passage of the Pure Food and Drug Act and Meat Inspection Act. An outspoken socialist, he ran unsuccessfully for office multiple times, including as the Democratic nominee for California governor in 1934, and won the Pulitzer Prize for Fiction in 1943 for Dragon's Teeth.
