Upton Sinclair
 | As a socialist and muckraker (term coined by Roosevelt for reporters who exposed injustices in the society), Upton Sinclair is famous for being the author of The Jungle, a novel written to expose the unsanitary conditions of meat-packing industries. The novel caused uproar. After reading the novel, President Theodore Roosevelt sent for investigations. This soon led to the passage of the Meat Inspection Act (1906) and the Pure Food and Drug Act. |
