In the history of corporate crime in America, Sinclair and other muckraking journalists focused on contemporary scandals such as the poor sanitation in food-processing plants, the large-scale adulteration of meat products, and the false claims of medicine advertisements, leading to massive public outrage. Sinclair’s writing drew the attention of the government as well as the public. Sinclair’s The Jungle not only caused a public uproar but also President Theodore Roosevelt read it and invited Sinclair to the White House to discuss the Chicago working situations of immigrants that he depicted in his novel. Sinclair contributed in the formulation of two powerful legislations, the Pure Food and Drug Act of 1906 and the Meat Inspection Act of the same year. Although his critics called Sinclair hysterical, unbalanced, and untruthful, he is a noted author and his book Dragon’s Teeth won the Pulitzer Price 1943. Some of his popular works are Sylvia (1913), Wide is the Gate (1943), and O Shepherd, Speak! (1949). His classical books are widely taught in schools and colleges today. Among the most influential books, The Jungle, The Wet Parade, and The Gnomobile were adapted for films.
