Upton SinclairUpton Sinclair (1878-1968) was an American writer from Maryland. Though he wrote across many genres, Sinclair's most famous works were politically motivated. His self-published novel, The Jungle, exposed the labor conditions in the meatacking industry. This novel even inspired changes for working conditions and helped pass protection laws. The Brass Check exposed poor journalistic practices at the time and was also one of his most famous works. As a member of the socialist party, Sinclair attempted a few political runs but when defeated he returned to writing. Sinclair won the Pulitzer Prize in 1943 for Fiction. Several of his works were made into film adaptations and one earned two Oscars. Read More Read Less
