Upton Sinclair
Upton Beall Sinclair, Jr. was a prolific American author known for his muckraking novels, particularly "The Jungle" (1906), which exposed the unsanitary conditions in Chicago's meat-packing industry.
His undercover research led to significant food safety reforms.
Sinclair's work often focused on social and political issues, including journalism ethics in "The Brass Check" (1919).
He won the Pulitzer Prize for Fiction in 1943.
Sinclair was also politically active, running for Congress as a Socialist and for Governor of California as a Democrat in 1934.
His progressive campaign was ultimately unsuccessful, but his writings continued to influence American society and politics throughout his career.
