Upton Sinclair was a prolific American author, journalist, and political activist. 
Sinclair used his writing to trigger real legal changes. In 1906, he published a novel titled *The Jungle*. To prepare for this book, he spent seven weeks working undercover in Chicago meatpacking plants. He wanted to document the sanitary conditions and the struggles of immigrant laborers. The book caused a massive public outcry regarding food safety. This pressure helped lead to the passage of the Pure Food and Drug Act in 1906. It also led to the Meat Inspection Act later that same year. In 1919, he wrote *The Brass Check* to expose malpractice in American journalism. This book contributed to the creation of the first code of ethics for journalists four years later.
Sinclair's writing often focused on specific industrial sectors. He examined the coal, oil, and automotive industries through various novels. In *King Coal* (1917), he addressed the coal industry. His work *Oil!* (1927) explored the oil industry. In *The Flivver King* (1937), he described the rise of Henry Ford. This book detailed Ford's "wage reform" and his company's Sociological Department. It also traced Ford's decline into antisemitism through his publication, *The Dearborn Independent*. These books allowed readers to see the world from the perspectives of both workers and industrialists.
Sinclair's upbringing provided him with a unique view of social classes. He was born in Baltimore, Maryland, to Upton Beall Sinclair Sr. and Priscilla Harden Sinclair. 
Politics was a central part of Sinclair's life and identity. He was a longtime member of the Socialist Party, though he later joined the Democratic Party.
