Upton Sinclair (1878–1968), born in Maryland, was a novelist and political writer whose works often focused on social injustices. His muck-raking novel The Jungle, about the working conditions in the meat-packing industry, led to the passage a few months later of the Pure Food and Drug Act and the Meat Inspection Act. His novel Dragon’s Teeth, a study of the rise of Nazism and part of the eleven-book Lanny Budd series, won the Pulitzer Prize in 1943. Sinclair died at the age of ninety, having written more than ninety books, thirty plays, and numerous works of journalism.
