Upton Sinclair

Upton Sinclair was an American novelist, muckraker, and political activist who was one of the most important social reformers of the early twentieth century. Born in 1878, he is best known for The Jungle, which exposed conditions in the meatpacking industry and led to major food safety legislation. His audiobooks and books offer listeners and readers some of the most important social reform literature in American history — fiction that changed laws and changed the world.
