Most people know Upton Sinclair for writing The Jungle, a muckraking novel about U.S. meat-packing that helped bring about legislative reforms of the food industry. In addition, Sinclair wrote a book, Oil!, satirizing the Teapot Dome scandal, tried starting a Utopian colony, and ran on the socialist ticket for Congress.
Upton Sinclair, a Socialist author who violated the Sunday laws at Wilmington, Del., decided to take an imprisonment of 18 hours rather than pay a $4 fine, and was put to breaking rock in the city workhouse. His offense was playing baseball and tennis on Sunday. Nine other men took the same punishment.
