Born on September 20th, 1878, in Baltimore, Maryland, Upton Sinclair was a "muckraker" (An American journalist or writer who sought out to initiate social and political reforms). He wrote his first book, Springtime and Harvest, in 1901, which was a story of two lovers, inspired by his first unhappy marrige.

In 1906, Sinclair wrote "The Jungle," which was a book to protest the meatpacking industry. He wrote about how a man fell in a meat grinder, but they continued anyway.
He made political, economic, and social changes within his lifetime, as well as write over 90 books!
A complete genius of his time
