Upton Sinclair
Born in 1878 in Baltimore, Sinclair was an American novelist, essayist, “muckraker,” playwright, and short story writer, whose most famous book, The Jungle, exposed conditions in the meat packing industry. This book led to the Pure Food and Drug Act of 1906. His later works would also highlight major social and economic problems in the United States.  A socialist, Sinclair ran unsuccessfully for governor of California in 1934, and continued to write books into his old age.
