Upton Sinclair(1878-1968)

Out of his own pocket, he sent copies of his novel "The Jungle" to every member of the U.S. Congress and then-President Theodore Roosevelt. Roosevelt, a voracious speed-reader who read several books a day, read Sinclair's novel and was horrified by the descriptions of conditions in the meat packing industry. He was inspired to champion for the passage of the Pure Food and Drug Act, which led to the founding of the Food and Drug Administration.
