Upon its release, Sinclair enlisted his fellow writer and friend Jack London to help publicize his book and assist in getting his message across to the masses. The Jungle became a massive bestseller and was translated into 17 languages within months of its release. Among its readers was President Theodore Roosevelt, who—despite his aversion to Sinclair’s politics—invited Sinclair to the White House and ordered an inspection of the meatpacking industry. As a result, the
Pure Food and Drug Act and the
Meat Inspection Act were both passed in 1906.
