He was a prolific us author who promoted socialist views and anarchist causes. he is most popular for writing "the jungle," dealing with the meat packing industry.

The author's name is Upton Sinclair.

Upton Sinclair was an American journalist and novelist. 'The Jungle', published in 1905, exposed the harsh reality of immigrants in the United States, particularly those who worked in the meat industry.

Sinclair describes the appealing conditions in meat packing plants in the USA as a way to advance socialism. The book concentrates around the life of a Lithuanian immigrant family who came to the USA to live the American dream. It portrays working class poverty, the lack of social supports, harsh living and working conditions in the factories.

"The Jungle" did not live up to its author's expectations as most readers were more concerned about the quality of meat being packed in the factories, health violations and unsanitary practices, than the plight of the workers. This public outcry led to the creation of the Federal Meat Inspection Act of 1906.
