The Jungle's influence has been extraordinary for a literary work. Upton Sinclair's 1906 landmark novel is widely credited with awakening the public fury that led to the passage of the Pure Food and Drug Act (1906), a watershed in consumer protection and government legislation.
Mr. Sinclair in The Jungle has given the world a close, a striking, and, we may say, in many ways a brilliant study of the great industries of Chicago. . . . The language Mr. Sinclair employs is appropriate to the scene, the action, and the characters of his drama. . . . The experienced reader will at once perceive that Mr. Sinclair has taken Zola for his model. The likeness is more than striking -- it fairly forces itself upon the attention of the reader. . . .He has not written a second Uncle Tom's Cabin. -- New York Times review, March 1906; Books of the Century
