Upton Sinclair (1878-1968) was born in Baltimore. At age fifteen, he began writing a series of dime novels in order to pay for his education at the City College of New York. He was later accepted to do graduate work at Columbia, and while there he published a number of novels, including The Journal of Arthur Stirling (1903) and Manassas (1904). Sinclair's breakthrough came in 1906 with the publication of The Jungle, a scathing indictment of the Chicago meat-packing industry. His later works include World's End (1940), Dragon's Teeth (1942), which won him a Pulitzer Prize, O Shepherd, Speak! (1949) and Another Pamela (1950).

Ronald Gottesman was born in Boston and earned degrees from the University of Massachusetts and from Colgate and Indiana universities. He taught literature, film studies, and humanities courses at Northwestern, Indiana, and Rutgers universities, the University of Wisconsin, and the University of Southern California, where for nine years he directed the Center for the Humanities. Founding editor of the Quarterly Review of Film Studies and Humanities in Society, Professor Gottesman was editor and author of many articles and books on literature and film, including three on Upton Sinclair.

Upton Sinclair's dramatic and deeply moving story exposed the brutal conditions in the Chicago stockyards at the turn of the nineteenth century and brought into sharp moral focus the apalling odds against which immigrants and other working people struggled for their share of the American dream. Denounced by the conservative press as an un-American libel on the meatpacking industry, the book was championed by more progressive thinkers, including then president Theodore Roosevelt, and was a major catalyst to the passing of the Pure Food and Meat Inspection act, which has tremendous impact to this day.
