Prolific author and political activist Upton Sinclair throws the upheaval of the early twentieth century into sharp relief in 100%. In a matter of instants, a bomb blast transmutes Peter Gudge’s entire existence into chaos, and in the resulting pandemonium, he’s forced to reexamine all of his values and beliefs.

Upton Sinclair (September 20, 1878 – November 25, 1968) was an American writer who wrote nearly one hundred books and other works in several genres. Sinclair’s work was well-known and popular in the first half of the twentieth century, and he won the Pulitzer Prize for Fiction in 1943.

In 1906, Sinclair acquired particular fame for his classic muck-raking novel The Jungle, which exposed labor and sanitary conditions in the U.S. meat packing industry, causing a public uproar that contributed in part to the passage a few months later of the 1906 Pure Food and Drug Act and the Meat Inspection Act.

In 1919, he published The Brass Check, a muck-raking exposé of American journalism that publicized the issue of yellow journalism and the limitations of the «free press» in the United States. Four years after publication of The Brass Check, the first code of ethics for journalists was created. Time magazine called him «a man with every gift except humor and silence».

He is also well remembered for the line: «It is difficult to get a man to understand something, when his salary depends upon his not understanding it.» He used this line in speeches and the book about his campaign for governor as a way to explain why the editors and publishers of the major newspapers in California would not treat seriously his proposals for old age pensions and other progressive reforms.
