Lincoln Joseph Steffens (April 6, 1866 – August 9, 1936) was a New York reporter who launched a series of articles in McClure's that would later be published together in a book titled The Shame of the Cities. He is remembered for investigating corruption in municipal government in American cities and for his early support for the Soviet Union.
Steffens began his career as a journalist at the New York Evening Post. He later became an editor of McClure's magazine, where he became part of a celebrated muckraking trio with Ida Tarbell and Ray Stannard Baker. He specialized in investigating government and political corruption, and two collections of his articles were published as The Shame of the Cities (1904) and The Struggle for Self-Government (1906). He also wrote The Traitor State (1905), which criticized New Jersey for patronizing incorporation. In 1906, he left McClure's, along with Tarbell and Baker, to form The American Magazine. In The Shame of the Cities, Steffens sought to bring about political reform in urban America by appealing to the emotions of Americans. He tried to provoke outrage with examples of corrupt governments throughout urban America.
