Lincoln Steffens Was Considered a Reformer Specifically Because He Did What?

The answer

Lincoln Steffens was considered a reformer specifically because he exposed corruption in government and politics through investigative journalism. As one of the leading muckrakers of the Progressive Era, he researched and published detailed accounts of bribery, graft, and machine politics in American cities. His most famous work, "The Shame of the Cities" (1904) — a collection of articles first run in McClure's Magazine — documented how city officials, businessmen, and political bosses colluded to defraud the public.

Steffens did not hold office or write laws. His reform tool was exposure: by putting corruption in front of a mass readership, he created public outrage and pressure that pushed officials and voters toward reform. That is what makes him a reformer "specifically" — the act of investigating and revealing wrongdoing.

What the muckrakers did

"Muckrakers" was the label for a group of early-1900s investigative journalists who dug up (raked the muck of) social, political, and corporate abuses. President Theodore Roosevelt coined the term in 1906, borrowing an image from Pilgrim's Progress of a man so busy raking muck he never looked up. He meant it as a partial criticism — warning against relentless negativity — but the journalists wore it as a badge of honor. Their exposés fueled many Progressive reforms, from food-safety laws to anti-trust action to cleaner city government.

Steffens belongs alongside other famous muckrakers, and the exam-style answer is easiest to remember by contrast:

• Lincoln Steffens — political/municipal corruption (The Shame of the Cities).
• Ida Tarbell — the Standard Oil monopoly (The History of the Standard Oil Company).
• Upton Sinclair — the meatpacking industry (The Jungle).
• Jacob Riis — urban poverty and tenement slums (How the Other Half Lives).

The bigger picture

Steffens's importance is that he showed corruption was not a few bad apples but a system linking business and government across many cities. By naming that system publicly, he helped shift American attitudes and gave reformers ammunition. This is why quiz answers frame him as a reformer through journalism rather than through legislation or activism: his contribution was informing and mobilizing the public. Understanding the muckrakers as a group also clarifies why the correct answer is about exposing corruption — that shared mission is exactly what defined the movement Steffens helped lead.
