Investigative Journalists: The Muckrakers


In this case study, you will learn about the muckrakers, a group of journalists at the turn of the twentieth century who were among the first to expose social and economic injustices through investigative reporting and photojournalism. You will then write a short news article on a current issue with a social justice focus. (Cover photo: Ida B. Wells. Illus. in The Afro-American Press and Its Editors, by I. Garland Penn., 1891.

"There was born in me a hatred of privilege, privilege of any sort."
—Ida Tarbell, muckraking journalist, who saw her father’s oil business fall apart when she was fifteen, after he refused a buyout from oil tycoon John D. Rockefeller

Essential Question

How did the muckrakers expose the corruption of the powerful?


Muckrakers were investigative journalists during the Progressive Era (1890s–1920s) who shone a light on corrupt business and government leaders as well as major social problems like racism.

Ida B. Wells wrote graphically about the horrors of lynching in the South. Her newspaper office was burned to the ground, and she was forced to move to Chicago after her own life became imperiled. Jacob Riis photographed immigrant children who lived among the garbage dumps underneath the wharves in New York City. Upton Sinclair wrote The Jungle, revealing the unsafe and unsanitary conditions in the meatpacking industry. Ida Tarbell wrote about the monopolistic practices of John D. Rockefeller’s Standard Oil Company, which destroyed small businesses, including her father’s.

Their reporting generated concern among members of the public and lawmakers, and in some cases, led to laws that addressed the problems they were covering. In other cases, problems were exposed but the groundswell of emotion led to little change.


The investigative techniques of the muckrakers included poring over documents, conducting countless interviews, and going undercover. This differed from yellow journalism, where some leading newspapers sensationalized stories using imagination rather than facts. In several cases, muckrakers became activists themselves and spent years speaking throughout the country about their work and the need for reform.

The term muckraking was coined by President Theodore Roosevelt in 1906, describing the crusading journalists who wrote stories in late nineteenth-century publications. Roosevelt took the word from the work The Pilgrim’s Progress by John Bunyan, written in 1678. Roosevelt criticized journalists he thought focused too much on exposing corruption in business and government and not reporting on more positive news. Journalists of the time largely took the term as a compliment and adopted it as a badge of honor for exposing misconduct.

Discuss the following questions:

  1. What are some examples of muckraking journalism during the Progressive Era?
  2. How did the investigative reporting of the muckrakers differ from the sensationalism of yellow journalism?
  3. What did President Theodore Roosevelt think of muckraker journalism? How did these journalists see themselves?
  4. How did photography such as Jacob Riis’s change the nature of journalism?


Ida Tarbell was born on the oil frontier of western Pennsylvania in 1857. She was among the first women to graduate from Allegheny College in 1880. After trying her hand at the more traditional woman’s job of teaching, Tarbell became a freelance writer and moved to Paris for over a decade before moving home and becoming editor of McClure’s Magazine, a new reform-minded publication, in 1894. Her History of the Standard Oil Company, published in 1904, exposed the ruthless business methods of John D. Rockefeller. It was a landmark work of the journalism that became known as "muckraking."

Jacob Riis was born in Denmark in 1849 and emigrated to the United States in 1870. He became a police reporter and with his camera, he began reporting on the harsh conditions of New York City’s tenement life. Riis’s pioneering techniques in investigative journalism and photojournalism laid the groundwork for social reform and supported efforts that were already underway. He published his works in books, newspapers, and magazines. In 1890, he published How the Other Half Lives, illustrated with photographs and statistics, which exposed the awful conditions in the streets and tenement housing of New York.

Upton Sinclair was born in Baltimore, Maryland in 1878. Sinclair’s parents raised him in contrasting worlds. His father was an alcoholic liquor salesman and his puritanical mother came from the upper class. His family moved to New York City when Upton was ten, and by age fourteen, he was selling children’s stories to magazines.

Rejecting his upper-class heritage, Sinclair became a socialist in 1903, and a year later set out to expose the mistreatment of workers in the meatpacking industry. The project would become the book The Jungle, one of the first works of fiction to lead directly to national legislation. The Federal Meat Inspection Act and the Pure Food and Drug Act of 1906 established the agency that eventually became the Food and Drug Administration in 1930. The book raised fundamental questions about the abuses of mechanized production.


Discuss the following questions:

  1. What might have been some of the difficulties Ida Tarbell faced in reporting on the ruthless business practices of the Standard Oil Company that other reporters didn’t face?
  2. How did Jacob Riis’s use of photography give more impact to his reporting on the living conditions in New York’s tenement housing?
  3. How did Upton Sinclair’s upper-class childhood give him a unique perspective to write about the mistreatment of workers in the meatpacking industry?

News Format

In the Progressive Era (1890s–1920s), newspapers and magazines dominated the market with large audiences. In the cases of Riis and Tarbell, their work appeared in newspapers or was serialized in magazines before they were turned into books. Sinclair published The Jungle, a work of fiction, which he then turned into a series of news articles.

The muckrakers’ investigative focus grew out of the nineteenth century’s age of “personal journalism” and “yellow journalism,” which used a strong editorial voice and was scandal focused, respectively. Many of the muckrakers came from both of these styles of journalism. And while yellow journalism deservedly got a bad name for its tactics, wrongdoing was often exposed alongside the sensationalism, enraging the public, leading to civic discourse, and, in certain cases, policy change.

Photojournalism played a key role in muckrakers’ work. Newspapers published stirring and stunning photographs of child labor and inhumane factory conditions. Drawings of the photographs would also appear in newspapers due to cost and the technology available at the time. See if you can make out the photo of the child in Riis’s Evening Sun article in the left column below.


Discuss the following questions:

  1. What are some similarities and differences between the news formats of muckrakers and investigative reporting on network and cable television and the Internet today?
  2. Why was the sensationalism of muckraking and yellow journalism successful in gaining the public’s attention regarding matters of reform?
