Samuel Hopkins Adams (January 26, 1871 - November 16, 1958) was an American writer, best known for his investigative journalism and muckraking. From 1891 to 1900, he was a reporter for the New York Sun where his career began, and then joined McClure's Magazine, where he gained a reputation as a muckraker for his articles on the conditions of public health in the United States. In 1904, Adams became an editorial staffer with McClure's Magazine working with Lincoln Steffens, Ida Tarbell, and Ray Stannard Baker. Adams considered himself a freelance writer and used his writings to support himself. In 1905, Adams was hired by Collier's to prepare articles on patent medicines.
