|Vol. VI.||May, 1896.||No. 6.|
Founded by S. S. McClure and John Sanborn Phillips (1861-1949), fellow classmate of Knox College, in June of 1893, the magazine featured political and literary content, and syndicated novels-in-progress a chapter at a time. In this way, McClure's published such writers as Rudyard Kipling, Robert Louis Stevenson, Jack London, Herminie T. Kavanagh, Willa Cather, and Arthur Conan Doyle. Mark Twain also contributed.
The magazine is credited with giving birth to muckraking journalism. Ida Tarbell's series in 1902 exposing the monopoly abuses of John D. Rockefeller's Standard Oil Company, and Ray Stannard Baker's earlier look at the United States Steel Corporation focused the public eye on the conduct of corporations and helped shape the moral compass of the time.
The writing staff defected in 1906 over disputes with McClure, forming The American Magazine. McClure's Magazine immediately began to lose readers and went into debt. S. S. McClure was forced to sell the magazine in 1911 to creditors. It was eventually retooled into a women's magazine and ran irregularly in this format. Publication in the periods from October 1921 to February 1922, September 1924 and April 1925, and February to May 1926. The later issues, beginning in July 1928 until the end, were named the New McClure's Magazine. The last issue was in March 1929 after which it was absorbed by The Smart Set.
