The tribune
Founded in 1847 as the Chicago Daily Tribune but was later transformed into Chicago Tribune after the arrival of Joseph Medell in 1855. Medell turned the newspaper into the leading voice for the Republican party and the leading newspaper against slavery. The Tribune became a key instrument in the election of Abraham Lincoln and the supporting of Emancipation Proclamation. The Tribune continued to grow under Medill's leadership, creating the company's distinct landmark of the Tribune Tower located in downtown Chicago. A decade later after the death of Medill in 1899, his son- in- law, Robert Patterson took control and mostly targeted the political corruption and investigations successfully being able drive out some senators out of Congress. Following to the 1910 to 50s, Medill's grandson Robert R. McCormick took control and expanded the newspaper production throughout Chicago, claiming his goal to be "The World's Greatest Newspaper." He succeeded in making the Tribune the primary newspaper in Chicago. With this influence, he was able to employ thousands of men and women into the company and use editorial pages to attack political ideals such as the New Deal and communism. After McCormick's death in 1955, The Tribune slowly lean toward the moderate (if not Republican) and continues to be the leading newspaper company in all of Chicago.
