Greeley, Horace. Born in 1811. American journalist and politician. Son of a New Hampshire farmer. Came to New York and, after some failures, established in 1841 the "New York Tribune," in which he supported Lincoln and the Union. In 1848, he became a member of Congress, and though prominent there, was one of the founders of the Republican Party in 1854. He ultimately, however, became a Democrat, and unsuccessfully opposed Grant for the presidency in 1872, but died the same year. He twice visited Europe. He was author of "The American Conflict," "What I Know About Farming," and "Recollections of a Busy Life."
