Horace Greeley was an American reformer and editor best remembered for launching the ‘New York Tribune.’ He is known as one of the most influential figures in publishing in the 1800s. With the help of his newspaper, he set out to educate and influence Americans on numerous social and economic issues like slavery, prostitution, capital punishment, alcoholism, and more. He was associated with the conservative Whig Party; however, on major issues like labor’s and women’s rights, he differed from his conservative colleagues. He was a trendsetter. Under his editorship, Margaret Fuller, who was a feminist, became the first female columnist in New York. In 1851, he wrote an editorial in which he wrote “Go west, young man.” This quote inspired many to set out and conquer the frontier. He was also the founder of the first temperance club in Vermont. He was a leading proponent of “associationism,” a movement that aspired to establish a new social and economic order based on Charles Fourier’s teachings. He was initially hesitant to join the anti-slavery movement, but once he did, he made every effort to convince the public about the evils of slavery.
