New York Tribune
Celebrated editor and political leader Horace Greeley (1811 - 1872) launched the New York Tribune in 1841.
From its pages, he had an enormous influence on American popular opinion. Greeley’s famous advice, "Go West, young man, go West," inspired generations of Americans to seek their fortunes on the new frontier. He advocated protectionism, abolition of slavery, labors rights, and political reform. Greeley ran for President against Ulysses S. Grant in 1872.

This triangular park in the heart of the old newspaper and printing district was named in Greeley’s honor. The City of New York acquired the site in 1846 in connection with the opening of Bloomingdale Road (now Broadway). The bronze monument of Greeley by sculptor Alexander Doyle was dedicated in 1890.
