Editor's note: The corner of Frankfort and Nassau streets (left) was occupied from 1812 through 1867 by the headquarters, or "wigwam", of Tammany Hall, a powerful political organization. Founded in 1788 as the the Society of St. Tammany, the organization evolved from a social organization into a political machine that dominated the Democratic party in New York City. It became notorious for the corruption practiced by the Tammany leaders, led by William Magear Tweed, a Fourth Ward native who controlled city government in the 1860s. Yet Tammany was supported by many working-class New Yorkers, particularly those of immigrant ancestry who appreciated its opposition to nativism and anti-Catholicism.

In 1868, the Tammany organization moved from the building at Frankfort and Nassau to a new headquarters (right) on 14th Street between Third Avenue and Irving Place. The building at Frankfort and Nassau was then occupied by the New York Sun, one of the city's leading newspapers. Founded by Benjamin H. Day in 1833, the Sun was New York's first example of the "Penny Press." It sold cheaply and included human interest stories and crime news aimed at a broad popular readership. On the same block of Nassau as the Sun stood the offices of several other newspapers. The block was called "newspaper row."
