Doorway of 61 Washington Square South, March 1945.

Referred to as the “House of Genius,” the rowhouse at 61 Washington Square South was so named for the creative and bohemian writers, musicians, and artists that lived in the boarding house there. Madame Blanchard, a Swiss immigrant, began leasing the home in 1886. She converted the single-family home into a rooming house that only rented to creative types. Considered a cultural landmark, residents included writers Stephen Crane, O. Henry, and opera singer Adelina Patti.

The four-story red brick rowhouse, which had been constructed in the early to mid 19th century, was one of a row of similar buildings between West Broadway and Thompson Street, which all occupied a role as literary and artistic residences. In 1937 Madame Blanchard, the house matron died. In the 1940s, no. 61 and its neighbors were purchased by developer Anthony Campagna, who planned to demolish the row for a new apartment complex. In response to this plan, the neighbors and artists pushed back, establishing the Committee for the Washington Square Living Art Center. They hoped to retain the structures for a live and work art space. Despite their efforts, the residents were evicted and the buildings were razed in 1948. The developer did not construct the planned apartment house and instead sold the land to NYU, which built a student center. This failed preservation battle is considered the impetus for passionate preservation efforts by the neighborhood and the eventual designation of the Greenwich Village Historic District in 1969.
