auxiliary information: The Brown Building is a ten-story building that is part of the campus of New York University. It is located at 23-29 Washington Place, between Greene Street and Washington Square East in Greenwich Village, New York City. It was built in 1900‚Äì01, designed by John Woolley in the neo-Renaissance style. It was originally named the Asch Building after its owner, Joseph J. Asch. The top three floors of the building were at one time occupied by the Triangle Shirtwaist Factory, which was the site of the Triangle Shirtwaist Factory fire that killed 146 garment workers on March 25, 1911. The fire led to wide-ranging legislation requiring improved factory safety standards and helped spur the growth of the International Ladies' Garment Workers' Union. The building survived the fire and was refurbished. Three plaques on the southeast corner of the building commemorate the men and women who lost their lives in the fire. NYU began to use the eighth floor of the building for a library and classrooms in 1916. Real estate speculator and philanthropist Frederick Brown later bought the building and subsequently donated it to the university in 1929, where it was renamed as the Brown Building.
