Kletzker Brotherly Aid Association building, ca. 1978. The Kletzker Landsmannschaft, an aid organization for immigrants, was founded in 1892 by Jewish immigrants from Kletzk, Poland (near present-day Minsk, Belarus). The L-shaped building, which has an additonal entrance at 41 Canal Street, has since been a funeral home serving the Jewish, Italian, and Chinese communities of the Lower East Side.
