Klaus von Nichtssagend Gallery is a contemporary art gallery that opened as an artist-run project space in Williamsburg, Brooklyn, in fall 2004, before relocating to Manhattan in 2011 and settling into its current Tribeca space in April 2022. It is run by three owner-directors, Sam Wilson, Ingrid Bromberg Kennedy, and Rob Hult, who built the program around emerging artists making their New York debuts and have since expanded it to include more established names alongside artists nurtured early in the gallery's history. The gallery represents roughly two dozen artists, is a member of the Art Dealers Association of America and the New Art Dealers Alliance, and presents a rotating schedule of solo and group exhibitions.
