About the film
Herb and Dorothy is a 2008 documentary film by Megumi Sasaki. The film tells the story of two middle-class collectors of contemporary art, Herbert and Dorothy Vogel, and the enormous and valuable collection of conceptual art and minimalist art they amassed in spite of their relatively meager salaries as New York City civil servants. Many artists are interviewed in the film, including Christo, Chuck Close, Robert Mangold, and Pat Steir.
