"Herb & Dorothy" tells the extraordinary story of Herbert Vogel, a postal clerk, and Dorothy Vogel, a librarian, who managed to build one of the most important contemporary art collections in history. In the early 1960s, Herb and Dorothy Vogel quietly began purchasing the works of unknown artists. Devoting all of Herb's salary to purchase art they liked, and living on Dorothy's paycheck alone, they continued collecting artworks guided by two rules: the piece had to be affordable, and it had to be small enough to fit in their one-bedroom Manhattan apartment. Within these limitations, they proved themselves curatorial visionaries; most of those they supported and befriended went on to become world-renowned artists. After thirty years, the Vogels managed to accumulate over 2,000 pieces. "Not even a toothpick could be squeezed into the apartment," recalls Dorothy. In 1992, the Vogels decided to move their entire collection to the National Gallery of Art in Washington, DC. The vast majority of their collection was given as a gift to the institution. Many of the works they acquired appreciated so significantly over the years that their collection today is worth millions of dollars. Still, the Vogels never sold a single piece. Today, Herb and Dorothy still live in the same apartment in New York with 19 turtles, lots of fish, and one cat. They've refilled it with piles of new art they've acquired.
