Longtime denizens of the New York art scene, Herbie and Dorothy Vogel built up a world-class collection of modern art not through the power of the purse—he was a postal worker, she was a librarian—but through the power of perception, recognizing great talents early in their careers and buying their work when it was still affordable. Incredibly, when they could no longer jam anything else into their one-bedroom apartment in Manhattan, they donated a thousand pieces to the National Gallery in Washington, D.C., and set up a network to distribute nearly 4,000 others to museums in all 50 states. As this documentary by Megumi Sasaki shows, the Vogels excelled as collectors because they sought pleasure, not good investments, and because they thought like curators, often buying pieces that would trace an artist’s creative development. Tottering from gallery to gallery, they seem like your average old married couple, but with exceptionally good taste.
