“Herbert Vogel, an 82-year-old retired postal clerk, and his wife, Dorothy, 72, a former librarian, spent about 45 years and their life savings collecting Minimalist, Conceptual and post-1960s art. In 1992 the couple pledged more than 2,000 paintings, drawings and sculptures to the National Gallery of Art in Washington. Now, having amassed more art than could be exhibited in most museums, they will distribute 2,500 more pieces to institutions across the country.”
