Art Collector Herbert Vogel Dies

Herbert Vogel, who, along with his wife Dorothy, amassed one of the most important collections of Minimalist art worldwide, died on Sunday at the age of 89.

A postal worker and a librarian, the couple used their modest salaries to collect works by artists including Sol LeWitt, Donald Judd, and Robert Mangold. 

A few years ago, the Vogels donated their entire collection to the National Gallery in Washington D.C. The Gallery is exhibiting about 1,000 of the donated works; the other pieces have been distributed in 50-item lots to one museum in each state, a project called Vogel 50x50.
