The Vogels, a postal worker and a librarian in NYC, began to collect minimalist, conceptual and post-minimalist art in the 1960’s and built the world’s foremost private collection over the subsequent 40 years.  Self-educated and tirelessly learning from artists, galleries, art periodicals, and their own painting and sense, they identified great talent in its early stages and bought seminal works, mostly drawings on paper, when they were still affordable.  Living in a one bedroom apartment on the Upper East Side, they stored hundreds of works under beds, behind couches, etc.  Known to the art world, they had a number of museum shows, but became famous through their donation to the National Gallery of Art of 4000 works and their donation of 2500 of those going to one museum in each of the 50 states.  Choosing the museums which vary from the famous (LA MOCA, Albright-Know, Seattle, Milwaukee) to the obscure university (Southern Illinois, South Dakota State) based on their own attachments, connections, and quirks, with the works also chosen by them, this is a unique donation.  Parallel, the artists range from the famous (LeWitt, Barnet, Tuttle, Lichtenstein, Poons)to the relatively unknown, and the works vary from classic abstract painting to Chamberlain’s car wreck sculptures.  At last, an organizing principle for art travel!
