Your compassionate story about the exhibition of the Rausch collection in Frankfurt has touched me deeply (“The Caretakers’ Collection,” August 18, 2007). Hartmut and Helga Rausch, the caretakers of the Städelschule, Frankfurt’s art school, are showing some four-hundred gifts from thankful students and teachers both. Few of the works are signed. Most are small. None is labeled. And all come with a loving story about the artists. “For visitors,” you emphasize, “the show is a rare chance to see art that has been utterly insulated from commercialism from execution to acquisition to display.” The extraordinary collectors, who are nearing retirement as the school’s caretakers, would not sell anything in their eclectic collection. Would that the Rausch collection becomes an example to all and sundry. For commercialism threatens to smother art as we know it. Forever.
