In her Wall Street Journal article about the preparation of objects for display in the National September 11 Memorial & Museum (“Restoring the Ruins”, June 25, 2014), Lee Rosenbaum focuses on conservators Steven Weintraub and John Childs and how they dealt with their mandate to preserve the objects that were destroyed in the attack on the World Trade Center while maintaining the integrity of the destruction. It is good to see an article about a museum in the general press that puts the work of its conservators front and center.
