The 12th International Congress on the Deterioration and Conservation of Stone took place on 22-26 October 2012 in New York City. More than 300 conservationists, material scientists, and scholars from 30 different countries in North and South America, Europe, North Africa, and Asia attended. The Congress featured 168 poster presentations, 78 oral presentations, and 13 tours on topics including documentation, forms and mechanisms of deterioration, and materials and methods of conservation. Sixteen organizations and individuals supported the conference, along with primary sponsors Columbia University and HPEF.
A fund was established in honor of Norman Weiss’s thirty-five years of teaching in the Historic Preservation Program at Columbia University. From this fund, the conference awarded twenty-two scholarships to help students traveling to New York for the conference. The Netherland-America Foundation provided three additional scholarships for students from the Netherlands.
