Mr. Ralph Wiegandt, Assistant Director of Conservation and Mr.
Patrick Ravines, Senior Research Fellow  will present "Recent
Research in Daguerreotypes at George Eastman House."  The 2005
George Eastman House exhibition, "Young America, the Daguerreotypes

develop image-based condition databases, and establish a
standardized condition descriptive lexicon for Daguerreotypes.

development of an anoxic housing system for significant, at-risk

The Topics in Preservation Science lectures are free and open to the
public. For more information about this series, which is continually
