Reconstructing Polyhedra

How little information is necessary to uniquely specify or reconstruct a polyhedron? For example, is it sufficient to know just the face normals and face areas? Is it sufficient to know only the intrinsic surface metric? Minkowski and Alexandrov say "yes" and "yes" respectively. This talk will present proofs of both results and extensions thereof.
