Gabriel's reconstruction theorem says that a variety is completely recovered by its category of coherent sheaves. Over the years there have been some extensions of this result and I'll present yet another fresh new proof. Our* approach is moduli-theoretic rather than topological and makes it possible to extend the result to algebraic spaces. *This is joint work with M. Groechenig.
