found: E-mail from Johann Gaitzsch, editor of: Kreutzer, J. Trois rondeaux, op. 23, pour la guitare seule(In Dr. Gaitzsch's opinion, Joseph Kreutzer, the composer of the Trois rondeaux cannot be shown to be related to Rodolphe, Auguste Jean Nicholas, and Conradin Kreutzer. The erroneous birth and death dates formerly given for J. Kreutzer by Prat and McCutcheon are due to this confusion.)
