Dec 14, 1899. Julius H. Block, Esq., Moscow, Russia. My dear Block: This will introduce to you one of my old and valued partners, Mr. Sigmund Hergmann, who, for many years, was engaged in the electrical business for himself, in both New York and Berlin, Germany. He goes to Russia to look over the field generally, and I gladly give him a letter to you. Any courtesies extended to him will be very much appreciated by me. Yours very truly, Thomas A. Edison
