Stump the German

[Eva Elisabeth]

Very smart thinking, Gene and Mike, but Roger nailed it! When serving as a secretary of the U.S. legation at Vienna, Hay wrote the "republican statement" to his boss John Bigelow on April 27, 1868, and about the Viennese cultural life in his memoirs.

Roger, I think the NYC Ballet is as superbe as the Wiener Staatsopernballett, so you win this wonderful "Walpurgis Night" scene from "Faust" by George Balanchine's NYC Ballet:

Having lived in Vienna for over six years, I have tried to find out private "Hay sites". The only place I could trace back was an inn, the "Golden Lamb", located in Praterstraße 7. Today, it's replaced by an office building of an insurance company.
