Stump the German

[Eva Elisabeth]

Very good, Steve, that is correct!

The place is the Beau-Rivage Hotel in Geneva that actually opened exactly one day prior to Lincoln's assassination, on April 13, 1865. It is still owned and run by the great-grandson of the founder and has several times been a fascinating setting in history.
In 1873, Charles II, Duke of Brunswick, died at the Beau-Rivage. The city of Geneva inherited 20 million gold francs from him. This money contributed to the construction of many buildings in Geneva, including its main theatre (Le Grand Théâtre).
On September 10, 1898, Austrian Empress Sissi was stabbed to death by Italian anarchist Luigi Lucheni, just when she left the Beau-Rivage on foot to catch the steamer for Montreux. She was carried back to the Beau-Rivage where she died soon afterwards. The reason of her visit btw. was a meeting with Baronesse Rothschild.
   
Lucheni's preserved head until 2000 was on display in a Vienna pathological museum. In 1987, a German politician was found dead in the bathtub of the suite where he stayed. The cause and circumstances of his death remain a mystery until today.
Eleanor Roosevelt was another famous guest, and during her stay she drafted parts of the Universal Declaration of Human Rights in her suite.
The Beau-Rivage was also the setting of the birth of former Czechoslovakia, whose independence from the Austrian - Hungarian Empire was signed there in 1918.

All who participated in this task win a stay at the suite where Sissi died (I think there's room for all, it is bigger than my apartment...):

My mother happened to stay in the hotel in the 1960s and has fond memories thereof.
