Berthold Hartwig Arthur, Graf von Bernstorff (21 January 1842 – 12 February 1917) was a German politician, forester and landowner.

In August 1893, John Eric Banck [nl] sold the island to von Bernstorff.

[4] Von Bernstorff had planned to turn the island into a luxury holiday resort similar to Sylt, however the investments remained limited to a jetty and a little forest.

[5] Von Bernstroff died on 12 February 1917 in Höllwangen (nowadays part of Überlingen), Baden, at the age of 75.

[6] During World War II, it was owned by Bechtold Eugen von Bernstorff [nl], his grandson.
