In 1893 Herr Doctor Professor Maximilian Eugen von Heydekampf went on an archaeological expedition to Zeus' temple in Delphi. He returned to Berlin with a number of artifacts including a Omphalos stone which were put on exhibit in the Old Museum.

In 1895 an imperial reception was held at the museum. Professor von Heydekampf's disappearance during this reception was never completely explained.
