"The interest of the kaiser and court in dance had some odd but
 revealing overtones. Not infrequently, apparently, Dietrich Count von
 Hulsen-Haseler, chief of the military cabinet, would attire himself
 in a tutu and, before the kaiser and assembled guests, usually a
 mixed audience though never including the empress, would perform
 admirable pirouettes and arabesques. One such performace was to be
 Hulsen's last. In 1908, at the home of Max Egon Furst von
 Furstenberg, another close friend of Wilhelm's and an important
 foreign policy adviser, Hulsen danced and suddenly dropped dead of a
 heart attack."
