Dietrich Graf von Hülsen-Haeseler (13 February 1852 – 14 November 1908) was an infantry general of the German Empire.
From May 1901 until his death in November 1908, von Hülsen-Haeseler served as Chief of the German Imperial Military Cabinet, during which time he rose to General of Infantry.
On 14 November 1908, Dietrich Graf von Hülsen-Haeseler died of a heart attack while on a hunting trip in honor of the Kaiser.
During a formal evening function, von Hülsen-Haeseler appeared dressed in the pink tutu and rose wreath of a ballerina, dancing for the Kaiser and his assembled guests.
[2] Apparently exhausted by his exertions, the general bowed, collapsed and was pronounced dead after hasty medical attention.
